Description
A ZIP archive may contain many entries whose content can be compressed and/or encrypted. In particular, entries can be encrypted with a password-based symmetric encryption algorithm referred to as traditional PKWARE encryption, legacy encryption or ZipCrypto.
bkcrack is a command-line tool which implements a known plaintext attack by Biham and Kocker. The main features are:
Recover internal state from ciphertext and plaintext.
Change a ZIP archive's password using the internal state.
Recover the original password from the internal state.
