tls_prf - Pseudo-Random Function for TLS (TLS-PRF, RFC 2246) : Key for PRF : Length of the key in bytes : A unique label for each purpose of the PRF : Seed value to bind into the key : Length of the seed : Buffer for the generated pseudo-random key : Number of bytes of key to generate Returns: 0 on success, -1 on failure.
This function is used to derive new, cryptographically separate keys from a given key in TLS. This PRF is defined in RFC 2246, Chapter 5.
