The documentation on algorithm fetching has moved. There were a lot of references to the old location so we update all of those locations. Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/1487)

=head1 DESCRIPTION
|
|
|
|
All of the functions described on this page are deprecated. There are no
|
|
available replacement functions at this time.
|
|
|
|
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<crypto(7)/ALGORITHM FETCHING> 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.

=head1 HISTORY
|
|
|
|
SRP_Calc_B_ex, SRP_Calc_u_ex, SRP_Calc_client_key_ex and SRP_Calc_x_ex were
|
|
introduced in OpenSSL 3.0.
|
|
|
|
All of the other functions were added in OpenSSL 1.0.1.
|
|
|
|
All of these functions were deprecated in OpenSSL 3.0.
