Get RAR Password Unlocker Free. This tool helps you in recovering all your lost and forgotten passwords in order to access your rar files and provides you the great facility to never lose your passwords again.
RAR/WinRAR archiver version 2.x used its proprietary, but rather strong encryption algorithm. At least no RAR 2.0 attacks were known except brute force for password recovery.
Starting from version 3.0, RAR has been using a strong AES algorithm, which also doesn’t allow any attacks more effective than the brute force. Besides, the key derivation function uses more than 70000 SHA-1 transformations and brute force rate on modern CPU is very low, only several hundreds of passwords per second.
RAR 5.0 encryption is quite the same, using PBKDF2 key derivation with SHA-256 hash and the rate is even slower (in 25-100% on different hardware comparing to RAR 3.0). This carries inference that RAR password encryption is one of the strongest between popular encryption systems in the context of brute force rate.
