1.1 jsing 135: .Sh DESCRIPTION
136: .Nm OpenSSL
1.31 jmc 137: is a cryptography toolkit implementing the
138: Transport Layer Security
1.1 jsing 139: .Pq TLS v1
1.31 jmc 140: network protocol,
141: as well as related cryptography standards.
1.1 jsing 142: .Pp
143: The
144: .Nm
145: program is a command line tool for using the various
146: cryptography functions of
1.39 jmc 147: .Nm openssl Ns 's
1.33 jmc 148: crypto library from the shell.
1.1 jsing 149: .Pp
150: The pseudo-commands
151: .Cm list-standard-commands , list-message-digest-commands ,
152: and
153: .Cm list-cipher-commands
154: output a list
155: .Pq one entry per line
156: of the names of all standard commands, message digest commands,
157: or cipher commands, respectively, that are available in the present
158: .Nm
159: utility.
160: .Pp
161: The pseudo-commands
162: .Cm list-cipher-algorithms
163: and
164: .Cm list-message-digest-algorithms
165: list all cipher and message digest names,
166: one entry per line.
167: Aliases are listed as:
168: .Pp
1.33 jmc 169: .D1 from => to
1.1 jsing 170: .Pp
171: The pseudo-command
172: .Cm list-public-key-algorithms
173: lists all supported public key algorithms.
174: .Pp
175: The pseudo-command
1.39 jmc 176: .Cm no- Ns Ar command
1.1 jsing 177: tests whether a command of the
178: specified name is available.
1.39 jmc 179: If
180: .Ar command
181: does not exist,
1.1 jsing 182: it returns 0
183: and prints
1.39 jmc 184: .Cm no- Ns Ar command ;
1.1 jsing 185: otherwise it returns 1 and prints
1.39 jmc 186: .Ar command .
187: In both cases, the output goes to stdout and nothing is printed to stderr.
1.1 jsing 188: Additional command line arguments are always ignored.
189: Since for each cipher there is a command of the same name,
190: this provides an easy way for shell scripts to test for the
191: availability of ciphers in the
192: .Nm
193: program.
194: .Pp
195: .Sy Note :
1.39 jmc 196: .Cm no- Ns Ar command

1.1 jsing 223: .Pp
224: The
225: .Nm asn1parse
226: command is a diagnostic utility that can parse ASN.1 structures.
227: It can also be used to extract data from ASN.1 formatted data.
228: .Pp
229: The options are as follows:
230: .Bl -tag -width Ds
231: .It Fl dlimit Ar number
232: Dump the first
233: .Ar number
234: bytes of unknown data in hex form.

238: Generate encoded data based on string
239: .Ar str ,
240: file
241: .Ar file ,
1.34 jmc 242: or both, using the format described in
243: .Xr ASN1_generate_nconf 3 .
1.1 jsing 244: If only
245: .Ar file
246: is present then the string is obtained from the default section
247: using the name
248: .Dq asn1 .
1.84 jmc 249: The encoded data is passed through the ASN.1 parser and printed out as
1.1 jsing 250: though it came from a file;
251: the contents can thus be examined and written to a file using the
252: .Fl out
253: option.
254: .It Fl i
1.34 jmc 255: Indent the output according to the
1.1 jsing 256: .Qq depth

1.46 jmc 265: Do not output the parsed version of the input file.
1.1 jsing 266: .It Fl offset Ar number
1.34 jmc 267: Starting offset to begin parsing; the default is start of file.
1.1 jsing 268: .It Fl oid Ar file
269: A file containing additional object identifiers
270: .Pq OIDs .
271: If an OID
272: .Pq object identifier
273: is not part of
1.34 jmc 274: .Nm openssl Ns 's
1.1 jsing 275: internal table it will be represented in
276: numerical form
277: .Pq for example 1.2.3.4 .
1.34 jmc 278: .Pp
1.1 jsing 279: Each line consists of three columns:
280: the first column is the OID in numerical format and should be followed by
281: whitespace.
282: The second column is the
1.34 jmc 283: .Qq short name ,
1.1 jsing 284: which is a single word followed by whitespace.
285: The final column is the rest of the line and is the
286: .Qq long name .
287: .Nm asn1parse
288: displays the long name.
1.34 jmc 289: .It Fl out Ar file

