Functions

func AnyOverlap

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 ConstantTimeAllZero added in v1.0.2048

func ConstantTimeAllZero(bytes []byte) bool

func InexactOverlap

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.

func SliceForAppend added in v1.0.2048

func SliceForAppend(in []byte, n int) (head, tail []byte)

SliceForAppend takes a slice and a requested number of bytes. It returns a slice with the contents of the given slice followed by that many bytes and a second slice that aliases into it and contains only the extra bytes. If the original slice has sufficient capacity then no allocation is performed.
