sha1_t_prf - EAP-FAST Pseudo-Random Function (T-PRF) : 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 of failure
This function is used to derive new, cryptographically separate keys from a given key for EAP-FAST. T-PRF is defined in RFC 4851, Section 5.5.
