quantakrypto-tools

Open-source post-quantum readiness tooling by quantakrypto.
Find quantum-vulnerable cryptography in any codebase, wire post-quantum readiness
into your editor and your CI, and conformance-test post-quantum implementations —
with zero runtime dependencies (Node built-ins only).

Design goals: simple, clean, reusable code; zero runtime dependencies;
everything documented, tested, and example-driven.

What's inside

All of qScan, MCP, the Action, agent, and qProbe share the engine in
@quantakrypto/core (npm i @quantakrypto/core) — detectors,
the vulnerable-dependency DB, the readiness score, SARIF/JSON/CBOM/evidence/OpenVEX
reporting, and the
offline agent-plane primitives (context redactor, verify_fix gate, codemods, patch
policy). Sieve is standalone: it tests other implementations and implements no
crypto itself.

Infrastructure coverage. Beyond application source, the shared core engine
carries config-scope detectors for Terraform/OpenTofu IaC and cloud KMS, JSON
Web Keys, Kubernetes / cert-manager / Istio, CI/CD artifact & code signing
(cosign/GPG/jarsigner/codesign/minisign), secrets at rest (SOPS/age, PGP, Sealed
Secrets), message brokers (Kafka/MQTT), databases (pgcrypto, libpq sslmode), and
JOSE/JWE key management — so qscan, the Action, and MCP flag infrastructure
crypto with no extra install. qProbe adds the live-endpoint dimension (see the
table above). The narrative anchor for infrastructure is harvest now, decrypt
later: data and secrets captured today are decryptable once a CRQC exists.

Quick start

# 1. Scan a codebase for quantum-vulnerable cryptography.
npx @quantakrypto/qscan ./

# 2. Give your AI coding agent post-quantum readiness tools.
claude mcp add quantakrypto npx @quantakrypto/mcp

# 3. Conformance-test a post-quantum implementation (adapter speaks the JSON protocol).
npx @quantakrypto/sieve --impl "node ./my-impl.js" --param ml-kem-768

Add the CI gate by dropping
packages/action/examples/quantum-readiness.yml
into .github/workflows/, or wire it up directly:

- uses: quantakrypto/pqc-tools/packages/action@v1
  with:
    path: "."
    severity-threshold: "high"

Each package README has the full options reference and more examples:
qScan ·
MCP ·
Sieve ·
Action ·
core ·
agent.

Using quantakrypto alongside a PQC library (liboqs / OQS)

quantakrypto does not implement post-quantum cryptography, by design — it is
the scanner, the CI gate, and the conformance harness you wrap around a real PQC
library like liboqs / Open Quantum Safe. They
compose: quantakrypto finds and gates classical crypto (qscan, the Action),
tells you what to migrate to and in what order (qscan --tier, MCP
plan_migration, qremediate), and proves the replacement is correct
(sieve conformance-tests any ML-KEM/ML-DSA/SLH-DSA implementation against
FIPS 203/204/205). liboqs supplies the primitives.

See the worked end-to-end walkthrough — scan → migrate → verify → gate — in
examples/liboqs-migration/.

Development

Requires Node ≥ 20.

npm install        # links the workspaces
npm run build      # tsc --build (project references)
npm test           # node:test across all packages

The toolchain is intentionally tiny: TypeScript + tsx (to run node:test on
.ts) are the only dev dependencies; there are no runtime dependencies.

Documentation & compliance

Full documentation lives in docs/:

• Objectives & scope — what the toolchain is for, what
  each library does, the load-bearing decisions, and the deliberate scope
  boundaries. Start here.
• Architecture decisions — the immutable "why" behind
  each load-bearing choice (zero deps, shared core contract, two-plane agent, …).
• Standards & compliance — what the tools touch and
  could align to: NIST FIPS 203/204/205, SP 800-208, CNSA 2.0, SARIF, CWE,
  ISO/IEC 27001 (A.8.24), Common Criteria, FIPS 140-3, EU DORA/NIS2, US
  M-23-02 / NSM-10, and OSS assurance (SLSA, OpenSSF Scorecard, SPDX/REUSE).
