1.2 deraadt 51: .Nm
1.14 markus 52: adds RSA or DSA identities to the authentication agent,
1.2 deraadt 53: .Xr ssh-agent 1 .
1.1 deraadt 54: When run without arguments, it adds the file
1.2 deraadt 55: .Pa $HOME/.ssh/identity .
1.11 aaron 56: Alternative file names can be given on the command line.
57: If any file requires a passphrase,
1.2 deraadt 58: .Nm
1.12 aaron 59: asks for the passphrase from the user.
1.11 aaron 60: The Passphrase it is read from the user's tty.
1.2 deraadt 61: .Pp
1.1 deraadt 62: The authentication agent must be running and must be an ancestor of
63: the current process for
1.2 deraadt 64: .Nm
1.1 deraadt 65: to work.
1.2 deraadt 66: .Pp
67: The options are as follows:
68: .Bl -tag -width Ds
69: .It Fl l
1.7 markus 70: Lists fingerprints of all identities currently represented by the agent.
71: .It Fl L
72: Lists public key parameters of all identities currently represented by the agent.
1.2 deraadt 73: .It Fl d
1.1 deraadt 74: Instead of adding the identity, removes the identity from the agent.
1.2 deraadt 75: .It Fl D
1.1 deraadt 76: Deletes all identities from the agent.

78: .Sh FILES
79: .Bl -tag -width Ds
1.9 markus 80: .It Pa $HOME/.ssh/identity
1.11 aaron 81: Contains the RSA authentication identity of the user.
82: This file should not be readable by anyone but the user.
1.4 markus 83: Note that
84: .Nm
85: ignores this file if it is accessible by others.
86: It is possible to
1.1 deraadt 87: specify a passphrase when generating the key; that passphrase will be
1.11 aaron 88: used to encrypt the private part of this file.
89: This is the default file added by
1.2 deraadt 90: .Nm
1.1 deraadt 91: when no other files have been specified.
1.14 markus 92: .It Pa $HOME/.ssh/id_dsa
93: Contains the DSA authentication identity of the user.

1.1 deraadt 98: If
1.2 deraadt 99: .Nm
1.1 deraadt 100: needs a passphrase, it will read the passphrase from the current
1.11 aaron 101: terminal if it was run from a terminal.
102: If
1.2 deraadt 103: .Nm
1.1 deraadt 104: does not have a terminal associated with it but
1.2 deraadt 105: .Ev DISPLAY
1.8 markus 106: and
107: .Ev SSH_ASKPASS
108: are set, it will execute the program specified by
109: .Ev SSH_ASKPASS
1.11 aaron 110: and open an X11 window to read the passphrase.
111: This is particularly useful when calling
1.2 deraadt 112: .Nm
113: from a
114: .Pa .Xsession
1.11 aaron 115: or related script.
116: (Note that on some machines it
1.2 deraadt 117: may be necessary to redirect the input from
118: .Pa /dev/null
119: to make this work.)
