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);
DESCRIPTIONAll 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_server_key(), SRP_Calc_B_ex(), SRP_Calc_B(), 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 VALUESAll these functions return the calculated key or parameter, or NULL on error.

HISTORYSRP_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.
