RAR Key recovers passwords for RAR archives. Features All versions of RAR are supported including 3.x   Brute-Force, Xieve™ or Dictionary attacks are used to recover the password Additional user dictionaries support, case changes, multiple mistypes and other modifications for each dictionary word Program automatically saves password search state and can resume after a stop or a crash Patterns can be used to minimize search time if any part of the password is known Non-English characters in passwords are supported Full install/uninstall support Xieve™ Passware developed Xieve™ optimization, which dramatically boosts Brute-Force attack speed by skipping password checks of nonsense combinations of characters. With 95% recovery rate for English words, password search speed is over 75,000,000 passwords per minute. Limitations RAR uses relatively strong encryption algorithm that makes instant password calculation impossible. Brute-force attack is the slowest approach and can test all the passwords of up to 8 characters. Xieve™ attack is much faster and is capable of recovering passwords of up to 10 characters. Dictionary attack is the fastest method - there is no limitation on password length. Password recovery speed for archives created using RAR 3.x is very slow - about 5-10 passwords per second on average PC.
