OpenSolaris 2009.06 - man page for ssh-add (opensolaris section 1)

ssh-add(1)				  User Commands 			       ssh-add(1)

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

SYNOPSIS
       ssh-add [-lLdDxX] [-t life] [ file ]...

DESCRIPTION
       The  ssh-add utility adds RSA or DSA identities to the authentication agent, ssh-agent(1).
       When run without arguments, it attempts to add all of the files	$HOME/.ssh/identity  (RSA
       v1),  $HOME/.ssh/id_rsa	(RSA v2), and $HOME/.ssh/id_dsa (DSA v2) that exist. If more than
       one of the private keys exists, an attempt to decrypt each with the same  passphrase  will
       be  made  before  reprompting  for a different passphrase. The passphrase is read from the
       user's tty or by running the program defined in SSH_ASKPASS (see below).

       The authentication agent must be running.

OPTIONS
       The following options are supported:

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

       -D	  Deletes all identities from the agent.

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

       -L	  Lists  public  key  parameters  of  all identities currently represented by the
		  agent.

       -t life	  Sets a maximum lifetime when adding identities to an agent. The lifetime may be
		  specified in seconds or in a time format specified in sshd(1M).

       -x	  Locks the agent with a password.

       -X	  Unlocks the agent.

ENVIRONMENT VARIABLES
       DISPLAY		If  ssh-add needs a passphrase, it will read the passphrase from the cur-
       SSH_ASKPASS	rent 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.

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

EXIT STATUS
       The following exit values are returned:

       0    Successful completion.

       1    An error occurred.

FILES
       These  files  should not be readable by anyone but the user. Notice that ssh-add ignores a
       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.

       If  these  files are stored on a network file system it is assumed that either the protec-
       tion provided in the file themselves or the transport layer of  the  network  file  system
       provides  sufficient  protection  for the site policy. If this is not the case, then it is
       recommended the key files are stored on removable media or locally on the relevant hosts.

       Recommended names for the DSA and RSA key files:

       $HOME/.ssh/identity	  Contains the RSA authentication identity of the user for proto-
				  col version 1.

       $HOME/.ssh/identity.pub	  Contains  the public part of the RSA authentication identity of
				  the user for protocol version 1.

       $HOME/.ssh/id_dsa	  Contains the private DSA authentication identity of the user.

       $HOME/.ssh/id_dsa.pub	  Contains the public part of the DSA authentication identity  of
				  the user.

       $HOME/.ssh/id_rsa	  Contains the private RSA authentication identity of the user.

       $HOME/.ssh/id_rsa.pub	  Contains  the public part of the RSA authentication identity of
				  the user.
