- pyca/cryptography version 48 now supports post-quantum algorithms ML-KEM and ML-DSA, funded by the Sovereign Tech Agency.
- Post-quantum cryptography addresses threats from quantum computers, with U.S. government migration deadlines set for 2030-2031.
- ML-DSA signatures and ML-KEM key exchange have larger data sizes than classical algorithms (e.g., Ed25519, X25519).
- SLH-DSA, a hash-based signature standard, is not yet supported but is under development for future updates.
- Protocol integration and application adoption are needed for a complete migration to post-quantum cryptography in Python.