352: The
353: .Nm ca
1.35 jmc 354: command is a minimal certificate authority (CA) application.
1.1 jsing 355: It can be used to sign certificate requests in a variety of forms
1.35 jmc 356: and generate certificate revocation lists (CRLs).
1.1 jsing 357: It also maintains a text database of issued certificates and their status.
358: .Pp
1.35 jmc 359: The options relevant to CAs are as follows:
1.1 jsing 360: .Bl -tag -width "XXXX"
361: .It Fl batch
1.41 jmc 362: Batch mode.
1.1 jsing 363: In this mode no questions will be asked
364: and all certificates will be certified automatically.
365: .It Fl cert Ar file
366: The CA certificate file.
367: .It Fl config Ar file
1.72 jmc 368: Specify an alternative configuration file.
1.91 schwarze 369: .It Fl create_serial
370: If reading the serial from the text file as specified in the
371: configuration fails, create a new random serial to be used as the
372: next serial number.
1.1 jsing 373: .It Fl days Ar arg
374: The number of days to certify the certificate for.
375: .It Fl enddate Ar date
1.41 jmc 376: Set the expiry date.
1.88 jmc 377: The format of the date is [YY]YYMMDDHHMMSSZ,
378: with all four year digits required for dates from 2050 onwards.
1.1 jsing 379: .It Fl extensions Ar section
380: The section of the configuration file containing certificate extensions
381: to be added when a certificate is issued (defaults to
1.35 jmc 382: .Cm x509_extensions
1.1 jsing 383: unless the
384: .Fl extfile
385: option is used).
386: If no extension section is present, a V1 certificate is created.
387: If the extension section is present
388: .Pq even if it is empty ,
389: then a V3 certificate is created.
1.91 schwarze 390: See the
391: .Xr x509v3.cnf 5
392: manual page for details of the extension section format.
1.1 jsing 393: .It Fl extfile Ar file
394: An additional configuration
395: .Ar file
396: to read certificate extensions from
397: (using the default section unless the
398: .Fl extensions
399: option is also used).
400: .It Fl in Ar file
401: An input
402: .Ar file
403: containing a single certificate request to be signed by the CA.
404: .It Fl infiles
405: If present, this should be the last option; all subsequent arguments
406: are assumed to be the names of files containing certificate requests.
1.91 schwarze 407: .It Fl key Ar password
408: The
409: .Fa password
410: used to encrypt the private key.
1.35 jmc 411: Since on some systems the command line arguments are visible,
412: this option should be used with caution.
1.1 jsing 413: .It Fl keyfile Ar file
414: The private key to sign requests with.
1.91 schwarze 415: .It Fl keyform Cm pem | der
1.1 jsing 416: Private key file format.

