I bought a personal certificate from GlobalSign, which I use to sign e-mails.
Now I would like to sign PDF documents as well, and noticed that there has been some progress in the European Union that makes it easier to obtain a certificate for so called qualified signatures. I’m aware that I would need another GobalSign certificate to issue qualified signatures.
Never the less, the eSignature validation tool of the European Commission is reporting my PDF signature as invalid (not as not qualified)
Unable to build a certificate chain until a trusted list!
The result of the LTV validation process is not acceptable to continue the process!
The certificate chain for signature is not trusted, it does not contain a trust anchor.
Now, for configuring web servers I’m used to chaining certificates, but with LibreOffice or Firefox I do not see any option to do so. Also, isn’t the point of using trusted CAs that you don’t need to provide the anchor?
The validation tool is able to list the chain, actually:
[My full name]
GlobalSign GCC R3 PersonalSign 2 CA 2020
How would I go about signing PDFs with LO that pass as valid? Thanks a bunch!
