gnutls_prf_raw

gnutls_prf_raw(3)						      gnutls							 gnutls_prf_raw(3)

NAME

       gnutls_prf_raw - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       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);

ARGUMENTS

       gnutls_session_t session
		   is a gnutls_session_t structure.

       size_t label_size
		   length of the  label variable.

       const char * label
		   label used in PRF computation, typically a short string.

       size_t seed_size
		   length of the  seed variable.

       const char * seed
		   optional extra data to seed the PRF with.

       size_t outsize
		   size of pre-allocated output buffer to hold the output.

       char * out  pre-allocated buffer to hold the generated data.

DESCRIPTION

       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 particular
       purpose.

       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 each session.

RETURNS

       GNUTLS_E_SUCCESS on success, or an error code.