418: .Cm pem .
1.1 jsing 419: .It Fl md Ar alg
420: The message digest to use.
421: Possible values include
422: .Ar md5
423: and
424: .Ar sha1 .
425: This option also applies to CRLs.
426: .It Fl msie_hack
427: This is a legacy option to make
428: .Nm ca
429: work with very old versions of the IE certificate enrollment control
430: .Qq certenr3 .
431: It used UniversalStrings for almost everything.
432: Since the old control has various security bugs,
433: its use is strongly discouraged.
434: The newer control
435: .Qq Xenroll
436: does not need this option.
1.107 inoguchi 437: .It Fl multivalue-rdn
1.91 schwarze 438: This option causes the
439: .Fl subj
440: argument to be interpreted with full support for multivalued RDNs,
441: for example
442: .Qq "/DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe" .
443: If
1.107 inoguchi 444: .Fl multivalue-rdn
1.91 schwarze 445: is not used, the UID value is set to
446: .Qq "123456+CN=John Doe" .
1.1 jsing 447: .It Fl name Ar section
448: Specifies the configuration file
449: .Ar section
450: to use (overrides
451: .Cm default_ca
452: in the
453: .Cm ca
454: section).
455: .It Fl noemailDN
456: The DN of a certificate can contain the EMAIL field if present in the
1.30 mmcc 457: request DN, however it is good policy just having the email set into
1.1 jsing 458: the
1.35 jmc 459: .Cm altName
1.1 jsing 460: extension of the certificate.
461: When this option is set, the EMAIL field is removed from the certificate's
462: subject and set only in the, eventually present, extensions.
463: The
464: .Ar email_in_dn
465: keyword can be used in the configuration file to enable this behaviour.
466: .It Fl notext
467: Don't output the text form of a certificate to the output file.
468: .It Fl out Ar file
469: The output file to output certificates to.
470: The default is standard output.
1.91 schwarze 471: The certificate details will also be printed out to this file in
472: PEM format, except that
473: .Fl spkac
474: outputs DER format.
1.1 jsing 475: .It Fl outdir Ar directory
476: The
477: .Ar directory
478: to output certificates to.
479: The certificate will be written to a file consisting of the
480: serial number in hex with
481: .Qq .pem
482: appended.
483: .It Fl passin Ar arg
484: The key password source.
485: .It Fl policy Ar arg
1.41 jmc 486: Define the CA
1.1 jsing 487: .Qq policy
488: to use.
1.35 jmc 489: The policy section in the configuration file
490: consists of a set of variables corresponding to certificate DN fields.
491: The values may be one of
492: .Qq match
493: (the value must match the same field in the CA certificate),
494: .Qq supplied
495: (the value must be present), or
496: .Qq optional
497: (the value may be present).
498: Any fields not mentioned in the policy section
499: are silently deleted, unless the
500: .Fl preserveDN
501: option is set,
502: but this can be regarded more of a quirk than intended behaviour.
1.1 jsing 503: .It Fl preserveDN
504: Normally, the DN order of a certificate is the same as the order of the
505: fields in the relevant policy section.
506: When this option is set, the order is the same as the request.
507: This is largely for compatibility with the older IE enrollment control
508: which would only accept certificates if their DNs matched the order of the
509: request.
510: This is not needed for Xenroll.
1.91 schwarze 511: .It Fl selfsign
512: Indicates the issued certificates are to be signed with the key the
513: certificate requests were signed with, given with
514: .Fl keyfile .
515: Certificate requests signed with a different key are ignored.
516: If
517: .Fl gencrl ,
518: .Fl spkac ,
519: or
520: .Fl ss_cert
521: are given,
522: .Fl selfsign
523: is ignored.
524: .Pp
525: A consequence of using
526: .Fl selfsign
527: is that the self-signed certificate appears among the entries in
528: the certificate database (see the configuration option
529: .Cm database )
530: and uses the same serial number counter as all other certificates
531: signed with the self-signed certificate.
1.103 inoguchi 532: .It Fl sigopt Ar nm:v
533: Pass options to the signature algorithm during sign or certify operations.
534: The names and values of these options are algorithm-specific.
1.1 jsing 535: .It Fl spkac Ar file
536: A file containing a single Netscape signed public key and challenge,
537: and additional field values to be signed by the CA.
1.35 jmc 538: This will usually come from the
539: KEYGEN tag in an HTML form to create a new private key.
540: It is, however, possible to create SPKACs using the
541: .Nm spkac
542: utility.
543: .Pp
544: The file should contain the variable SPKAC set to the value of
545: the SPKAC and also the required DN components as name value pairs.
546: If it's necessary to include the same component twice,
547: then it can be preceded by a number and a
548: .Sq \&. .
1.1 jsing 549: .It Fl ss_cert Ar file
550: A single self-signed certificate to be signed by the CA.
551: .It Fl startdate Ar date
1.41 jmc 552: Set the start date.
1.88 jmc 553: The format of the date is [YY]YYMMDDHHMMSSZ,
554: with all four year digits required for dates from 2050 onwards.
1.91 schwarze 555: .It Fl subj Ar arg
556: Supersedes the subject name given in the request.
557: The
558: .Ar arg
559: must be formatted as
560: .Sm off
561: .Pf / Ar type0 Ns = Ar value0 Ns / Ar type 1 Ns = Ar value 1 Ns /
562: .Ar type2 Ns = Ar ... ;
563: .Sm on
564: characters may be escaped by
565: .Sq \e
566: .Pq backslash ,
567: no spaces are skipped.
568: .It Fl utf8
569: Interpret field values read from a terminal or obtained from a
570: configuration file as UTF-8 strings.
571: By default, they are interpreted as ASCII.
1.1 jsing 572: .It Fl verbose
1.41 jmc 573: Print extra details about the operations being performed.
1.1 jsing 574: .El
1.35 jmc 575: .Pp
576: The options relevant to CRLs are as follows:
1.1 jsing 577: .Bl -tag -width "XXXX"
578: .It Fl crl_CA_compromise Ar time
579: This is the same as
580: .Fl crl_compromise ,
581: except the revocation reason is set to CACompromise.
582: .It Fl crl_compromise Ar time
1.41 jmc 583: Set the revocation reason to keyCompromise and the compromise time to
1.1 jsing 584: .Ar time .
585: .Ar time
586: should be in GeneralizedTime format, i.e. YYYYMMDDHHMMSSZ.
587: .It Fl crl_hold Ar instruction
1.41 jmc 588: Set the CRL revocation reason code to certificateHold and the hold
1.1 jsing 589: instruction to
590: .Ar instruction
591: which must be an OID.
592: Although any OID can be used, only holdInstructionNone
593: (the use of which is discouraged by RFC 2459), holdInstructionCallIssuer or
594: holdInstructionReject will normally be used.
595: .It Fl crl_reason Ar reason
596: Revocation reason, where
597: .Ar reason
598: is one of:
599: unspecified, keyCompromise, CACompromise, affiliationChanged, superseded,
600: cessationOfOperation, certificateHold or removeFromCRL.
601: The matching of
602: .Ar reason
603: is case insensitive.
604: Setting any revocation reason will make the CRL v2.
