Bulk Digital Signatures

Batch Cryptographic Signing USB Token & PFX LTV & Timestamping

Signing hundreds of PDF contracts, invoices, or legal filings one by one in desktop viewers is exhausting, prone to missed pages, and requires repeatedly inserting PINs and manually dragging signature boxes for hours.

Automatically sign entire directory trees of PDFs in a single automated batch run using physical hardware tokens (MoldSign, STISC, SafeNet, Gemalto, eIDAS-compliant USB dongles) or software certificates (.pfx / .p12). Features smart text anchor positioning (e.g. automatically finding the word 'Director' or 'Signature' on the last page) or fixed coordinate placement, with RFC 3161 cryptographic timestamps and Long-Term Validation (LTV).

Select a certificate type and signature anchor to preview cryptographic placement in real time:

✓ Cryptographically Validated — PDF Content Protected from Tampering
  • 1Select your digital certificate source: insert your USB Token or load your .pfx file.
  • 2Choose signature positioning: fixed coordinates or Smart Text Anchor (e.g. searching for 'Signature' on the final page).
  • 3Optionally enable RFC 3161 cryptographic timestamping and LTV (Long-Term Validation) for permanent legal validity.
  • 4Select your input directory containing multi-level folders of PDF documents.
  • 5Start the batch process — the engine securely applies certified digital signatures and exports the files, preserving folder trees.

❓ Can I remove digital signatures without breaking document text or visual appearance?

Yes. DocInspector safely strips cryptographic signature locks and restriction dictionaries while leaving all underlying text, images, and visual representations 100% intact.

❓ Does DocInspector support physical USB cryptographic tokens?

Yes. It works seamlessly with PKCS#11 hardware USB tokens (MoldSign, STISC, SafeNet, eIDAS-compliant devices) and standard PFX/P12 certificate stores.

❓ Is signature verification executed completely offline?

All validation, certificate path inspection, and lock stripping happen 100% locally on your machine with zero cloud uploads.
