19 .Nd adds identities for the authentication agent
26 adds identities to the authentication agent,
28 When run without arguments, it adds the file
29 .Pa $HOME/.ssh/identity .
30 Alternative file names can be given on the
31 command line. If any file requires a passphrase,
33 asks for the passphrase from the user.
34 The Passphrase it is read from the user's tty.
36 The authentication agent must be running and must be an ancestor of
37 the current process for
41 The options are as follows:
44 Lists fingerprints of all identities currently represented by the agent.
46 Lists public key parameters of all identities currently represented by the agent.
48 Instead of adding the identity, removes the identity from the agent.
50 Deletes all identities from the agent.
54 .It Pa $HOME/.ssh/identity
55 Contains the RSA authentication identity of the user. This file
56 should not be readable by anyone but the user.
59 ignores this file if it is accessible by others.
61 specify a passphrase when generating the key; that passphrase will be
62 used to encrypt the private part of this file. This is the
65 when no other files have been specified.
69 .It Ev "DISPLAY" and "SSH_ASKPASS"
72 needs a passphrase, it will read the passphrase from the current
73 terminal if it was run from a terminal. If
75 does not have a terminal associated with it but
79 are set, it will execute the program specified by
81 and open an X11 window to read the passphrase. This is particularly
86 or related script. (Note that on some machines it

94 is a derivative of the original (free) ssh 1.2.12 release, but with bugs
95 removed and newer features re-added. Rapidly after the 1.2.12 release,
96 newer versions bore successively more restrictive licenses. This version
100 has all components of a restrictive nature (ie. patents, see
102 directly removed from the source code; any licensed or patented components
106 has been updated to support ssh protocol 1.5.
108 contains added support for
110 authentication and ticket passing.
112 supports one-time password authentication with

118 are required for proper operation.