605: In practice, removeFromCRL is not particularly useful because it is only used
606: in delta CRLs which are not currently implemented.
1.103 inoguchi 607: .It Fl crldays Ar days
1.1 jsing 608: The number of days before the next CRL is due.
609: This is the days from now to place in the CRL
1.35 jmc 610: .Cm nextUpdate
1.1 jsing 611: field.
612: .It Fl crlexts Ar section
613: The
614: .Ar section
615: of the configuration file containing CRL extensions to include.
616: If no CRL extension section is present then a V1 CRL is created;
617: if the CRL extension section is present
1.81 jmc 618: (even if it is empty)
1.1 jsing 619: then a V2 CRL is created.
1.81 jmc 620: The CRL extensions specified are CRL extensions and not CRL entry extensions.
621: It should be noted that some software can't handle V2 CRLs.
1.91 schwarze 622: See the
623: .Xr x509v3.cnf 5
624: manual page for details of the extension section format.
1.103 inoguchi 625: .It Fl crlhours Ar hours
1.1 jsing 626: The number of hours before the next CRL is due.
1.103 inoguchi 627: .It Fl crlsec Ar seconds
628: The number of seconds before the next CRL is due.
1.1 jsing 629: .It Fl gencrl
1.41 jmc 630: Generate a CRL based on information in the index file.
1.1 jsing 631: .It Fl revoke Ar file
632: A
633: .Ar file
634: containing a certificate to revoke.
1.91 schwarze 635: .It Fl status Ar serial
636: Show the status of the certificate with serial number
637: .Ar serial .
638: .It Fl updatedb
639: Update the database index to purge expired certificates.
1.1 jsing 640: .El
641: .Pp
1.35 jmc 642: Many of the options can be set in the
643: .Cm ca
644: section of the configuration file
645: (or in the default section of the configuration file),
646: specified using
647: .Cm default_ca
648: or
649: .Fl name .
650: The options
651: .Cm preserve
652: and
653: .Cm msie_hack
654: are read directly from the
655: .Cm ca
656: section.
1.1 jsing 657: .Pp
658: Many of the configuration file options are identical to command line
659: options.
660: Where the option is present in the configuration file and the command line,
661: the command line value is used.
662: Where an option is described as mandatory, then it must be present in
663: the configuration file or the command line equivalent
664: .Pq if any
665: used.
666: .Bl -tag -width "XXXX"
1.35 jmc 667: .It Cm certificate
1.1 jsing 668: The same as
669: .Fl cert .
670: It gives the file containing the CA certificate.
671: Mandatory.
1.35 jmc 672: .It Cm copy_extensions
1.1 jsing 673: Determines how extensions in certificate requests should be handled.
674: If set to
1.35 jmc 675: .Cm none
1.1 jsing 676: or this option is not present, then extensions are
677: ignored and not copied to the certificate.
678: If set to
1.35 jmc 679: .Cm copy ,
1.1 jsing 680: then any extensions present in the request that are not already present
681: are copied to the certificate.
682: If set to
1.35 jmc 683: .Cm copyall ,
1.1 jsing 684: then all extensions in the request are copied to the certificate:
685: if the extension is already present in the certificate it is deleted first.
1.35 jmc 686: .Pp
687: The
688: .Cm copy_extensions
689: option should be used with caution.
690: If care is not taken, it can be a security risk.
691: For example, if a certificate request contains a
692: .Cm basicConstraints
693: extension with CA:TRUE and the
694: .Cm copy_extensions
695: value is set to
696: .Cm copyall
697: and the user does not spot
1.91 schwarze 698: this when the certificate is displayed, then this will hand the requester
1.35 jmc 699: a valid CA certificate.
700: .Pp
701: This situation can be avoided by setting
702: .Cm copy_extensions
703: to
704: .Cm copy
705: and including
706: .Cm basicConstraints
707: with CA:FALSE in the configuration file.
708: Then if the request contains a
709: .Cm basicConstraints
710: extension, it will be ignored.
1.1 jsing 711: .Pp
712: The main use of this option is to allow a certificate request to supply
713: values for certain extensions such as
1.35 jmc 714: .Cm subjectAltName .
715: .It Cm crl_extensions
1.1 jsing 716: The same as
717: .Fl crlexts .
1.35 jmc 718: .It Cm crlnumber
1.1 jsing 719: A text file containing the next CRL number to use in hex.
720: The CRL number will be inserted in the CRLs only if this file exists.
721: If this file is present, it must contain a valid CRL number.
1.35 jmc 722: .It Cm database
1.1 jsing 723: The text database file to use.
724: Mandatory.
725: This file must be present, though initially it will be empty.
1.35 jmc 726: .It Cm default_crl_hours , default_crl_days
1.1 jsing 727: The same as the
728: .Fl crlhours
729: and
730: .Fl crldays
731: options.
732: These will only be used if neither command line option is present.
733: At least one of these must be present to generate a CRL.
1.35 jmc 734: .It Cm default_days
1.1 jsing 735: The same as the
736: .Fl days
737: option.
738: The number of days to certify a certificate for.
1.35 jmc 739: .It Cm default_enddate
1.1 jsing 740: The same as the
741: .Fl enddate
742: option.
743: Either this option or
1.35 jmc 744: .Cm default_days
1.1 jsing 745: .Pq or the command line equivalents
746: must be present.
1.35 jmc 747: .It Cm default_md
1.1 jsing 748: The same as the
749: .Fl md
750: option.
751: The message digest to use.
752: Mandatory.
1.35 jmc 753: .It Cm default_startdate
1.1 jsing 754: The same as the
755: .Fl startdate
756: option.
757: The start date to certify a certificate for.
758: If not set, the current time is used.
1.35 jmc 759: .It Cm email_in_dn
1.1 jsing 760: The same as
761: .Fl noemailDN .
762: If the EMAIL field is to be removed from the DN of the certificate,
763: simply set this to
764: .Qq no .
765: If not present, the default is to allow for the EMAIL field in the
766: certificate's DN.
1.35 jmc 767: .It Cm msie_hack
1.1 jsing 768: The same as
769: .Fl msie_hack .
1.35 jmc 770: .It Cm name_opt , cert_opt
1.1 jsing 771: These options allow the format used to display the certificate details
772: when asking the user to confirm signing.
773: All the options supported by the
774: .Nm x509
775: utilities'
776: .Fl nameopt
777: and
778: .Fl certopt
779: switches can be used here, except that
1.35 jmc 780: .Cm no_signame
1.1 jsing 781: and
1.35 jmc 782: .Cm no_sigdump
1.1 jsing 783: are permanently set and cannot be disabled
784: (this is because the certificate signature cannot be displayed because
785: the certificate has not been signed at this point).
786: .Pp
787: For convenience, the value
1.35 jmc 788: .Cm ca_default
1.1 jsing 789: is accepted by both to produce a reasonable output.
790: .Pp
791: If neither option is present, the format used in earlier versions of
1.35 jmc 792: .Nm openssl
1.1 jsing 793: is used.
1.81 jmc 794: Use of the old format is strongly discouraged
795: because it only displays fields mentioned in the
1.35 jmc 796: .Cm policy
1.1 jsing 797: section,
798: mishandles multicharacter string types and does not display extensions.
1.35 jmc 799: .It Cm new_certs_dir
1.1 jsing 800: The same as the

