ConstantTimeByteEq returns 1 if x == y and 0 otherwise.

func ConstantTimeByteEq(x, y uint8) int

ConstantTimeCompare returns 1 if and only if the two slices, x and y, have equal contents. The time taken is a function of the length of the slices and is independent of the contents.

func ConstantTimeCompare(x, y []byte) int

ConstantTimeCopy copies the contents of y into x (a slice of equal length) if v == 1. If v == 0, x is left unchanged. Its behavior is undefined if v takes any other value.

func ConstantTimeCopy(v int, x, y []byte)

ConstantTimeEq returns 1 if x == y and 0 otherwise.

func ConstantTimeEq(x, y int32) int

ConstantTimeLessOrEq returns 1 if x <= y and 0 otherwise. Its behavior is undefined if x or y are negative or > 2**31 - 1.

func ConstantTimeLessOrEq(x, y int) int

ConstantTimeSelect returns x if v is 1 and y if v is 0. Its behavior is undefined if v takes any other value.

func ConstantTimeSelect(v, x, y int) int
