Good morning
After I have signed a pdf document with Docusign ADVANCED Electronic Signature,
I would like to inspect the details of the electronic signature that was applied.
Since we operate in the European Union, I headed to the documentation provided by the European Commission.
On the page https://ec.europa.eu/digital-building-blocks/sites/spaces/DIGITAL/pages/880312429/eSignature+FAQ
the topic "How do I validate an electronic signature/seal as qualified?" lists 3 methods of validation, but only for Qualified signatures.
Still, I tried each of them.
1) the DSS Validator, available at https://ec.europa.eu/digital-building-blocks/DSS/webapp-demo/validation
does not work well with Advanced Electronic Signatures. When uploading a pdf signed with an advanced signature,
I receive multiple errors such as "Unable to build a certificate chain up to a trusted list!", "The certificate chain for signature is not trusted, it does not contain a trust anchor."
It is true that I use a demo 1-month-trial account, but I've been told that even official Advanced signatures face the same problem.
2) The Signatures tab in Adobe Reader provides very little information. It does not even mention whether the
signature type is advanced or qualified.
3) Does Docusign provide its own online validator ? If it does, please post a link. However, this page suggests the opposite:
https://support.docusign.com/s/document-item?language=en_US&langSet=1&bundleId=xcm1643837555908&topicId=lzc1652878457364.html&_LANG=enus
If you know about any other validation methods, please feel free to enumerate them, I would be happy to hear about alternatives.
Right now, it seems to me that, although I purchased an Advanced Electronic Signature, and applied it to a PDF document,
I cannot really prove the validity of the signature. If our documents will ever be part of a legal dispute, the inability to
proove the validity of the signature may also result in the document (contract) itself being declared void.
Thanks in advance for your support.