809: by whitespace and finally the long name.
1.35 jmc 810: .It Cm oid_section
1.1 jsing 811: This specifies a section in the configuration file containing extra
812: object identifiers.
813: Each line should consist of the short name of the object identifier
814: followed by

2671: options.
2672: .It Fl no_cert_checks
2673: Don't perform any additional checks on the OCSP response signer's certificate.
2674: That is, do not make any checks to see if the signer's certificate is
2675: authorised to provide the necessary status information:
2676: as a result this option should only be used for testing purposes.
2677: .It Fl no_cert_verify
2678: Don't verify the OCSP response signer's certificate at all.
2679: Since this option allows the OCSP response to be signed by any certificate,
2680: it should only be used for testing purposes.
2681: .It Fl no_certs
1.55 jmc 2682: Don't include any certificates in the signed request.
1.1 jsing 2683: .It Fl no_chain

1.55 jmc 2705: option no nonce is added:
1.1 jsing 2706: using the
2707: .Fl nonce
1.55 jmc 2708: option will force the addition of a nonce.
1.1 jsing 2709: If an OCSP request is being created (using the
2710: .Fl cert
2711: and
2712: .Fl serial
2713: options)
1.55 jmc 2714: a nonce is automatically added; specifying

2716: overrides this.
2717: .It Fl noverify
1.55 jmc 2718: Don't attempt to verify the OCSP response signature or the nonce values.
2719: This is normally only be used for debugging
1.1 jsing 2720: since it disables all verification of the responder's certificate.

2726: .It Fl reqin Ar file , Fl respin Ar file
2727: Read an OCSP request or response file from
2728: .Ar file .
2729: These options are ignored
2730: if an OCSP request or response creation is implied by other options
2731: (for example with the

2742: option except the certificate with serial number
2743: .Ar num
2744: is added to the request.
2745: The serial number is interpreted as a decimal integer unless preceded by
2746: .Sq 0x .
1.55 jmc 2747: Negative integers can also be specified
2748: by preceding the value with a minus sign.

2755: .Fl signkey
2756: option.
2757: If the
2758: .Fl signkey
2759: option is not present, then the private key is read from the same file

2763: Connection timeout to the OCSP responder in seconds.
1.1 jsing 2764: .It Fl trust_other

2783: .It Fl validity_period Ar nsec , Fl status_age Ar age
1.55 jmc 2784: The range of times, in seconds, which will be tolerated in an OCSP response.
2785: Each certificate status response includes a notBefore time
2786: and an optional notAfter time.
1.1 jsing 2787: The current time should fall between these two values,
2788: but the interval between the two times may be only a few seconds.
2789: In practice the OCSP responder and clients' clocks may not be precisely
2790: synchronised and so such a check may fail.
2791: To avoid this the
2792: .Fl validity_period
2793: option can be used to specify an acceptable error range in seconds,
1.55 jmc 2794: the default value being 5 minutes.
1.1 jsing 2795: .Pp
1.55 jmc 2796: If the notAfter time is omitted from a response,
2797: it means that new status information is immediately available.
2798: In this case the age of the notBefore field is checked
2799: to see it is not older than
1.1 jsing 2800: .Ar age
2801: seconds old.
2802: By default, this additional check is not performed.
2803: .It Fl verify_other Ar file
1.55 jmc 2804: A file containing additional certificates to search
2805: when attempting to locate the OCSP response signing certificate.
2806: Some responders omit the actual signer's certificate from the response,
2807: so this can be used to supply the necessary certificate.
1.1 jsing 2808: .El

2820: containing certificate revocation information.
1.1 jsing 2821: .Pp
1.55 jmc 2822: If this option is specified,
1.1 jsing 2823: .Nm ocsp
1.55 jmc 2824: is in responder mode, otherwise it is in client mode.
2825: The requests the responder processes can be either specified on
1.1 jsing 2826: the command line (using the

2828: and
2829: .Fl serial
2830: options), supplied in a file (using the

2836: is specified).
2837: .Pp
1.55 jmc 2838: If this option is present, then the

2849: used in the nextUpdate field.
2850: If neither option is present,
2851: the nextUpdate field is omitted,

2874: .It Fl rsigner Ar file
2875: The certificate to sign OCSP responses with.
2876: .El
2877: .Pp
2878: Initially the OCSP responder certificate is located and the signature on
2879: the OCSP request checked using the responder certificate's public key.
2880: Then a normal certificate verify is performed on the OCSP responder certificate
2881: building up a certificate chain in the process.
2882: The locations of the trusted certificates used to build the chain can be
2883: specified by the
2884: .Fl CAfile
2885: and
2886: .Fl CApath
2887: options or they will be looked for in the standard
1.55 jmc 2888: .Nm openssl
2889: certificates directory.
1.1 jsing 2890: .Pp
1.55 jmc 2891: If the initial verify fails, the OCSP verify process halts with an error.
1.1 jsing 2892: Otherwise the issuing CA certificate in the request is compared to the OCSP
2893: responder certificate: if there is a match then the OCSP verify succeeds.
2894: .Pp
2895: Otherwise the OCSP responder certificate's CA is checked against the issuing
2896: CA certificate in the request.
2897: If there is a match and the OCSPSigning extended key usage is present
2898: in the OCSP responder certificate, then the OCSP verify succeeds.
2899: .Pp
2900: Otherwise the root CA of the OCSP responder's CA is checked to see if it
2901: is trusted for OCSP signing.
2902: If it is, the OCSP verify succeeds.
2903: .Pp
2904: If none of these checks is successful, the OCSP verify fails.
2905: What this effectively means is that if the OCSP responder certificate is
2906: authorised directly by the CA it is issuing revocation information about
1.55 jmc 2907: (and it is correctly configured),
1.1 jsing 2908: then verification will succeed.
2909: .Pp
1.55 jmc 2910: If the OCSP responder is a global responder,
2911: which can give details about multiple CAs
2912: and has its own separate certificate chain,
2913: then its root CA can be trusted for OCSP signing.
1.1 jsing 2914: Alternatively, the responder certificate itself can be explicitly trusted
2915: with the

3301: To discourage attacks by using large dictionaries of common passwords,
3302: the algorithm that derives keys from passwords can have an iteration count
3303: applied to it: this causes a certain part of the algorithm to be repeated
3304: and slows it down.

