Synopsis

#include <gnutls/gnutls.h>

int gnutls_srtp_get_keys(gnutls_session_t session, void * key_material, unsigned int key_material_size, gnutls_datum_t * client_key, gnutls_datum_t * client_salt, gnutls_datum_t * server_key, gnutls_datum_t * server_salt);

Arguments

gnutls_session_t session

is a gnutls_session_t type.

void * key_material

Space to hold the generated key material

unsigned int key_material_size

The maximum size of the key material

gnutls_datum_t * client_key

The master client write key, pointing inside the key material

gnutls_datum_t * client_salt

The master client write salt, pointing inside the key material

gnutls_datum_t * server_key

The master server write key, pointing inside the key material

gnutls_datum_t * server_salt

The master server write salt, pointing inside the key material

Description

This is a helper function to generate the keying material for SRTP. It requires the space of the key material to be pre-allocated (should be at least 2x the maximum key size and salt size). The  client_key ,  client_salt ,  server_key and  server_salt are convenience datums that point inside the key material. They may be NULL.

Returns

On success the size of the key material is returned, otherwise, GNUTLS_E_SHORT_MEMORY_BUFFER if the buffer given is not  sufficient, or a negative error code.

Since 3.1.4
