Lepton's Crack is a generic password cracker. It is easily-customizable with a simple plugin system and allows system administrators to review the quality of the passwords being used on their systems. It can perform a dictionary-based (wordlist) attack as well as a brute force (incremental) password scan, including the use of regular expressions. It supports standard MD4 hash, standard MD5 hash, NT MD4/Unicode, Lotus Domino HTTP password (R4), and SHA-1 hash formats. LM (LAN Manager) plus appending and prepending of characters is available in the Development branch (strongly recommended).

Release Notes: REGEX enumeration when len is greater than 1 now starts with len=1 and proceeds up to max_len. Charset and REGEXes can now be saved to a text file. -stdin allows feeding lcrack from an external password generator. The mktbl program is now included to generate pre-computed hash tables (rainbow tables). LM hsa been briefly deactivated until the next version to rework it.
Release Notes: This version adds a SHA-1 module.
Release Notes: Several bugfixes and optimizations were made, including a minor optimization (~2%) of the Lotus Domino hash calculation. If a password was repeated in the input file, only one of them was found. This has been fixed.
