NAME¶

gsasl_scram_secrets_from_password - API function

SYNOPSIS¶

#include <gsasl.h>

int gsasl_scram_secrets_from_password(Gsasl_hash hash, const char * password, unsigned int iteration_count, const char * salt, size_t saltlen, char * salted_password, char * client_key, char * server_key, char * stored_key);

ARGUMENTS¶

Gsasl_hash hash

a Gsasl_hash element, e.g., GSASL_HASH_SHA256.

const char * password

input parameter with password.

unsigned int iteration_count

number of PBKDF2 rounds to apply.

const char * salt

input character array of saltlen length with salt for PBKDF2.

size_t saltlen

length of salt .

char * salted_password

pre-allocated output array with derived salted password.

char * client_key

pre-allocated output array with derived client key.

char * server_key

pre-allocated output array with derived server key.

char * stored_key

pre-allocated output array with derived stored key.

DESCRIPTION¶

Helper function to generate SCRAM secrets from a password. The
salted_password , client_key , server_key , and stored_key buffers must have room to hold digest for given hash , use GSASL_HASH_MAX_SIZE which is sufficient for all hashes.

Return value: Returns GSASL_OK if successful, or error code.
