func ConstantTimeStringEqual ¶

func ConstantTimeStringEqual(given, actual string) bool

ConstantTimeStringEqual performs a constant-time comparison of two strings to prevent timing attacks. It returns true if the strings are equal, false otherwise. The comparison time depends only on the length of the strings and not their contents.

This function is intended for comparing sensitive strings like passwords or authentication tokens. For regular string comparison, use the == operator.
