=head1 DESCRIPTION

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

The configuration file to use, and the section within the file, can be
specified with the B<-config> and B<-name> flags, respectively.
If the config file is not specified, the B<-srpvfile> can be used to
just specify the file to operate on.

The B<-userinfo> option specifies additional information to add when
adding or modifying a user.

The B<-gn> flag specifies the B<g> and B<N> values, using one of
the strengths defined in IETF RFC 5054.

The B<-passin> and B<-passout> arguments are parsed as described in
the L<openssl(1)> command.
