The te-edu Password Meter class can be used to check whether a password is strong enough to not be guessed easily. It can perform several tests on a given password string to compute a score that represents the strength of a password. Password checking is based on brute force attack class A and considers 10 million password checks in one minute. It checks characters, character pairs, repeated characters, time needed to be discovered, character standard entropy, etc.
ua is a simple command line tool that finds sets of identical files. The name is derived from the Hungarian word ugyanaz, meaning the same. The development of ua was motivated by the disturbingly often recurring event of waiting too long for a shell script using sorts, md5sums, diffs, and the like to finish finding identical files.
