NAME
       gnutls_pbkdf2 - API function

SYNOPSIS
       #include <gnutls/crypto.h>

       int gnutls_pbkdf2(gnutls_mac_algorithm_t mac, const gnutls_datum_t *
       key, const gnutls_datum_t * salt, unsigned iter_count, void * output,
       size_t length);

ARGUMENTS
       gnutls_mac_algorithm_t mac
                   the mac algorithm used internally

       const gnutls_datum_t * key
                   the initial keying material

       const gnutls_datum_t * salt
                   the salt

       unsigned iter_count
                   the iteration count

       void * output
                   the output value

       size_t length
                   the desired length of the output key

DESCRIPTION
       This function will derive a variable length keying material from a
       password according to PKCS 5 PBKDF2.

RETURNS
       Zero or a negative error code on error.

SINCE
       3.6.13
