func ConstantTimeByteEq ¶
func ConstantTimeByteEq(x, y uint8) int
ConstantTimeByteEq returns 1 if x == y and 0 otherwise.
func ConstantTimeCompare ¶
func ConstantTimeCompare(x, y []byte) 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 ConstantTimeCopy ¶
func ConstantTimeCopy(v int, x, y []byte)
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 ConstantTimeEq ¶
func ConstantTimeEq(x, y int32) int
ConstantTimeEq returns 1 if x == y and 0 otherwise.
func ConstantTimeLessOrEq ¶
func ConstantTimeLessOrEq(x, y int) 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 ConstantTimeSelect ¶
func ConstantTimeSelect(v, 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.
