  .Pp
  The
  .Nm pkcs8
! command processes private keys in PKCS#8 format.
! It can handle both unencrypted PKCS#8 PrivateKeyInfo format
! and EncryptedPrivateKeyInfo format with a variety of PKCS#5
! .Pq v1.5 and v2.0
! and PKCS#12 algorithms.
  .Pp
  The options are as follows:
  .Bl -tag -width Ds
  .It Fl embed
! This option generates DSA keys in a broken format.
! The DSA parameters are embedded inside the
! .Em PrivateKey
! structure.
  In this form the OCTET STRING contains an ASN1 SEQUENCE consisting of
  two structures:
  a SEQUENCE containing the parameters and an ASN1 INTEGER containing
  the private key.
  .It Fl in Ar file
! This specifies the input
! .Ar file
! to read a key from, or standard input if this option is not specified.
  If the key is encrypted, a pass phrase will be prompted for.
! .It Fl inform Ar DER | PEM
! This specifies the input format.
  If a PKCS#8 format key is expected on input,
  then either a
  DER- or PEM-encoded version of a PKCS#8 key will be expected.
  Otherwise the DER or PEM format of the traditional format private key is used.
  .It Fl nocrypt
! PKCS#8 keys generated or input are normally PKCS#8
! .Em EncryptedPrivateKeyInfo
! structures using an appropriate password-based encryption algorithm.
! With this option, an unencrypted
! .Em PrivateKeyInfo
! structure is expected or output.
! This option does not encrypt private keys at all and should only be used
! when absolutely necessary.
! Certain software such as some versions of Java code signing software use
! unencrypted private keys.
  .It Fl noiter
  Use an iteration count of 1.
  See the
  .Sx PKCS12
  section below for a detailed explanation of this option.
  .It Fl nooct
! This option generates RSA private keys in a broken format that some software
! uses.
  Specifically the private key should be enclosed in an OCTET STRING,
  but some software just includes the structure itself without the
  surrounding OCTET STRING.
  .It Fl nsdb
! This option generates DSA keys in a broken format compatible with Netscape
  private key databases.
! The
! .Em PrivateKey
! contains a SEQUENCE consisting of the public and private keys, respectively.
  .It Fl out Ar file
! This specifies the output
! .Ar file
! to write a key to, or standard output by default.
  If any encryption options are set, a pass phrase will be prompted for.
! The output filename should
! .Em not
! be the same as the input filename.
! .It Fl outform Ar DER | PEM
! This specifies the output format; the options have the same meaning as the
! .Fl inform
! option.
  .It Fl passin Ar arg
  The key password source.
  .It Fl passout Ar arg
  The output file password source.
  .It Fl topk8
! Normally, a PKCS#8 private key is expected on input and a traditional format
! private key will be written.
! With the
! .Fl topk8
! option the situation is reversed:
! it reads a traditional format private key and writes a PKCS#8 format key.
  .It Fl v1 Ar alg
! This option specifies a PKCS#5 v1.5 or PKCS#12 algorithm to use.
! A complete list of possible algorithms is included below.
! .It Fl v2 Ar alg
! This option enables the use of PKCS#5 v2.0 algorithms.
! Normally, PKCS#8 private keys are encrypted with the password-based
! encryption algorithm called
! .Em pbeWithMD5AndDES-CBC ;
! this uses 56-bit DES encryption but it was the strongest encryption
! algorithm supported in PKCS#5 v1.5.
! Using the
! .Fl v2
! option PKCS#5 v2.0 algorithms are used which can use any
! encryption algorithm such as 168-bit triple DES or 128-bit RC2, however
! not many implementations support PKCS#5 v2.0 yet.
! If using private keys with
! .Nm OpenSSL
! then this doesn't matter.
  .Pp
- The
- .Ar alg
- argument is the encryption algorithm to use; valid values include
- .Ar des , des3 ,
- and
- .Ar rc2 .
- It is recommended that
- .Ar des3
- is used.
