Package-Level Functions (total 6, all are exported)

	 func ConstantTimeByteCompare(x, y []byte) (int, error)
		ConstantTimeByteCompare is a constant-time byte comparison of x and y. This function performs an absolute comparison
		if the two byte slices assuming they represent a big-endian number.

				 error if len(x) != len(y)
			  -1 if x <  y
			   0 if x == y
			  +1 if x >  y

	 func ECDSAKey(curve elliptic.Curve, d []byte) *ecdsa.PrivateKey
		ECDSAKey takes the given elliptic curve, and private key (d) byte slice
		and returns the private ECDSA key.

	 func ECDSAKeyFromPoint(curve elliptic.Curve, d *big.Int) *ecdsa.PrivateKey
		ECDSAKeyFromPoint takes the given elliptic curve and point and returns the
		private and public keypair

	 func ECDSAPublicKey(curve elliptic.Curve, x, y []byte) (*ecdsa.PublicKey, error)
		ECDSAPublicKey takes the provide curve and (x, y) coordinates and returns
		*ecdsa.PublicKey. Returns an error if the given points are not on the curve.

	 func HMACKeyDerivation(hash func() hash.Hash, bitLen int, key []byte, label, context []byte) ([]byte, error)
		HMACKeyDerivation provides an implementation of a NIST-800-108 of a KDF (Key Derivation Function) in Counter Mode.
		For the purposes of this implantation HMAC is used as the PRF (Pseudorandom function), where the value of
		`r` is defined as a 4 byte counter.

	 func VerifySignature(key *ecdsa.PublicKey, hash []byte, signature []byte) (bool, error)
		VerifySignature takes the provided public key, hash, and asn1 encoded signature and returns
		whether the given signature is valid.
