Quantum-Safe File Attestation Launches on AgentPMT: Post-Quantum Proof for Every File

Every audit trail you have ever built assumes the cryptographic math behind it will hold. That assumption has an expiration date, and quantum computing is writing it in ink.

Quantum-Safe File Attestation is now live on the AgentPMT marketplace. It is the first tool on the platform that signs file attestations using ML-DSA-65, a post-quantum digital signature algorithm executed through a hardware security module. Agents can discover and invoke it through AgentPMT’s dynamic MCP server, and every attestation is independently verifiable without calling back to the tool.

What It Does

The tool exposes three actions. attest_artifact takes a file already in storage, hashes it with SHA-256, and signs a structured attestation manifest using ML-DSA-65. The output is a complete attestation package containing the manifest, signature, signer public key, fingerprint, and an optional CAB verifier bundle. verify_attestation accepts any previously issued package and checks the signature, manifest integrity, artifact hash match, and bundle validity. get_public_key returns the signer’s public key and algorithm so third parties can verify signatures independently.

The attestation manifest itself is flexible. Beyond the mandatory file hash and timestamp, you can embed arbitrary metadata — version numbers, build identifiers, environment tags, provenance chains, or any key-value pairs relevant to your compliance workflow. Every invocation costs 5 credits, charged only on successful execution.

Why This Matters for Regulated Industries

Healthcare organizations operating under HIPAA need to prove that patient records, imaging files, and lab results have not been altered in transit or at rest. Financial institutions under SOX and Basel III face escalating audit requirements around data integrity. For teams already investing in AI compliance tools, quantum-resistant attestation closes the gap between automated document handling and tamper-evident proof. Government agencies handling classified or controlled unclassified information need cryptographic assurance that documents remain tamper-evident across systems and jurisdictions.

Traditional RSA and ECDSA signatures will not survive contact with fault-tolerant quantum computers. NIST finalized its post-quantum cryptography standards precisely because the migration timeline is measured in years, not decades. Organizations that wait until quantum machines are operational will be scrambling to re-sign millions of records retroactively. Those that adopt quantum-resistant attestation now build a chain of custody that remains valid regardless of what happens in quantum hardware.

Practical Applications

A compliance team can integrate this tool into their document management pipeline. When a regulatory filing is finalized, an agent attests it, stores the package alongside the original, and logs the attestation ID. Years later, during an audit, a different agent retrieves the package and runs verification against the stored hash. The signature math holds even if the rest of the cryptographic landscape has shifted.

In software supply chains, build artifacts — binaries, container images, configuration bundles — can be attested at the point of compilation. Downstream systems verify the package before deployment, establishing a tamper-evident chain from source to production. ML-DSA-65 ensures that chain remains intact against both classical and quantum adversaries. AI cybersecurity teams gain a verifiable chain of custody for forensic evidence that holds up under both classical and post-quantum scrutiny.

For regtech AI platforms automating regulatory reporting, attested evidence files carry cryptographic proof of integrity that courts and regulators can independently verify using just the public key. No API callbacks. No vendor lock-in. The math speaks for itself.

The Migration Window Is Open

Post-quantum cryptography demands attention today. NIST published the standards. The hardware security modules support the algorithms. Regulated organizations face a straightforward question: how quickly can they adopt quantum-resistant attestation while keeping existing workflows intact?

Quantum-Safe File Attestation removes the integration burden. It runs as a pay-per-use tool on AgentPMT, requires no infrastructure changes, and produces attestation packages that any system can verify with nothing more than the public key. Five credits per attestation. Zero excuses for waiting.