- .El
- .Sh PKCS8 NOTES
- The encrypted form of a PEM-encoded PKCS#8 file uses the following
- headers and footers:
- .Bd -unfilled -offset indent
- -----BEGIN ENCRYPTED PRIVATE KEY-----
- -----END ENCRYPTED PRIVATE KEY-----
- .Ed
- .Pp
- The unencrypted form uses:
- .Bd -unfilled -offset indent
- -----BEGIN PRIVATE KEY-----
- -----END PRIVATE KEY-----
- .Ed
- .Pp
- Private keys encrypted using PKCS#5 v2.0 algorithms and high iteration
- counts are more secure than those encrypted using the traditional
- .Nm SSLeay
- compatible formats.
- So if additional security is considered important, the keys should be converted.
- .Pp
- The default encryption is only 56 bits because this is the encryption
- that most current implementations of PKCS#8 support.
- .Pp
- Some software may use PKCS#12 password-based encryption algorithms
- with PKCS#8 format private keys: these are handled automatically
- but there is no option to produce them.
- .Pp
- It is possible to write out
- DER-encoded encrypted private keys in PKCS#8 format because the encryption
- details are included at an ASN1
- level whereas the traditional format includes them at a PEM level.
- .Sh PKCS#5 V1.5 AND PKCS#12 ALGORITHMS
- Various algorithms can be used with the
- .Fl v1
- command line option, including PKCS#5 v1.5 and PKCS#12.
- These are described in more detail below.
- .Pp
  .Bl -tag -width "XXXX" -compact
! .It Ar PBE-MD5-DES
! These algorithms were included in the original PKCS#5 v1.5 specification.
! They only offer 56 bits of protection since they both use DES.
! .Pp
! .It Ar PBE-SHA1-RC2-64 | PBE-MD5-RC2-64 | PBE-SHA1-DES
! These algorithms are not mentioned in the original PKCS#5 v1.5 specification
! but they use the same key derivation algorithm and are supported by some
! software.
! They are mentioned in PKCS#5 v2.0.
! They use either 64-bit RC2 or 56-bit DES.
! .Pp
! .It Ar PBE-SHA1-RC4-128 | PBE-SHA1-RC4-40 | PBE-SHA1-3DES | PBE-SHA1-2DES
! .It Ar PBE-SHA1-RC2-128 | PBE-SHA1-RC2-40
! These algorithms use the PKCS#12 password-based encryption algorithm and
! allow strong encryption algorithms like triple DES or 128-bit RC2 to be used.
  .El
! .Sh PKCS8 EXAMPLES
! Convert a private key from traditional to PKCS#5 v2.0 format using triple DES:
  .Pp
! .Dl "$ openssl pkcs8 -in key.pem -topk8 -v2 des3 -out enckey.pem"
! .Pp
! Convert a private key to PKCS#8 using a PKCS#5 1.5 compatible algorithm
! .Pq DES :
! .Pp
! .Dl $ openssl pkcs8 -in key.pem -topk8 -out enckey.pem
! .Pp
! Convert a private key to PKCS#8 using a PKCS#12 compatible algorithm
! .Pq 3DES :
! .Bd -literal -offset indent
! $ openssl pkcs8 -in key.pem -topk8 -out enckey.pem \e
! 	-v1 PBE-SHA1-3DES
! .Ed
! .Pp
! Read a DER-unencrypted PKCS#8 format private key:
! .Pp
! .Dl "$ openssl pkcs8 -inform DER -nocrypt -in key.der -out key.pem"
! .Pp
! Convert a private key from any PKCS#8 format to traditional format:
! .Pp
! .Dl $ openssl pkcs8 -in pk8.pem -out key.pem
! .Sh PKCS8 STANDARDS
! Test vectors from this PKCS#5 v2.0 implementation were posted to the
! pkcs-tng mailing list using triple DES, DES and RC2 with high iteration counts;
! several people confirmed that they could decrypt the private
! keys produced and therefore it can be assumed that the PKCS#5 v2.0
! implementation is reasonably accurate at least as far as these
! algorithms are concerned.
! .Pp
! The format of PKCS#8 DSA
! .Pq and other
! private keys is not well documented:
! it is hidden away in PKCS#11 v2.01, section 11.9;
! .Nm OpenSSL Ns Li 's
! default DSA PKCS#8 private key format complies with this standard.
! .Sh PKCS8 BUGS
! There should be an option that prints out the encryption algorithm
! in use and other details such as the iteration count.
! .Pp
! PKCS#8 using triple DES and PKCS#5 v2.0 should be the default private
! key format; for
! .Nm OpenSSL
! compatibility, several of the utilities use the old format at present.
