sha256_prf - SHA256-based Pseudo-Random Function (IEEE 802.11r, 8.5.1.5.2) : Key for PRF : Length of the key in bytes : A unique label for each purpose of the PRF : Extra data to bind into the key : Length of the data : Buffer for the generated pseudo-random key : Number of bytes of key to generate
This function is used to derive new, cryptographically separate keys from a given key.
