19 .Nd adds RSA identities for the authentication agent
26 adds RSA 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 command line.
31 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.
56 This file 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.
63 This is the default file added by
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.
76 does not have a terminal associated with it but
80 are set, it will execute the program specified by
82 and open an X11 window to read the passphrase.

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