Functions ¶
func ConstantTimeByteEq ¶
ConstantTimeByteEq returns 1 if x == y and 0 otherwise.
func ConstantTimeCompare ¶
ConstantTimeCompare returns 1 if the two slices, x and y, have equal contents and 0 otherwise. The time taken is a function of the length of the slices and is independent of the contents. If the lengths of x and y do not match it returns 0 immediately.
func ConstantTimeCopy ¶
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 ¶
ConstantTimeEq returns 1 if x == y and 0 otherwise.
func ConstantTimeLessOrEq ¶ added in go1.2
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 ¶
ConstantTimeSelect returns x if v == 1 and y if v == 0. Its behavior is undefined if v takes any other value.
