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.

Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
