SRP_user_pwd_new, SRP_user_pwd_free, SRP_user_pwd_set1_ids, SRP_user_pwd_set_gN, SRP_user_pwd_set0_sv - Functions to create a record of SRP user verifier information


#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):

SRP_user_pwd *SRP_user_pwd_new(void);
void SRP_user_pwd_free(SRP_user_pwd *user_pwd);

int SRP_user_pwd_set1_ids(SRP_user_pwd *user_pwd, const char *id, const char *info);
void SRP_user_pwd_set_gN(SRP_user_pwd *user_pwd, const BIGNUM *g, const BIGNUM *N);
int SRP_user_pwd_set0_sv(SRP_user_pwd *user_pwd, BIGNUM *s, BIGNUM *v);


All of the functions described on this page are deprecated. There are no available replacement functions at this time.

The SRP_user_pwd_new() function allocates a structure to store a user verifier record.

The SRP_user_pwd_free() function frees up the user_pwd structure. If user_pwd is NULL, nothing is done.

The SRP_user_pwd_set1_ids() function sets the username to id and the optional user info to info for user_pwd. The library allocates new copies of id and info, the caller still owns the original memory.

The SRP_user_pwd_set0_sv() function sets the user salt to s and the verifier to v for user_pwd. The library takes ownership of the values, they should not be freed by the caller.

The SRP_user_pwd_set_gN() function sets the SRP group parameters for user_pwd. The memory is not freed by SRP_user_pwd_free(), the caller must make sure it is freed once it is no longer used.


SRP_user_pwd_set1_ids() returns 1 on success and 0 on failure or if id was NULL.

SRP_user_pwd_set0_sv() returns 1 if both s and v are not NULL, 0 otherwise.

These functions were made public in OpenSSL 3.0 and are deprecated.
