*Problem I faced:* Securing API payloads between React (TS) and Python is error-prone. Most solutions are language-specific or use outdated encryption.

*Solution:* - AES-256-GCM for data (authenticated encryption). - RSA-OAEP (4096-bit) for key exchange. - Works both ways: TS → Python or Python → TS.

*Why it’s unique:* - First lib focused on cross-language interoperability. - Handles key serialization/deserialization automatically. - 100% test coverage for compatibility.

Try it: - TS: `npm install cross-crypto-ts` [3] - Python: `pip install cross-crypto-py` [4]

Would love feedback! (Code & docs on GitHub [4]).
