P5-string-compare-constanttime

Perl extension for timing side-channel protected string compare

This module provides one function, equals not exported by default.

You should pass this function two strings of the same length. It will return true if they are string-wise identical and false otherwise, just like eq. However, comparing any two differing strings will take a fixed amount of time, unlike eq.
