0.300 into textproc/p5-String-Compare-ConstantTime.
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.
NOTE: If the lengths of the strings are different, equals will return
false right away. Also, comparing two identical strings will take a
different amount of time than comparing two differing strings.