3306: have the same password as the keys and certificates it could also be attacked.
3307: By default, both MAC and encryption iteration counts are set to 2048;
3308: using these options the MAC and encryption iteration counts can be set to 1.

3969: it disables prompting of certificate fields
1.1 jsing 3970: and just takes values from the config file directly.
3971: It also changes the expected format of the
1.63 jmc 3972: .Cm distinguished_name
1.1 jsing 3973: and
1.63 jmc 3974: .Cm attributes
1.1 jsing 3975: sections.

1.63 jmc 3986: .It Cm utf8only
3987: UTF8String.
1.1 jsing 3988: This is the default, as recommended by PKIX in RFC 2459.
1.63 jmc 3989: .It Cm default
3990: PrintableString, IA5String, T61String, BMPString, UTF8String.
3991: .It Cm pkix
3992: PrintableString, IA5String, BMPString, UTF8String.
3993: Inspired by the PKIX recommendation in RFC 2459 for certificates
3994: generated before 2004, but differs by also permitting IA5String.
3995: .It Cm nombstr
3996: PrintableString, IA5String, T61String, UniversalString.
3997: A workaround for some ancient software that had problems

1.72 jmc 4018: command line switch.
1.1 jsing 4019: .El
1.63 jmc 4020: .Pp
1.1 jsing 4021: There are two separate formats for the distinguished name and attribute
4022: sections.
4023: If the
4024: .Fl prompt
4025: option is set to
1.63 jmc 4026: .Qq no ,
1.72 jmc 4027: then these sections just consist of field names and values.
4028: If the
1.1 jsing 4029: .Fl prompt
4030: option is absent or not set to
1.63 jmc 4031: .Qq no ,
1.72 jmc 4032: then the file contains field prompting information of the form:
1.1 jsing 4033: .Bd -unfilled -offset indent
4034: fieldName="prompt"
4035: fieldName_default="default field value"
4036: fieldName_min= 2
4037: fieldName_max= 4
4038: .Ed
4039: .Pp
4040: .Qq fieldName
4041: is the field name being used, for example
1.63 jmc 4042: .Cm commonName
4043: (or CN).
1.1 jsing 4044: The
4045: .Qq prompt
4046: string is used to ask the user to enter the relevant details.
4047: If the user enters nothing, the default value is used;
4048: if no default value is present, the field is omitted.
4049: A field can still be omitted if a default value is present,
4050: if the user just enters the
4051: .Sq \&.
4052: character.
4053: .Pp
4054: The number of characters entered must be between the
1.63 jmc 4055: fieldName_min and fieldName_max limits:
1.1 jsing 4056: there may be additional restrictions based on the field being used
4057: (for example
1.63 jmc 4058: .Cm countryName
1.1 jsing 4059: can only ever be two characters long and must fit in a
1.63 jmc 4060: .Cm PrintableString ) .
1.1 jsing 4061: .Pp
4062: Some fields (such as
1.63 jmc 4063: .Cm organizationName )
1.1 jsing 4064: can be used more than once in a DN.
4065: This presents a problem because configuration files will
4066: not recognize the same name occurring twice.
4067: To avoid this problem, if the
1.63 jmc 4068: .Cm fieldName
1.1 jsing 4069: contains some characters followed by a full stop, they will be ignored.
4070: So, for example, a second
1.63 jmc 4071: .Cm organizationName
1.1 jsing 4072: can be input by calling it
4073: .Qq 1.organizationName .
4074: .Pp
4075: The actual permitted field names are any object identifier short or
4076: long names.
4077: These are compiled into
1.63 jmc 4078: .Nm openssl
1.1 jsing 4079: and include the usual values such as
1.63 jmc 4080: .Cm commonName , countryName , localityName , organizationName ,
1.89 jmc 4081: .Cm organizationalUnitName , stateOrProvinceName .
1.1 jsing 4082: Additionally,
1.63 jmc 4083: .Cm emailAddress
1.1 jsing 4084: is included as well as
1.63 jmc 4085: .Cm name , surname , givenName , initials
1.1 jsing 4086: and
1.63 jmc 4087: .Cm dnQualifier .
1.1 jsing 4088: .Pp
4089: Additional object identifiers can be defined with the
1.63 jmc 4090: .Cm oid_file
1.1 jsing 4091: or
1.63 jmc 4092: .Cm oid_section
1.1 jsing 4093: options in the configuration file.
4094: Any additional fields will be treated as though they were a

