f54651ce | 50 | .Sh DESCRIPTION |
bf740959 | 51 | .Nm |
2e73a022 | 52 | adds RSA or DSA identities to the authentication agent, |
bf740959 | 53 | .Xr ssh-agent 1 . |
54 | When run without arguments, it adds the file | |
55 | .Pa $HOME/.ssh/identity . | |
4fe2af09 | 56 | Alternative file names can be given on the command line. |
57 | If any file requires a passphrase, | |
bf740959 | 58 | .Nm |
f54651ce | 59 | asks for the passphrase from the user. |
4fe2af09 | 60 | The Passphrase it is read from the user's tty. |
49ae4185 | 61 | .Nm |
62 | retries the last passphrase if multiple identity files are given. | |
bf740959 | 63 | .Pp |
64 | The authentication agent must be running and must be an ancestor of | |
65 | the current process for | |
66 | .Nm | |
67 | to work. | |
68 | .Pp | |
69 | The options are as follows: | |
70 | .Bl -tag -width Ds | |
71 | .It Fl l | |
f095fcc7 | 72 | Lists fingerprints of all identities currently represented by the agent. |
73 | .It Fl L | |
74 | Lists public key parameters of all identities currently represented by the agent. | |
bf740959 | 75 | .It Fl d |
76 | Instead of adding the identity, removes the identity from the agent. | |
77 | .It Fl D | |
78 | Deletes all identities from the agent. | |
79 | .El | |
80 | .Sh FILES | |
81 | .Bl -tag -width Ds | |
57112b5a | 82 | .It Pa $HOME/.ssh/identity |
c0ecc314 | 83 | Contains the protocol version 1 RSA authentication identity of the user. |
4fe2af09 | 84 | This file should not be readable by anyone but the user. |
bf740959 | 85 | Note that |
86 | .Nm | |
87 | ignores this file if it is accessible by others. | |
88 | It is possible to | |
89 | specify a passphrase when generating the key; that passphrase will be | |
4fe2af09 | 90 | used to encrypt the private part of this file. |
91 | This is the default file added by | |
bf740959 | 92 | .Nm |
93 | when no other files have been specified. | |
2e73a022 | 94 | .It Pa $HOME/.ssh/id_dsa |
c0ecc314 | 95 | Contains the protocol version 2 DSA authentication identity of the user. |
96 | .It Pa $HOME/.ssh/id_rsa | |
97 | Contains the protocol version 2 RSA authentication identity of the user. | |

101 | .It Ev "DISPLAY" and "SSH_ASKPASS" | |
bf740959 | 102 | If |
103 | .Nm | |
104 | needs a passphrase, it will read the passphrase from the current | |
4fe2af09 | 105 | terminal if it was run from a terminal. |
106 | If | |
bf740959 | 107 | .Nm |
108 | does not have a terminal associated with it but | |
109 | .Ev DISPLAY | |
aa3378df | 110 | and |
111 | .Ev SSH_ASKPASS | |
112 | are set, it will execute the program specified by | |
113 | .Ev SSH_ASKPASS | |
4fe2af09 | 114 | and open an X11 window to read the passphrase. |
115 | This is particularly useful when calling | |
bf740959 | 116 | .Nm |
117 | from a | |
118 | .Pa .Xsession | |
4fe2af09 | 119 | or related script. |
120 | (Note that on some machines it | |
bf740959 | 121 | may be necessary to redirect the input from |
122 | .Pa /dev/null | |
123 | to make this work.) | |
