Verifiable signatures

QRINTEX Signer

Documents outlive systems. QRINTEX Signer creates portable, long-term verification evidence for contracts, approvals, transactions and operational records that may need to stand up in audits or disputes decades later.

How it works

Sign once. Protect the evidence for years.

1
Fit existing trust infrastructure
Deploy alongside existing HSM, IAM, document and compliance workflows while supporting preparation for NIST-aligned post-quantum migration.
2
Create portable evidence
Every important document or transaction receives durable verification evidence for long-term legal, operational and audit purposes.
3
Reduce future dependencies
Verification can later run locally, independent of the original platform, vendor-operated cloud or live certificate-checking service.

Capabilities

Long-term evidence for important decisions.

Contract and document evidence
Preserve verifiability for PDF, Office and binary documents that may become audit or dispute evidence years later.
Transaction evidence
Make financial transactions, database commits and API requests independently verifiable without relying on a single intermediary system.
Software and firmware assurance
Sign build artifacts, firmware and packages through CLI, REST API and CI/CD integration to support long-term supply-chain evidence.
HSM-compatible deployment
Use PKCS#11-compatible HSMs so private keys remain in controlled, tamper-resistant hardware.
High-volume evidence workflows
Batch signing for automated pipelines and heavy operational evidence workloads.
Offline verification
Verification can be self-contained: no network call, OCSP or CRL dependency is required for the proof model.

Get Started

Make today’s approvals defensible tomorrow.

We map where long-term legal verifiability is needed and show whether a NIST-aligned approach, patented QRINTEX verification technology or a hybrid model fits best.
