.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
All of the functions described on this page are deprecated. There are no
available replacement functions at this time.
.PP
The \s-1SRP\s0 functions described on this page are used to calculate various
parameters and keys used by \s-1SRP\s0 as defined in \s-1RFC2945.\s0 The server key and \fIB\fR
and \fIu\fR parameters are used on the server side and are calculated via
\&\fBSRP_Calc_server_key()\fR, \fBSRP_Calc_B_ex()\fR, \fBSRP_Calc_B()\fR, \fBSRP_Calc_u_ex()\fR and
\&\fBSRP_Calc_u()\fR. The client key and \fBx\fR and \fBA\fR parameters are used on the
client side and are calculated via the functions \fBSRP_Calc_client_key_ex()\fR,
\&\fBSRP_Calc_client_key()\fR, \fBSRP_Calc_x_ex()\fR, \fBSRP_Calc_x()\fR and \fBSRP_Calc_A()\fR. See
\&\s-1RFC2945\s0 for a detailed description of their usage and the meaning of the various
\&\s-1BIGNUM\s0 parameters to these functions.
.PP
Most of these functions come in two forms. Those that take a \fIlibctx\fR and
\&\fIpropq\fR parameter, and those that don't. Any cryptogrpahic functions that
are fetched and used during the calculation use the provided \fIlibctx\fR and
\&\fIpropq\fR. See \*(L"\s-1ALGORITHM FETCHING\*(R"\s0 in \fBcrypto\fR\|(7) for more details. The variants
that do not take a \fIlibctx\fR and \fIpropq\fR parameter use the default library
context and property query string. The \fBSRP_Calc_server_key()\fR and \fBSRP_Calc_A()\fR
functions do not have a form that takes \fIlibctx\fR or \fIpropq\fR parameters because
they do not need to fetch any cryptographic algorithms.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
