=head1 DESCRIPTION
|
|
|
|
The SRP functions described on this page are used to calculate various
|
|
parameters and keys used by SRP as defined in RFC2945. The server key and I<B>
|
|
and I<u> parameters are used on the server side and are calculated via
|
|
SRP_Calc_server_key(), SRP_Calc_B_ex(), SRP_Calc_B(), SRP_Calc_u_ex() and
|
|
SRP_Calc_u(). The client key and B<x> and B<A> parameters are used on the
|
|
client side and are calculated via the functions SRP_Calc_client_key_ex(),
|
|
SRP_Calc_client_key(), SRP_Calc_x_ex(), SRP_Calc_x() and SRP_Calc_A(). See
|
|
RFC2945 for a detailed description of their usage and the meaning of the various
|
|
BIGNUM parameters to these functions.
|
|
|
|
Most of these functions come in two forms. Those that take a I<libctx> and
|
|
I<propq> parameter, and those that don't. Any cryptogrpahic functions that
|
|
are fetched and used during the calculation use the provided I<libctx> and
|
|
I<propq>. See L<provider(7)/Fetching algorithms> for more details. The variants
|
|
that do not take a I<libctx> and I<propq> parameter use the default library
|
|
context and property query string. The SRP_Calc_server_key() and SRP_Calc_A()
|
|
functions do not have a form that takes I<libctx> or I<propq> parameters because
|
|
they do not need to fetch any cryptographic algorithms.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
All these functions return the calculated key or parameter, or NULL on error.
