Damien Millerad833b32000-08-23 10:46:23 +1000[diff] [blame]56adds RSA or DSA identities to the authentication agent,
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]57.Xr ssh-agent 1 .
58When run without arguments, it adds the file
59.Pa $HOME/.ssh/identity .
Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]60Alternative file names can be given on the command line.
61If any file requires a passphrase,
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]62.Nm
Damien Miller22c77262000-04-13 12:26:34 +1000[diff] [blame]63asks for the passphrase from the user.
Ben Lindstromaafff9c2001-05-06 03:01:02 +0000[diff] [blame]64The passphrase is read from the user's tty.
Ben Lindstrom12de6162001-04-10 02:46:54 +0000[diff] [blame]65.Nm
66retries the last passphrase if multiple identity files are given.
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]67.Pp
68The authentication agent must be running and must be an ancestor of
69the current process for

78Lists public key parameters of all identities currently represented by the agent.
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]79.It Fl d
80Instead of adding the identity, removes the identity from the agent.
81.It Fl D
82Deletes all identities from the agent.
