.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 \fBSRP_user_pwd_new()\fR function allocates a structure to store a user verifier
record.
.PP
The \fBSRP_user_pwd_free()\fR function frees up the \fBuser_pwd\fR structure.
If \fBuser_pwd\fR is \s-1NULL,\s0 nothing is done.
.PP
The \fBSRP_user_pwd_set1_ids()\fR function sets the username to \fBid\fR and the optional
user info to \fBinfo\fR for \fBuser_pwd\fR.
The library allocates new copies of \fBid\fR and \fBinfo\fR, the caller still
owns the original memory.
.PP
The \fBSRP_user_pwd_set0_sv()\fR function sets the user salt to \fBs\fR and the verifier
to \fBv\fR for \fBuser_pwd\fR.
The library takes ownership of the values, they should not be freed by the caller.
.PP
The \fBSRP_user_pwd_set_gN()\fR function sets the \s-1SRP\s0 group parameters for \fBuser_pwd\fR.
The memory is not freed by \fBSRP_user_pwd_free()\fR, the caller must make sure it is
freed once it is no longer used.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBSRP_user_pwd_set1_ids()\fR returns 1 on success and 0 on failure or if \fBid\fR was \s-1NULL.\s0
.PP
\&\fBSRP_user_pwd_set0_sv()\fR returns 1 if both \fBs\fR and \fBv\fR are not \s-1NULL, 0\s0 otherwise.
