hmac_sha1_vector - HMAC-SHA1 over data vector (RFC 2104) : Key for HMAC operations : Length of the key in bytes : Number of elements in the data vector : Pointers to the data areas : Lengths of the data blocks : Buffer for the hash (20 bytes) Returns: 0 on success, -1 on failure

pbkdf2_sha1 - SHA1-based key derivation function (PBKDF2) for IEEE 802.11i : ASCII passphrase : SSID : SSID length in bytes : Number of iterations to run : Buffer for the generated key : Length of the buffer in bytes Returns: 0 on success, -1 of failure
This function is used to derive PSK for WPA-PSK. For this protocol, iterations is set to 4096 and buflen to 32. This function is described in IEEE Std 802.11-2004, Clause H.4. The main construction is from PKCS#5 v2.0.

sha1_prf - SHA1-based Pseudo-Random Function (PRF) (IEEE 802.11i, 8.5.1.1) : 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 Returns: 0 on success, -1 of failure
This function is used to derive new, cryptographically separate keys from a given key (e.g., PMK in IEEE 802.11i).
