SYNOPSIS
     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 file
     $HOME/.ssh/identity. Alternative 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.

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

     The options are as follows:

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

     -L       Lists  public key parameters of all identities cur-
rently 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 RSA authentication identity of the us-
er.  This file
             should not be readable by anyone but the user.  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

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.)

     OpenSSH is a derivative of the original  (free)  ssh  1.2.12
release, but
     with  bugs removed and newer features re-added.  Rapidly af-
ter the 1.2.12
     release, newer versions bore successively  more  restrictive
licenses.
     This version of OpenSSH

     o    has  all  components  of  a  restrictive  nature (i.e.,
patents, see
         crypto(3))  directly removed from the source  code;  any
licensed or
         patented  components are chosen from external libraries.

     o   has been updated to support ssh protocol 1.5.

     o   contains added support  for  kerberos(8)  authentication
and ticket
         passing.

     o    supports one-time password authentication with skey(1).
