NAME

      ssh-add - adds RSA or DSA identities to the authentication agent

SYNOPSIS

      ssh-add [-cDdLlXx] [-t life] [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 files
      ~/.ssh/id_rsa, ~/.ssh/id_dsa and ~/.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 the SSH_AUTH_SOCK environ‐
      ment variable must contain the name of its socket for ssh-add to work.
 
      The options are as follows:
 
      -c      Indicates that added identities should be subject to confirmation
              before being used for authentication.  Confirmation is performed
              by the SSH_ASKPASS program mentioned below.  Successful confirma‐
              tion is signaled by a zero exit status from the SSH_ASKPASS pro‐
              gram, rather than text entered into the requester.
 
      -D      Deletes all identities from the agent.
 
      -d      Instead of adding the identity, removes the identity from the
              agent.
 
      -e reader
              Remove key in smartcard reader.
 
      -L      Lists public key parameters of all identities currently repre‐
              sented by the agent.
 
      -l      Lists fingerprints of all identities currently represented by the
              agent.
 
      -s reader
              Add key in smartcard reader.
 
      -t life
              Set a maximum lifetime when adding identities to an agent.  The
              lifetime may be specified in seconds or in a time format speci‐
              fied in sshd_config(5).
 
      -X      Unlock the agent.
 
      -x      Lock the agent with a password.

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.)
 
      SSH_AUTH_SOCK
              Identifies the path of a unix-domain socket used to communicate
              with the agent.

FILES

      ~/.ssh/identity
              Contains the protocol version 1 RSA authentication identity of
              the user.
 
      ~/.ssh/id_dsa
              Contains the protocol version 2 DSA authentication identity of
              the user.
 
      ~/.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.

DIAGNOSTICS

      Exit status is 0 on success, 1 if the specified command fails, and 2 if
      ssh-add is unable to contact the authentication agent.
      ssh(1), ssh-agent(1), ssh-keygen(1), sshd(8)
