Document and File Certification with Post-Quantum Digital Signatures
Generate tamper-proof digital certificates for any uploaded file using post-quantum cryptography. This workflow guides the user through uploading or selecting a file via the File Management tool, then signs it with the Quantum-Safe File Attestation tool using ML-DSA-65 (Dilithium3) post-quantum digital signatures via hardware security module. Returns a verifiable attestation package containing a cryptographic manifest, digital signature, and verification bundle with a downloadable certificate link. Use cases include regulatory compliance document certification, financial audit report signing, legal contract attestation, intellectual property timestamping, medical record integrity verification, insurance claim evidence certification, notarized document equivalents, SOC 2 and ISO 27001 audit evidence, HIPAA-compliant document signing, tax filing certification, and tamper-proof archival of sensitive business documents.
Request File Upload
No prompt text was added.
Upload File to Storage
Use the File Management tool to handle the user's file. If the user already provided a file_id, use the get action to verify the file exists and retrieve its metadata. If the user needs to upload a new file, use upload_standard (for files up to 10MB) or upload_large (for files over 10MB) to generate a signed upload URL. Guide the user through the upload process and confirm the file_id once complete. If the user is unsure about their file, use the list action to show their existing files.

Workflow preview
What the agent will follow (tools, prompts, and workflow steps).
1. Call tool: File Management (Upload File to Storage). Instructions: Use the File Management tool to handle the user's file. If the user already provided a file_id, use the get action to verify the file exists and retrieve its metadata. If the user needs to upload a new file, use upload_standard (for files up to 10MB) or upload_large (for files over 10MB) to generate a signed upload URL. Guide the user through the upload process and confirm the file_id once complete. If the user is unsure about their file, use the list action to show their existing files. 2. Call tool: Quantum-Safe File Attestation (Create Quantum-Safe Attestation). Instructions: Call the attest_artifact action with the file_id from the previous step. Set the artifact_name to the original filename. Include metadata with file details such as content type, size, and upload timestamp. The tool will sign the file with ML-DSA-65 and return a full attestation package including manifest, signature, and verification bundle.
