Python Now Has a Post-Quantum Encryption Library

Post-quantum cryptographic primitives ML-KEM and ML-DSA are now available in pyca/cryptography, making them pip-installable across the Python ecosystem.
For engineers building systems that handle long-lived secrets, this puts NIST-standardized post-quantum algorithms within reach of any Python project without custom builds or external dependencies. The practical takeaway is crypto agility: adopting these primitives now, while there is no emergency, reduces migration pressure later.

ML-KEM (key establishment) and ML-DSA (digital signatures), both NIST-standardized, are now supported in pyca/cryptography.
Funding from the Sovereign Tech Agency made the implementation possible.
The work is framed as a proactive move toward crypto agility rather than a response to an active threat.
