How Long-Term Validation Works
Audit signature properties and compliance structures in 3 simple steps.
Select PDF
Load your PDF document containing cryptographic signatures.
Standard Audit
The sandbox checks validation certificates and revocation files inside DSS dictionaries.
Compliance Report
Inspect signature parameters and export JSON audit results.
Why validate signature longevity?
Long-Term Validation (LTV) ensures that digital signatures remain legally verifiable even after this signer's certificate expires or this issuing CA database goes offline. This tool validates that OCSP responses, CRL directories, and root trust anchors are completely embedded within this Document Security Store (DSS) catalog structure.

Structural Auditing
Scans low-level PDF dictionary structures for /DSS, /Sig, /OCSP and /CRL keys.
Verification Logs
Inspects public key size, signing times, and signature details.
Security & Archiving
Perfect for archiving compliance verification, completely runs in your local sandbox.
Frequently Asked Questions
Find fast answers to common questions about LTV verification.
Q.What is LTV?
LTV stands for Long-Term Validation. It means a PDF signature includes all cert chain revocation data (CRL/OCSP) needed to verify it offline years later.
Q.How can I fix a non-compliant signature?
Open the file in Adobe Acrobat, right-click the signature, and select 'Add Verification Information' to fetch and embed the cert chain.
Q.Are my validation files secure?
Yes. All validation checks run offline inside your browser sandbox. No document binaries or passwords are sent to any servers.
Q.Does this validator modify my files?
No. This tool is read-only. It scans document objects to audit compliance, generating report logs without writing to the PDF.
