package subtle

import "crypto/internal/subtle"

Package subtle implements functions that are often useful in cryptographic code but require careful thought to use correctly.

This is a mirror of golang.org/x/crypto/internal/subtle.

func AnyOverlap ¶ Uses

func AnyOverlap(x, y []byte) bool

AnyOverlap reports whether x and y share memory at any (not necessarily corresponding) index. The memory beyond the slice length is ignored.

func InexactOverlap ¶ Uses

func InexactOverlap(x, y []byte) bool

InexactOverlap reports whether x and y share memory at any non-corresponding index. The memory beyond the slice length is ignored. Note that x and y can have different lengths and still not have any inexact overlap.

InexactOverlap can be used to implement the requirements of the crypto/cipher AEAD, Block, BlockMode and Stream interfaces.
