NAME
       srptool - GnuTLS SRP tool

SYNOPSIS
       srptool [-flags] [-flag [value]] [--option-name[[=| ]value]]

       All arguments must be options.


DESCRIPTION
       Simple  program  that emulates the programs in the Stanford SRP (Secure
       Remote Password) libraries using GnuTLS.  It is  intended  for  use  in
       places  where  you  don't  expect SRP authentication to be the used for
       system users.

       In  brief,  to use SRP you need to create  two  files.  These  are  the
       password  file  that  holds the users and the verifiers associated with
       them  and  the configuration file to hold the group parameters  (called
       tpasswd.conf).

OPTIONS
       -d number, --debug=number
              Enable  debugging.   This  option takes an integer number as its
              argument.  The value of number is constrained to being:
                  in the range  0 through 9999

              Specifies the debug level.

       -i number, --index=number
              specify the index of the group parameters in tpasswd.conf to
              use.  This option takes an integer number as its argument.  The
              default number for this option is:
                   1


       -u string, --username=string
              specify a username.


       -p string, --passwd=string
              specify a password file.


       -s number, --salt=number
              specify salt size.  This option takes an integer number as its
              argument.


       --verify
              just verify the password..

              Verifies the password provided against the password file.

       -v string, --passwd-conf=string
              specify a password conf file..

              Specify a filename or a PKCS #11 URL to read the CAs from.

       --create-conf=string
              Generate a password configuration file..

              This generates a password configuration file (tpasswd.conf) con-
              taining the required for TLS parameters.

       -h, --help
              Display usage information and exit.

       -!, --more-help
              Pass the extended usage information through a pager.

       -v [{v|c|n --version [{v|c|n}]}]
              Output version of program and exit.  The default mode is `v', a
              simple version.  The `c' mode will print copyright information
              and `n' will print the full copyright notice.

EXAMPLES
       To create tpasswd.conf which holds the g and n values for SRP protocol
       (generator and a large prime), run:
           $ srptool --create-conf /etc/tpasswd.conf

       This command will create /etc/tpasswd and will add user 'test' (you
       will also be prompted for a password). Verifiers are stored by default
       in the way libsrp expects.
           $ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf -u test


       This command will check against a password. If the password matches the
       one in /etc/tpasswd you will get an ok.
           $ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf --verify -u test

EXIT STATUS
       One of the following exit values will be returned:

       0  (EXIT_SUCCESS)
              Successful program execution.

       1  (EXIT_FAILURE)
              The operation failed or the command syntax was not valid.

       70  (EX_SOFTWARE)
              libopts had an internal operational error.  Please report it to
              autogen-users@lists.sourceforge.net.  Thank you.
