ChaindocPAdES Signature Verification
Validate PDF Advanced Electronic Signatures (PAdES) with EU DSS compliant verification. Upload your signed PDF to verify cryptographic integrity, certificate validity, and signature authenticity.
Verify PDF Signature
Upload a signed PDF document to validate its digital signatures using EU DSS verification standards.
What is PAdES Verification?
PAdES (PDF Advanced Electronic Signatures) is a set of restrictions and extensions to PDF and ISO 32000-1 making it suitable for Advanced Electronic Signatures. Our verification service uses EU Digital Signature Service (DSS) to validate signatures according to ETSI EN 319 142 standards.
Signature Integrity
Verify that the PDF document has not been modified after signing using cryptographic hash validation.
Certificate Validation
Check the signing certificate chain, validity period, and revocation status against trusted certificate authorities.
Timestamp Verification
Validate embedded timestamps to prove when the signature was created and ensure long-term validity.
eIDAS Compliance
Verification follows EU eIDAS regulation standards for qualified electronic signatures and seals.
Supported Signature Formats
Our verification engine supports all PAdES baseline profiles defined by ETSI standards, ensuring comprehensive validation for any compliant PDF signature.
PAdES-BASELINE-B
Basic Electronic Signature profile providing the minimum requirements for an advanced electronic signature.
PAdES-BASELINE-T
Trusted timestamp added to the signature, proving the existence of the signature at a specific point in time.
PAdES-BASELINE-LT
Long-term validation data embedded, including certificates and revocation information.
PAdES-BASELINE-LTA
Archive timestamp for long-term archival, ensuring validation remains possible over extended periods.
