Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

encrypt

✓ import xxtea; xxtea.encrypt(data, key, padding=True)

✗ from xxtea import xxtea_encrypt

The legacy API used different function names. Use the module-level functions.

decrypt

✓ import xxtea; xxtea.decrypt(ciphertext, key, padding=True)

✗ from xxtea import decrypt

Direct import of decrypt works, but ensure you pass key as bytes, not string.

Encrypt and decrypt a bytes message using a key.

import os import xxtea data = b'Hello, World!' key = os.environ.get('XXTEA_KEY', 'secret').encode() encrypted = xxtea.encrypt(data, key) print(encrypted.hex()) decrypted = xxtea.decrypt(encrypted, key) print(decrypted)

Debug

Known issues

breakingThe encrypt() function returns bytes, not hex string as in some older versions or wrappers.

fix

Use xxtea.encrypt_hex() if you need hex output, or call .hex() on the result.

affects: >=3.0.0

gotchaThe key must be a bytes object; passing a string raises TypeError.

fix

Always encode your key: b'key' or 'key'.encode()

affects: all

gotchaPadding is enabled by default. Disable with padding=False only if you manually handle block size alignment.

fix

Leave padding=True unless you have a specific reason.

affects: >=1.2.0

deprecatedPython 2.7, 3.4, 3.5 support dropped in v3.0.0.

fix

Upgrade to Python >=3.6, preferably >=3.9.

affects: <3.0.0
