NÁZOV
     ssh-add – pridá RSA alebo DSA identity do agenta na overenie totožnosti

SYNTAX
     ssh-add [-cDdLlXx] [-t life] [file ...]
     ssh-add -s pkcs11
     ssh-add -e pkcs11POPIS
     ssh-add pridá RSA alebo DSA identity do agenta na overenie totožnosti
     ssh-agent(1).  Keď je program spustený bez parametrov, pridá súbory 
     ~/.ssh/id_rsa, ~/.ssh/id_dsa and ~/.ssh/identity.  Po načítaní súkromného 
     kľúča sa ssh-add pokúsi načítať informácie o certifikáte zo súboru
     s rovnakým menom, ako má súkromný kľúč, ku ktorému pridá koncovku
     -cert.pub. Alternatívne názvy súborov môžu byť zadané ako parameter 
     do príkazového riadka.

     Ak niektorý súbor vyžaduje zadanie vstupnej frázy, príkaz ssh-add si
     vyžiada vstupnú frázu od používateľa. Vstupná fráza sa načíta 
     z používateľovej tty konzoly. Program ssh-add sa pokúsi použiť poslednú 
     vstupnú frázu ak má spracovať viacero identít.

     Aby program ssh-add správne pracoval, musí byť spustený agent na overenie
     totožnosti a premenná prostredia SSH_AUTH_SOCK musí obsahovať názov 
     soketu.

     Voľby príkazu sú nasledovné::

     -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
             confirmation is signaled by a zero exit status from the
             SSH_ASKPASS program, rather than text entered into the requester.

     -D      Deletes all identities from the agent.

     -d      Instead of adding identities, removes identities from the agent.
             If ssh-add 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, ssh-add will append .pub and retry.

     -e pkcs11
             Remove keys provided by the PKCS#11 shared library pkcs11.

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

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

     -s pkcs11
             Add keys provided by the PKCS#11 shared library pkcs11.

     -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_config(5).

     -X      Unlock the agent.

     -x      Lock the agent with a password.

PROSTREDIE
     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.

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

AUTORI
      OpenSSH je odvodenina od pôvodnej slobodnej verzie ssh 1.2.12, ktorú vydal
     Tatu Ylonen.  Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo
     de Raadt a Dug Song odstránili mnoho chýb, pridali novšie funkcie a
     vytvorili OpenSSH.  Markus Friedl prispel podporou SSH protokolov verzií
     1.5 a 2.0.
