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.
