} // A Stream represents a stream cipher. type Stream interface { // XORKeyStream XORs each byte in the given slice with a byte from the // cipher's key stream. Dst and src must overlap entirely or not at all. // // If len(dst) < len(src), XORKeyStream should panic. It is acceptable // to pass a dst bigger than src, and in that case, XORKeyStream will // only update dst[:len(src)] and will not touch the rest of dst. //
