gnutls_prf_raw - API function
int gnutls_prf_raw(gnutls_session_t session, size_t label_size, const char * label, size_t
seed_size, const char * seed, size_t outsize, char * out);
is a gnutls_session_t structure.
length of the label variable.
const char * label
label used in PRF computation, typically a short string.
length of the seed variable.
const char * seed
optional extra data to seed the PRF with.
size of pre-allocated output buffer to hold the output.
char * out pre-allocated buffer to hold the generated data.
Apply the TLS Pseudo-Random-Function (PRF) on the master secret and the provided data.
The label variable usually contains a string denoting the purpose for the generated data.
The seed usually contains data such as the client and server random, perhaps together
with some additional data that is added to guarantee uniqueness of the output for a par-
Because the output is not guaranteed to be unique for a particular session unless seed
includes the client random and server random fields (the PRF would output the same data on
another connection resumed from the first one), it is not recommended to use this function
directly. The gnutls_prf() function seeds the PRF with the client and server random
fields directly, and is recommended if you want to generate pseudo random data unique for
GNUTLS_E_SUCCESS on success, or an error code.
