ssh-add [-lLdD] [file ...]


DESCRIPTION

     ssh-add adds RSA or DSA identities to the authentication agent, ssh-
     agent(1).  When run without arguments, it adds the files
     $HOME/.ssh/id_dsa, $HOME/.ssh/id_rsa, and $HOME/.ssh/identity. Alterna­
     tive file names can be given on the command line.  If any file requires a
     passphrase, ssh-add asks for the passphrase from the user.  The
     Passphrase it is read from the user's tty.  ssh-add retries the last
     passphrase if multiple identity files are given.

     The authentication agent must be running and must be an ancestor of the
     current process for ssh-add to work.

     The options are as follows:

     -l      Lists fingerprints of all identities currently represented by the
             agent.

     -L      Lists public key parameters of all identities currently repre­
             sented by the agent.

     -d      Instead of adding the identity, removes the identity from the
             agent.

     -D      Deletes all identities from the agent.


FILES

     $HOME/.ssh/identity
             Contains the protocol version 1 RSA authentication identity of
             the user.  This file should not be readable by anyone but the us­
             er.  Note that ssh-add ignores this file if it is accessible by
             others.  It is possible to specify a passphrase when generating
             the key; that passphrase will be used to encrypt the private part
             of this file.  This is the default file added by ssh-add when no
             other files have been specified.

     $HOME/.ssh/id_dsa
             Contains the protocol version 2 DSA authentication identity of
             the user.

     $HOME/.ssh/id_rsa
             Contains the protocol version 2 RSA authentication identity of
             the user.


ENVIRONMENT

     DISPLAY and SSH_ASKPASS
             If ssh-add needs a passphrase, it will read the passphrase from
             the current terminal if it was run from a terminal.  If ssh-add
             does not have a terminal associated with it but DISPLAY and
             SSH_ASKPASS are set, it will execute the program specified by
             SSH_ASKPASS and open an X11 window to read the passphrase.  This
             is particularly useful when calling ssh-add from a .Xsession or
             related script.  (Note that on some machines it may be necessary
             to redirect the input from /dev/null to make this work.)