1.1 jsing 5549: .Pp
5550: The
5551: .Nm ts
5552: command is a basic Time Stamping Authority (TSA) client and server
5553: application as specified in RFC 3161 (Time-Stamp Protocol, TSP).
5554: A TSA can be part of a PKI deployment and its role is to provide long
1.72 jmc 5555: term proof of the existence of specific data.
1.1 jsing 5556: Here is a brief description of the protocol:
5557: .Bl -enum
5558: .It
5559: The TSA client computes a one-way hash value for a data file and sends
5560: the hash to the TSA.
5561: .It
5562: The TSA attaches the current date and time to the received hash value,
5563: signs them and sends the time stamp token back to the client.
5564: By creating this token the TSA certifies the existence of the original
5565: data file at the time of response generation.
5566: .It
5567: The TSA client receives the time stamp token and verifies the
5568: signature on it.
5569: It also checks if the token contains the same hash
5570: value that it had sent to the TSA.
5571: .El
5572: .Pp
5573: There is one DER-encoded protocol data unit defined for transporting a time
5574: stamp request to the TSA and one for sending the time stamp response
5575: back to the client.
5576: The
5577: .Nm ts
5578: command has three main functions:
5579: creating a time stamp request based on a data file;
5580: creating a time stamp response based on a request;
5581: and verifying if a response corresponds
5582: to a particular request or a data file.
5583: .Pp
5584: There is no support for sending the requests/responses automatically
5585: over HTTP or TCP yet as suggested in RFC 3161.
5586: Users must send the requests either by FTP or email.
5587: .Pp
5588: The
5589: .Fl query
5590: switch can be used for creating and printing a time stamp
5591: request with the following options:
5592: .Bl -tag -width Ds
5593: .It Fl cert
1.72 jmc 5594: Expect the TSA to include its signing certificate in the response.
1.1 jsing 5595: .It Fl config Ar configfile

1.1 jsing 6003: The

6005: program uses the same functions as the internal SSL and S/MIME verification,
1.76 jmc 6006: with one crucial difference:
6007: wherever possible an attempt is made to continue after an error,
6008: whereas normally the verify operation would halt on the first error.
1.1 jsing 6009: This allows all the problems with a certificate chain to be determined.
6010: .Pp
1.76 jmc 6011: The verify operation consists of a number of separate steps.
1.1 jsing 6012: Firstly a certificate chain is built up starting from the supplied certificate
6013: and ending in the root CA.
6014: It is an error if the whole chain cannot be built up.
6015: The chain is built up by looking up the issuer's certificate of the current
6016: certificate.
6017: If a certificate is found which is its own issuer, it is assumed
6018: to be the root CA.
6019: .Pp
1.76 jmc 6020: All certificates whose subject name matches the issuer name
1.1 jsing 6021: of the current certificate are subject to further tests.
6022: The relevant authority key identifier components of the current certificate
1.76 jmc 6023: (if present) must match the subject key identifier (if present)
6024: and issuer and serial number of the candidate issuer;
6025: in addition the
6026: .Cm keyUsage
6027: extension of the candidate issuer (if present) must permit certificate signing.
1.1 jsing 6028: .Pp
6029: The lookup first looks in the list of untrusted certificates and if no match
6030: is found the remaining lookups are from the trusted certificates.
1.76 jmc 6031: The root CA is always looked up in the trusted certificate list:
6032: if the certificate to verify is a root certificate,
6033: then an exact match must be found in the trusted list.
1.1 jsing 6034: .Pp
6035: The second operation is to check every untrusted certificate's extensions for
6036: consistency with the supplied purpose.
6037: If the
6038: .Fl purpose
6039: option is not included, then no checks are done.
6040: The supplied or
6041: .Qq leaf
6042: certificate must have extensions compatible with the supplied purpose
6043: and all other certificates must also be valid CA certificates.
6044: The precise extensions required are described in more detail in
6045: the
1.76 jmc 6046: .Nm X509
1.1 jsing 6047: section below.
6048: .Pp
6049: The third operation is to check the trust settings on the root CA.
6050: The root CA should be trusted for the supplied purpose.
1.76 jmc 6051: A certificate with no trust settings is considered to be valid for
1.1 jsing 6052: all purposes.
6053: .Pp
6054: The final operation is to check the validity of the certificate chain.
6055: The validity period is checked against the current system time and the
1.76 jmc 6056: .Cm notBefore
1.1 jsing 6057: and
1.76 jmc 6058: .Cm notAfter
1.1 jsing 6059: dates in the certificate.
6060: The certificate signatures are also checked at this point.
6061: .Pp
6062: If all operations complete successfully, the certificate is considered
6063: valid.
6064: If any operation fails then the certificate is not valid.
6065: When a verify operation fails, the output messages can be somewhat cryptic.
6066: The general form of the error message is:
1.76 jmc 6067: .Bd -literal
6068: server.pem: /C=AU/ST=Queensland/O=CryptSoft Pty Ltd/CN=Test CA (1024-bit)
6069: error 24 at 1 depth lookup:invalid CA certificate

6072: The first line contains the name of the certificate being verified, followed by
6073: the subject name of the certificate.
6074: The second line contains the error number and the depth.
6075: The depth is the number of the certificate being verified when a
6076: problem was detected starting with zero for the certificate being verified
6077: itself, then 1 for the CA that signed the certificate and so on.
6078: Finally a text version of the error number is presented.

6516: (multiple AVAs are very rare and their use is discouraged).
6517: The options ending in
6518: .Qq space
6519: additionally place a space after the separator to make it more readable.
6520: .Cm sep_multiline
6521: uses a linefeed character for the RDN separator and a spaced
6522: .Sq +
6523: for the AVA separator,
6524: as well as indenting the fields by four characters.
6525: .It Cm show_type
1.84 jmc 6526: Show the type of the ASN.1 character string.
1.80 jmc 6527: The type precedes the field contents.

6531: Place spaces round the
6532: .Sq =
6533: character which follows the field name.
6534: .It Cm use_quote
6535: Escape some characters by surrounding the whole string with
6536: .Sq \&"
6537: characters.

