Signatures

Signature commands inspect or remove digital signatures present in a PDF.

pdfcpu validates signature integrity, reports available trust evidence and performs a best-effort local assessment.

Signature validation is under active development. The current implementation focuses on:

• signed byte ranges
• CMS/PKCS#7 processing
• signer and certificate extraction
• best-effort checks against the configured local certificate store and available revocation information

This is not a legal-validity, eIDAS, enterprise policy, or full long-term validation statement.
