gnutls_srtp_get_keys(3) gnutls gnutls_srtp_get_keys(3) NAME 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 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.
