SSH-KEYGEN2(1)                 SSH2                SSH-KEYGEN2(1)

NAME
       ssh-keygen2 - authentication key pair generation

SYNOPSIS
       ssh-keygen2   [-b bits]   [-t key_algorithm]   [   -c com-
       ment_string] [ -e file] [ -p passphrase] [ -P ] [ -l file]
       [  -o output_file]  [ -v ] [ -h ] [ -\?  ] [ -q ] [ -r ] [
       -i ] [key1 key2 ...]

DESCRIPTION
       ssh-keygen2 generates and manages authentication keys  for
       ssh2(1).  Normally each user wishing to use ssh2 with pub-
       lic key authentication runs this to create  authentication
       keys.  Additionally, the system administrator may use this
       to generate host keys for sshd2(8).

OPTIONS
       -b bits
              Length of the key in bits, for example 1024 bits.

       -t key_algorithm
              The algorithm used  in  key  generation.  Currently
              only DSS (Digital Signature Standard) is supported.
              (in some distributions, RSA is, too)

       -c comment_string
              Specify the key's comment string.

       -e file
              Edit specified key. Makes ssh-keygen2  interactive.
              You can change the key's passphrase or comment.

       -p passphrase
              Specify the passphrase used.

       -P     Specify  that  key  will  be  saved  with  an empty
              passphrase.

       -l file
              Convert key from ssh1 format to ssh2 format.

       -o output_file
              Specify the output filename used.

       -v     Print version string and exit.

       -h | -\?
              Print a short summary of ssh-keygen2 commands.

       -q     Hide the progress indicator.

       -r     Stir in data from stdin to the random pool.

       -i     Display (all) information about  a  key.  (not  yet
              implemented)

FILES
       $HOME/.ssh2/random_seed
              Used for seeding the random number generator.  This
              file should not be readable by anyone but the user.
              This  file is created the first time the program is
              run, and is updated every time.

       $HOME/.ssh2/id_KEYTYPE_KEYLEN_X
              Private authentication keys.

       $HOME/.ssh2/id_KEYTYPE_KEYLEN_X.pub
              Public authentication keys.

       /etc/ssh2/hostkey

       /etc/ssh2/hostkey.pub
              Private and public sshd2(8) host keys.
