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 ses‐
sion 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 ran‐
dom fields directly, and is recommended if you want to generate pseudo
random data unique for each session.
