Package catalog

26 packages across five areas of the post-quantum transition. Each one installs on its own, ships its own tests and evidence, and states what it does not do.

  • PQ cryptography · 4 packages

    ML-KEM, ML-DSA and SLH-DSA through maintained implementations, hybrid key establishment and signatures, and safe defaults for files and tokens.

  • Migration & readiness · 7 packages

    Find cryptography in code and on the wire, emit CBOMs, score readiness, gate CI with policy-as-code and assemble compliance evidence.

  • Interoperability · 4 packages

    Wire formats, JOSE, X.509/CSR and TLS hybrid groups that carry larger post-quantum keys, ciphertexts and signatures through real protocols.

  • Conformance · 2 packages

    Official NIST ACVP vectors and strict FIPS 203/204 boundary checks that prove an implementation and a migration are correct.

  • Quantum-inspired · 9 packages

    Classical solvers modelled on quantum dynamics for Ising and QUBO problems. Kept separate from security: no cryptographic claims.
