Documentation

Overview

Package cast5 implements CAST5, as defined in RFC 2144.

CAST5 is a legacy cipher and its short block size makes it vulnerable to birthday bound attacks (see https://sweet32.info). It should only be used where compatibility with legacy systems, not security, is the goal.

Deprecated: any new system should use AES (from crypto/aes, if necessary in an AEAD mode like crypto/cipher.NewGCM) or XChaCha20-Poly1305 (from golang.org/x/crypto/chacha20poly1305).