6539: .Sq \e
6540: character.
6541: .It Cm utf8
6542: Convert all strings to UTF8 format first, as required by RFC 2253.
6543: On a UTF8 compatible terminal,
6544: the use of this option (and not setting
6545: .Cm esc_msb )
6546: may result in the correct display of multibyte characters.
6547: Usually, multibyte characters larger than 0xff
6548: are represented using the format \eUXXXX for 16 bits and \eWXXXXXXXX
6549: for 32 bits,
6550: and any UTF8Strings are converted to their character form first.

1.80 jmc 6767: behaves like a mini CA.
1.1 jsing 6768: The input file is signed by the CA using this option;
6769: that is, its issuer name is set to the subject name of the CA and it is
6770: digitally signed using the CA's private key.
6771: .Pp
6772: This option is normally combined with the
6773: .Fl req
6774: option.
6775: Without the
6776: .Fl req
6777: option, the input is a certificate which must be self-signed.
6778: .It Fl CAcreateserial
1.80 jmc 6779: Create the CA serial number file if it does not exist
6780: instead of generating an error.
6781: The file will contain the serial number
1.1 jsing 6782: .Sq 02
6783: and the certificate being signed will have
6784: .Sq 1
6785: as its serial number.
1.80 jmc 6786: .It Fl CAform Cm der | pem
1.1 jsing 6787: The format of the CA certificate file.

1.1 jsing 6795: The format of the CA private key.
6796: The default is
1.80 jmc 6797: .Cm pem .
1.1 jsing 6798: .It Fl CAserial Ar file
1.80 jmc 6799: Use the serial number in
6800: .Ar file
6801: to sign a certificate.
6802: The file should consist of one line containing an even number of hex digits
1.1 jsing 6803: with the serial number to use.
6804: After each use the serial number is incremented and written out
6805: to the file again.
6806: .Pp
6807: The default filename consists of the CA certificate file base name with
6808: .Pa .srl
6809: appended.
6810: For example, if the CA certificate file is called
6811: .Pa mycacert.pem ,
6812: it expects to find a serial number file called
6813: .Pa mycacert.srl .
6814: .It Fl checkend Ar arg
6815: Check whether the certificate expires in the next
6816: .Ar arg

6819: otherwise exit with return value 0.
6820: .It Fl clrext
6821: Delete any extensions from a certificate.
6822: This option is used when a certificate is being created from another
6823: certificate (for example with the
6824: .Fl signkey
6825: or the
6826: .Fl CA
6827: options).
6828: Normally, all extensions are retained.
6829: .It Fl days Ar arg
1.80 jmc 6830: The number of days to make a certificate valid for.
1.1 jsing 6831: The default is 30 days.
6832: .It Fl extensions Ar section
6833: The section to add certificate extensions from.
6834: If this option is not specified, the extensions should either be
1.80 jmc 6835: contained in the unnamed (default) section
6836: or the default section should contain a variable called
1.1 jsing 6837: .Qq extensions
6838: which contains the section to use.
6839: .It Fl extfile Ar file
6840: File containing certificate extensions to use.
6841: If not specified, no extensions are added to the certificate.
1.80 jmc 6842: .It Fl keyform Cm der | pem
6843: The format of the private key file used in the
1.1 jsing 6844: .Fl signkey
6845: option.

1.1 jsing 6848: .It Fl set_serial Ar n
1.80 jmc 6849: The serial number to use.
1.1 jsing 6850: This option can be used with either the
6851: .Fl signkey
6852: or
6853: .Fl CA
6854: options.
6855: If used in conjunction with the
6856: .Fl CA
6857: option, the serial number file (as specified by the
6858: .Fl CAserial
6859: or
6860: .Fl CAcreateserial
6861: options) is not used.
6862: .Pp
6863: The serial number can be decimal or hex (if preceded by
6864: .Sq 0x ) .
6865: Negative serial numbers can also be specified but their use is not recommended.
6866: .It Fl signkey Ar file
1.80 jmc 6867: Self-sign
6868: .Ar file
6869: using the supplied private key.
1.1 jsing 6870: .Pp
6871: If the input file is a certificate, it sets the issuer name to the
1.80 jmc 6872: subject name (i.e. makes it self-signed),
1.1 jsing 6873: changes the public key to the supplied value,
6874: and changes the start and end dates.
6875: The start date is set to the current time and the end date is set to
6876: a value determined by the
6877: .Fl days
6878: option.
6879: Any certificate extensions are retained unless the
6880: .Fl clrext
6881: option is supplied.
6882: .Pp
6883: If the input is a certificate request, a self-signed certificate
6884: is created using the supplied private key using the subject name in
6885: the request.
6886: .It Fl x509toreq
1.80 jmc 6887: Convert a certificate into a certificate request.
1.1 jsing 6888: The
6889: .Fl signkey
6890: option is used to pass the required private key.
6891: .El
1.38 jmc 6892: .Sh COMMON NOTATION
6893: Several commands share a common syntax,
6894: as detailed below.

1.33 jmc 6897: .Fl passin
6898: and
6899: .Fl passout
1.38 jmc 6900: for input and output passwords,
6901: allow passwords to be obtained from a variety of sources.
6902: Both of these options take a single argument, described below.
1.33 jmc 6903: If no password argument is given and a password is required,
6904: then the user is prompted to enter one:
6905: this will typically be read from the current terminal with echoing turned off.
