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 provided strictly for educational and research purposes. The author disclaims responsibility for misuse or for violating jurisdictional laws and regulations. Users must ensure all activities are legal under local rules.

The following scans were performed to illustrate the obfuscator's effectiveness.

• Higher detection rate from antivirus engines.
• 

• Significantly fewer detections, demonstrating improved code security.
• 

Note: Compiling your script to an executable (.exe) can further reduce detections, but some antivirus may still flag it depending on their heuristics.

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\xd3xf1\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
• Preserves code functionality
