Krylack RAR Password Recovery regains access to your own RAR archives. It recovers forgotten passwords from RAR3 and RAR5, header- or data-encrypted, with dictionary, mask and brute-force methods and GPU acceleration. WinRAR has shipped two archive generations: RAR3, whose protection already uses a slow key-derivation step, and RAR5, which derives the key with PBKDF2-HMAC-SHA256 over many iterations and is one of the tougher archive formats to recover. It handles both, header- or data-encrypted, including archives whose file names are hidden. A compatible GPU multiplies the number of candidates tested per second, so it makes a real difference on RAR. Dictionary, Smart (mask and pattern) and brute-force methods are available so you can match the approach to what you remember. It runs entirely on your own PC, so your files never leave your computer. For RAR archives you own or are authorized to open. A one-time purchase includes a perpetual license and free updates within the edition.
