Crypto support is not enabled by default to reduce class footprint in final executable. In project properties dialog try setting ZIP_CRYPTO = 1 in conditional compilation setting like this

Keep in mind that by default cZipArchive uses the weaker ZipCrypto encryption to be most compatible with Windows Explorer but this can easily be cracked. You can try setting EncrStrength parameter to 1, 2 or 3 for stronger AES based encryption which is compatible with WinZip, 7-zip and almost every other zip utility except Windows Explorer.
