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

Tool

What it does

Get it

qScan (@quantakrypto/qscan)

CLI that finds quantum-vulnerable crypto (RSA, (EC)DH, ECDSA, EdDSA, …) across 14 languages (JS/TS, Python, Go, Java/Kotlin/Scala, C#, Rust, Ruby, PHP, Elixir, C/C++, Swift, Objective-C, Dart, Solidity/Move/Cairo) and prints a readiness score. SARIF / JSON / CBOM / evidence (ISO 27001 A.8.24) / OpenVEX output, baselines, incremental & parallel scans. Compliance mandate gate: --mandate cnsa-2.0 / nist-ir-8547 reports each prohibited finding with its dated clause and fails the build on the mandate's deadlines (--lead-months, --fail-now). Opt-in --triage (BYOK LLM re-rank/explain) and a qremediate codemod CLI.

npx @quantakrypto/qscan ./

MCP (@quantakrypto/mcp)

Model Context Protocol server that gives AI coding agents post-quantum readiness tools (16 tools — scan, inventory, explain, suggest-hybrid, CBOM, plan-migration, triage, remediate, probe-endpoint, …). Local stdio + hostable HTTP.

claude mcp add quantakrypto npx @quantakrypto/mcp

Sieve (@quantakrypto/sieve)

Conformance battery for ML-KEM (FIPS 203), ML-DSA (FIPS 204), and SLH-DSA (FIPS 205) implementations, driven over a JSON stdin/stdout protocol.

npx @quantakrypto/sieve --help

Action (@quantakrypto/action)

GitHub Action that runs the qScan/Sieve/qProbe checks in CI, writes SARIF for code-scanning upload, annotates the diff, and fails the build only on new quantum-vulnerable crypto.

uses: quantakrypto/pqc-tools/packages/action@v1

agent (@quantakrypto/agent)

Optional, zero-dependency BYOK (bring-your-own-key) LLM client (native fetch; Anthropic + OpenAI-compatible adapters) that powers qScan --triage and qremediate --llm. Networked, key-holding — kept isolated (see also qProbe).

npm i @quantakrypto/agent

qProbe (@quantakrypto/qprobe)

Actively probes live TLS/SSH endpoints you own for post-quantum readiness — PQC-hybrid key exchange (X25519MLKEM768) and classical certificate posture. Gated behind an ownership attestation; reports, never modifies ("engine disposes"). See THREAT-MODEL.

npx @quantakrypto/qprobe --i-own-this host

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

# 4. Gate against a compliance mandate's dated deadlines (CNSA 2.0 / NIST IR 8547).
#    Verdicts also ride in --format json/sarif/evidence; --policy lets an org
#    acknowledge families it is knowingly migrating (exempt from early gating).
npx @quantakrypto/qscan ./ --mandate cnsa-2.0 [--policy .quantakrypto/crypto-policy.json]

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 conformance-tests the replacement (sieve runs any ML-KEM/ML-DSA/SLH-DSA implementation against FIPS 203/204/205, with exact-value KATs when you supply official NIST ACVP vectors). 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).

Exposes a scan tool over MCP.
