Direct answer
ZipCrypto prioritizes historical compatibility and has known structural weaknesses. AES-256 is a standardized block cipher with a 256-bit key, but archive security still depends on the surrounding format and password-to-key process.
Compare the protection layers
CipherZipCrypto uses a legacy stream design; AES-256 uses the AES standard with a 256-bit key.
Password handlingModern formats can use deliberately expensive key derivation; weak legacy schemes make guessing cheaper.
IntegrityA format should detect tampering or a wrong password without relying only on old checksums.
MetadataFile names may remain visible unless the chosen format supports and enables header encryption.
Do not test passwords against files you do not own
