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 files
     $HOME/.ssh/id_rsa, $HOME/.ssh/id_dsa 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 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.

     -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.

     $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.

     Identity files should not be readable by anyone but the user.  Note that
     ssh-add ignores identity files if they are accessible by others.

ENVIRONMENT

     DISPLAY and SSH_ASKPASS
     OpenSSH is a derivative of the original and free ssh 1.2.12 release by
     Tatu Ylonen.  Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo
     de Raadt and Dug Song removed many bugs, re-added newer features and cre-
     ated OpenSSH.  Markus Friedl contributed the support for SSH protocol
     versions 1.5 and 2.0.
