Encrypt Data Between Python and TypeScript (AES-GCM and RSA-OAEP)

Hacker News

Hi HN! I’m excited to share *Cross-Crypto*, a pair of libraries (Python [1] + TypeScript [2]) to encrypt data between frontend and backend with just 2 functions. *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 Most solutions are language-specific or use outdated encryption.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]).
