Functions

func DeriveConcatKDF

func DeriveConcatKDF(keydatalen int, sharedSecret, algId, partyUInfo, partyVInfo, suppPubInfo, suppPrivInfo []byte, h hash.Hash) []byte

DeriveConcatKDF implements NIST SP 800-56A Concatenation Key Derivation Function. Derives key material of keydatalen bits size given Z (sharedSecret), OtherInfo (AlgorithmID | PartyUInfo | PartyVInfo | SuppPubInfo | SuppPrivInfo) and hash function

func DerivePBKDF2

func DerivePBKDF2(password, salt []byte, iterationCount, keyBitLength int, h func() hash.Hash) []byte

DerivePBKDF2 implements Password Based Key Derivation Function 2, RFC 2898. Derives key of keyBitLength size, given password, salt, iteration count and hash function
