Verification Results

Back

Verification was un-successful:

An error has occurred whilst verifying the document, possible reasons include:
* The document may not be a valid PDF
* The document may not contain any standard PDF signatures

If you have supplied a PDF document then our support team can check that it is compatible by sending it (zipped please) to support@ascertia.com with a short note explaining that an error occurred while verifying the PDF within the Ascertia website demo system.
Note:

  • Server-side verification uses a flexible OASIS DSS API that can define how ADSS Server should verify the signature and what evidence information should be returned, e.g. CRL/OCSP revocation information, certificate path information, etc.
  • Using the Verification Service API, the client application can request the Verification Service to return a range of information about the signer, the issuing Certification Authority or the information gathered as part of the verification process. This includes CRLs, OCSP responses, timestamps, Quality information, certificate extension information etc.
  • All verification service responses are signed by the Ascertia ADSS Verification Server so that clients can see that these are genuine messages from a trusted authority and they have not been changed.
  • The ADSS Verification Server not only ensures that the document has not been changed since signing and that the signer’s credentials are valid (not expired, not revoked and issued by a trusted CA) but can also report on the quality level of the signature and the associated certificate quality level – see this information on PEPPOL.
