Name

gnutls_srp_verifier — Used to calculate an SRP verifier

Synopsis

#include <gnutls/gnutls.h>
int gnutls_srp_verifier( const char *   username,
  const char *   password,
  const gnutls_datum_t *   salt,
  const gnutls_datum_t *   generator,
  const gnutls_datum_t *   prime,
  gnutls_datum_t *   res);

ARGUMENTS

const char * username

is the user's name

const char * password

is the user's password

const gnutls_datum_t * salt

should be some randomly generated bytes

const gnutls_datum_t * generator

is the generator of the group

const gnutls_datum_t * prime

is the group's prime

gnutls_datum_t * res

where the verifier will be stored.

DESCRIPTION

This function will create an SRP verifier, as specified in RFC2945. The prime and generator should be one of the static parameters defined in gnutls/extra.h or may be generated using the libgcrypt functions gcry_prime_generate() and gcry_prime_group_generator().

The verifier will be allocated with malloc and will be stored in res using binary format.

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, or an error code.

REPORTING BUGS
