SYNOPSIS
#include <openssl/srp.h>
The following functions have been deprecated since OpenSSL 3.0, and can
be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
version value, see openssl_user_macros(7):
/* server side .... */
BIGNUM *SRP_Calc_server_key(const BIGNUM *A, const BIGNUM *v, const BIGNUM *u,
const BIGNUM *b, const BIGNUM *N);
BIGNUM *SRP_Calc_B_ex(const BIGNUM *b, const BIGNUM *N, const BIGNUM *g,
const BIGNUM *v, OSSL_LIB_CTX *libctx, const char *propq);
BIGNUM *SRP_Calc_B(const BIGNUM *b, const BIGNUM *N, const BIGNUM *g,
const BIGNUM *v);
BIGNUM *SRP_Calc_u_ex(const BIGNUM *A, const BIGNUM *B, const BIGNUM *N,
OSSL_LIB_CTX *libctx, const char *propq);
BIGNUM *SRP_Calc_u(const BIGNUM *A, const BIGNUM *B, const BIGNUM *N);
/* client side .... */
BIGNUM *SRP_Calc_client_key_ex(const BIGNUM *N, const BIGNUM *B, const BIGNUM *g,
const BIGNUM *x, const BIGNUM *a, const BIGNUM *u,
OSSL_LIB_CTX *libctx, const char *propq);
BIGNUM *SRP_Calc_client_key(const BIGNUM *N, const BIGNUM *B, const BIGNUM *g,
const BIGNUM *x, const BIGNUM *a, const BIGNUM *u);
BIGNUM *SRP_Calc_x_ex(const BIGNUM *s, const char *user, const char *pass,
OSSL_LIB_CTX *libctx, const char *propq);
BIGNUM *SRP_Calc_x(const BIGNUM *s, const char *user, const char *pass);
BIGNUM *SRP_Calc_A(const BIGNUM *a, const BIGNUM *N, const BIGNUM *g);
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 B and u parameters are used on the server side and are calculated
via SRP_Calc_B(3),
SRP_Calc_u_ex() and SRP_Calc_u(). The client key and x and 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 libctx and
propq parameter, and those that don't. Any cryptogrpahic functions that
are fetched and used during the calculation use the provided libctx and
propq. See "ALGORITHM FETCHING" in crypto(7) for more details. The
variants that do not take a libctx and 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 libctx or
propq parameters because they do not need to fetch any cryptographic
algorithms.
RETURN VALUES
All these functions return the calculated key or parameter, or NULL on
error.

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.
