SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_srtp_get_keys(gnutls_session_t session, void * key_material,
12       unsigned int key_material_size, gnutls_datum_t * client_key, gnutls_da‐
13       tum_t  *  client_salt,  gnutls_datum_t  *  server_key, gnutls_datum_t *
14       server_salt);
15

ARGUMENTS

17       gnutls_session_t session
18                   is a gnutls_session_t type.
19
20       void * key_material
21                   Space to hold the generated key material
22
23       unsigned int key_material_size
24                   The maximum size of the key material
25
26       gnutls_datum_t * client_key
27                   The master client write key, pointing inside the key  mate‐
28                   rial
29
30       gnutls_datum_t * client_salt
31                   The master client write salt, pointing inside the key mate‐
32                   rial
33
34       gnutls_datum_t * server_key
35                   The master server write key, pointing inside the key  mate‐
36                   rial
37
38       gnutls_datum_t * server_salt
39                   The master server write salt, pointing inside the key mate‐
40                   rial
41

DESCRIPTION

43       This is a helper function to generate the keying material for SRTP.  It
44       requires  the  space of the key material to be pre-allocated (should be
45       at least 2x the maximum key size and  salt  size).  The   client_key  ,
46       client_salt  ,  server_key and  server_salt are convenience datums that
47       point inside the key material. They may be NULL.
48

RETURNS

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

54       Since 3.1.4
