srd-crack #49
Description
Password recovery tool. For the purposes of this issue, specify the character set to search (1aAsb) (numbers, lower case letters, upper case letters, everything else ascii, and full binary). Also specify the maximum password lengths to search (-l).
The purpose is as much for demonstrating password (non-)security as for really cracking passwords. A good password cracker would consider password frequencies and patterns from a known corpus of real-world passwords.
