Open-source post-quantum readiness tooling by quantakrypto

Harvest Now, Decrypt Later — the vulnerable populations The Christman AI Project serves cannot wait."

From Q-Day to Exposure Curves: a capability-conditioned framework for post-quantum migration. Paper, LaTeX source, and the script that produces every number in it.

Measure the public key a host is actually serving, corroborate it against Certificate Transparency, and compute a post-quantum harvest deadline you can triage and export.

AegisPQC is a federated, zero-trust, post-quantum-safe messaging platform engineered to defend against global passive network observers, post-quantum decryption threats ("Harvest Now, Decrypt Later"), device seizure, and legal compulsion of infrastructure operators. It provides high-throughput payload streaming, strict metadata elimination at the p

Post-quantum cryptographic posture management with an in-path AI gateway. Discover, score, and remediate quantum-vulnerable crypto across code, certificates, endpoints, and AI agents.

Import a real dependency manifest, see which cryptography a quantum computer breaks first, and commit the date you must migrate by.

Post-quantum-protected encrypted SQLite vault built on SQLCipher — wraps the database encryption key with a hybrid PQC KEM so data stays confidential against "harvest-now, decrypt-later" adversaries. Crash-safe key rotation, fail-closed design, for .NET.

Post-quantum migration readiness instrument: survey your cryptographic inventory for harvest-now-decrypt-later exposure and export a verifiable report.

Qvidence (Quantum + Evidence) — bio/clinical evidence platform with PQC, consent routing, multi-jurisdiction regulator adapters, IP escrow, and incident replay. Built via PG/PGF.

Browser-based Harvest-Now-Decrypt-Later risk simulator built around the Mosca Inequality (X+Y>Z). 20+ algorithms, 4 CRQC scenarios, 5 org profiles, and cost-of-delay projections using 2025 GRI expert estimates.

Browser-based harvest-now-decrypt-later (HNDL) threat demo — intercept simulation, post-quantum migration urgency, timeline visualization. Part of crypto-lab.

See whether a site's post-quantum TLS protection is real or hollow. Runs the real handshakes, builds a CBOM, and exports a signed PDF.

Cryptography Bill of Materials scanner — inventory a codebase's crypto, classify post-quantum risk, map to NIST PQC, emit CycloneDX 1.6. Zero deps, nothing uploaded.
