Python Now Has a Post-Quantum Encryption Library
TechTarget, Tuesday, August 19th, 2025
ML-KEM and ML-DSA are now pip-installable through Python's cryptography library.
The post-quantum cryptographic standards ML-KEM and ML-DSA are now available in Python's cryptography library and installable via pip.
That removes the main practical friction for developers wanting to experiment with or adopt post-quantum primitives. Schneier's framing is that implementation should happen proactively rather than when the need becomes urgent.
He also emphasizes crypto agility, meaning building systems that can swap algorithms, as the more durable goal than any specific algorithm choice.
