SYNOPSIS
     ssh-add [-lLdD] [file ...]
     ssh-add -s reader
     ssh-add -e reader

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 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  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 repreM--
             sented by the agent.

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

     -D      Deletes all identities from the agent.

     -s reader
             Add key in smartcard reader.

     -e reader
             Remove key in smartcard reader.

FILES
     $HOME/.ssh/identity
             Contains the protocol version 1  RSA  authentication
identity of
             the  user.  This file should not be readable by any-
one but the
             user.  Note that ssh-add ignores this file if it  is
accessible by
             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 DIS-
PLAY 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.)
