gnutls_srtp_get_keys – API function
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 structure.
- 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
