Advanced Archive Password Recovery by ElcomSoft
Win32, shareware, 30 day free trial, $49 Standard / $99 Professional Edition (purchase)

A program for recovering lost or forgotten passwords for ZIP (PKZIP/WinZip), RAR/WinRAR (both versions 2.0 to 2.8 and 2.9/3.x), ACE/WinACE, and ARJ/WinArj archives. Supports the customizable "brute-force" attack, effectively optimized for speed (for ZIP, it tests about 15 million passwords per second on a 1 GHz Pentium III); dictionary-based attack, and very fast and effective known-plaintext attack. For WinZip archives with 5 or more encrypted files, guaranteed decryption is available. Multilanguage interface is provided.

RAR Password Cracker by dnSoft Research Group
Win32, shareware, free trial, $30 (purchase)

A similar cracker from dnSoft Research Group that was first to introduce support for RAR/WinRAR versions 2.9/3.x (in addition to 2.0 to 2.8). It recovers by the method of exhaustive search of all possible combinations of characters ("brute-force"), or using passwords from a list ("wordlist" or "dictionary" method). Self-extracting archives (SFX) and multi-volume archives are supported. The program is able to save current state of cracking (you can interrupt the program at any time, and restart from the same state later).
