SYNOPSIS
       openssl srp [-help] [-verbose] [-add] [-modify] [-delete] [-list] [-name section] [-srpvfile file] [-gn identifier]

DESCRIPTION
       This command is deprecated. It is used to maintain an SRP (secure remote password) file. At most one of the -add,
       -modify, -delete, and -list options can be specified.  These options take zero or more usernames as parameters and
       perform the appropriate operation on the SRP file.  For -list, if no user is given then all users are displayed.

       The configuration file to use, and the section within the file, can be specified with the -config and -name flags,
       respectively.
