A Python script obfuscation tool for educational and research purposes. CalypsisOBF helps protect Python code by applying various obfuscation techniques to make reverse engineering more difficult.
This tool is intended for educational purposes only. The author is not responsible for any misuse of this software. Users are responsible for ensuring compliance with applicable laws and regulations.
The following images demonstrate the effectiveness of the obfuscation in reducing detection rates:
Without obfuscation: Higher detection rate from antivirus engines
With obfuscation: Significantly reduced detection rate, demonstrating the effectiveness of the tool
CalypsisOBF applies multiple protection layers to secure your Python code:
- AST Variable Renaming
- Code Noise Injection
- Bytecode Compilation (marshal)
- XOR Encryption
- Hexlify & Base64 Encoding
- zlib Compression
- LZMA Compression
- Custom Loader Stub
print("Hello, world!")# The output will not look like Python code anymore and will contain a loader stub like: import marshal, zlib, lzma, base64, binascii JgtjWkwqbQ = b'\xfd7zXZ\x00\x00\x04\xe6\xd6\xb4F\x02\x00!\x01\x16\x00\x00\x00t/\xe5\xa3\x01\x00\xf2x\x9cuP\xc1n\xc30\x08\xfd\xa5,K\x8f;,\x9am\xd5\x12D\xa9\x9cXp\xdd\x0e1\x89\xcfM\xfd\xf5\xc3Q\xabN\x9bv\xb0\xe0\x01\xef\xe1\x07\x88\x17\x88\xb0S\xb1\xff\xc7\xfc\xb7\x0e\xc5\xaf\xc3\x03\x87\xa9\xa1bN\xec`\xe7\x80\x8a\xd7\x9b\xd63:\xb8\xfe\xe6q\xb0\xf7~\x9f\xa0\xd5~`\x81v\xea\xa8\xf8D\x19\x17\n\xdb\x82\xce\xae\x14/\x0b\xc7i\'a\x8d\xe7R1\x86sGU\xff\xd03\x1d\xe7\xca\xd3<CCbU\xcft\x149a\xb0\x89Z\x9fP\x96D\xfaPs\x92\xf1\x04\xd1\xe8\xdcg7\x04R\x9e)?}A\xf4\xc2\x8eu\xef\xbc\xa8\xce+\xc9%A67\n}\xc2\xca\x0bsf\xddAe\xcb\xec\xac\xd49\x8c\xe7\xe6\xf8\x97\xe3L\x822<}>}\x8b_\xd5\xe7\xfdN5\xea\xbd\x8f\xbb\xbc\xef\x83\xabxl \xd6\xde\xac\xf3\xe3\x0b\x84M\xa8\xc5\r?z\xa1\xac\xbe\xcb\xd7\xc3\xef\xdb7"|\x95\x88\x00\x00-\xd5\xdd\xef8\x14\x9eh\x00\x01\x8b\x02\xf3\x01\x00\x00\xd8\xb0\xf3X\xb1\xc4g\xfb\x02\x00\x00\x00\x00\x04YZ' yFl_DHKGxI = 193 h5qF7xr6Kz = lzma.decompress(JgtjWkwqbQ) TZAs7F8Zgg = zlib.decompress(h5qF7xr6Kz) m80zR3YEzl = base64.b64decode(TZAs7F8Zgg) qwpN5gdbKp = binascii.unhexlify(m80zR3YEzl) ZLIHD20fXM = bytes(b ^ yFl_DHKGxI for b in qwpN5gdbKp) ft37atyAKP = marshal.loads(ZLIHD20fXM) exec(ft37atyAKP)Note: The obfuscated Python file is meant to run as a script but is not intended to be human-readable. It works on standard Python interpreters.
- Advanced Python code obfuscation
- Multiple obfuscation layers
- Easy to use interface
