Overview

Package subtle is similar to the 'cipher/subtle', only needed for very specific crypto operations.

Functions

func XorBytes

func XorBytes(dst, a, b []byte) int

XorBytes is the runtime import from "crypto/cipher.xorBytes" that can use hardware instructions for a 200% faster XOR operation.

func XorOp

func XorOp(value, key []byte)

XorOp will call the 'XorBytes' function but write the value back to the value instead.

If you need finer control, use the 'XorBytes' function.
