NAME

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

SYNOPSIS

     ssh-add [-lLdDxX] [-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
     $HOME/.ssh/id_rsa, $HOME/.ssh/id_dsa and $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 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 represented by the agent.

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

     -D      Deletes all identities from the agent.

     -x      Lock the agent with a password.

     -X      Unlock the agent.

     -t life
	     Set a maximum lifetime when adding identities to an agent.  The lifetime may be specified in seconds or in a time format specified in
	     sshd(8).

     -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
	     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.

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.

AUTHORS

     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 created OpenSSH.  Markus Friedl contributed the support for SSH
     protocol versions 1.5 and 2.0.
