NAME
     sssshh-aadddd - adds RSA or DSA identities to the authentication agent

SYNOPSIS
     sssshh-aadddd [-ccDDddLLllXXxxKKkk] [-tt life] [file ...]
     sssshh-aadddd -ss reader
     sssshh-aadddd -ee reader

DESCRIPTION
     sssshh-aadddd adds RSA or DSA identities to the authentication agent,
     ssh-agent(1).  When run without arguments, it adds the files
     ~/.ssh/idrsa, ~/.ssh/iddsa and ~/.ssh/identity.  Alternative file names
     can be given on the command line.  If any file requires a passphrase,
     sssshh-aadddd asks for the passphrase from the user.  The passphrase is read
     from the user's tty.  sssshh-aadddd retries the last passphrase if multiple
     identity files are given.

     The authentication agent must be running and the SSHAUTHSOCK environ-
     ment variable must contain the name of its socket for sssshh-aadddd to work.

     The options are as follows:

     -cc      Indicates that added identities should be subject to confirmation
             before being used for authentication.  Confirmation is performed
             by the SSHASKPASS program mentioned below.  Successful confirma-
             tion is signaled by a zero exit status from the SSHASKPASS pro-
             gram, rather than text entered into the requester.

     -DD      Deletes all identities from the agent.

     -dd      Instead of adding identities, removes identities from the agent.
             If sssshh-aadddd has been run without arguments, the keys for the
             default identities will be removed.  Otherwise, the argument list
             will be interpreted as a list of paths to public key files and
             matching keys will be removed from the agent.  If no public key
             is found at a given path, sssshh-aadddd will append .pub and retry.

     -ee reader
             Remove key in smartcard reader.

     -LL      Lists public key parameters of all identities currently repre-
             sented by the agent.

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

     -ss reader
             Add key in smartcard reader.

     -tt 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 sshdconfig(5).

     -XX      Unlock the agent.

     -xx      Lock the agent with a password.

     -KK      When adding identities, each passphrase will also be stored in
             your keychain.  When removing identities with -d, each passphrase
             will be removed from your keychain.

     -kk      Add identities to the agent using any passphrases stored in your
             keychain.

ENVIRONMENT     DISPLAY and SSHASKPASS
             If sssshh-aadddd needs a passphrase, it will read the passphrase from
             the current terminal if it was run from a terminal.  If sssshh-aadddd
             does not have a terminal associated with it but DISPLAY and
             SSHASKPASS are set, it will execute the program specified by
             SSHASKPASS and open an X11 window to read the passphrase.  This
             is particularly useful when calling sssshh-aadddd 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.)

     SSHAUTHSOCK
             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/iddsa
             Contains the protocol version 2 DSA authentication identity of
             the user.

     ~/.ssh/idrsa
             Contains the protocol version 2 RSA authentication identity of
             the user.

     Identity files should not be readable by anyone but the user.  Note that
     sssshh-aadddd 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
     sssshh-aadddd is unable to contact the authentication agent.
