It is used to maintain an SRP (secure remote 31password) file. At most one of the B<-add>, B<-modify>, B<-delete>, and B<-list> 32options can be specified. 33These options take zero or more usernames as parameters and perform the 34appropriate operation on the SRP file. 35For B<-list>, if no I<user> is given then all users are displayed. 36 37The configuration file to use, and the section within the file, can be 38specified with the B<-config> and B<-name> flags, respectively. 39 40=head1 OPTIONS 41 42=over 4 43 44=item B<-help> 45 46Display an option summary. 47 48=item B<-verbose> 49 50Generate verbose output while processing. 51 52=item B<-add> 53 54Add a user and SRP verifier. 55 56=item B<-modify> 57 58Modify the SRP verifier of an existing user. 59 60=item B<-delete> 61 62Delete user from verifier file. 63 64=item B<-list> 65 66List users. 67 68=item B<-name> 69 70The particular SRP definition to use. 71 72=item B<-srpvfile> I<file> 73 74If the config file is not specified, 75B<-srpvfile> can be used to specify the file to operate on. 76 77=item B<-gn> 78 79Specifies the B<g> and B<N> values, using one of 80the strengths defined in IETF RFC 5054. 81 82=item B<-userinfo> 83 84specifies additional information to add when 85adding or modifying a user. 86 87=item B<-passin> I<arg>, B<-passout> I<arg> 88 89The password source for the input and output file. 90For more information about the format of B<arg> 91see L<openssl-passphrase-options(1)>. 92 93{- $OpenSSL::safe::opt_engine_item -} 94 95{- $OpenSSL::safe::opt_r_item -} 96 97{- $OpenSSL::safe::opt_provider_item -} 98 99{- $OpenSSL::safe::opt_config_item -} 100 101{- $OpenSSL::safe::opt_r_synopsis -} 102 103=back 104 105=head1 HISTORY 106 107The B<-engine> option was deprecated in OpenSSL 3.0. 108 109=head1 COPYRIGHT 110 111Copyright 2017-2021 The OpenSSL Project Authors.
