I am trying to get a cert that I can use to digitally sign PDFs. I have seen there is a thread from Feb which says this is not possible with Let’s Encrypt (link below). Is that still the correct?
Even if there is no direct functionality within Lets Encrypt, is it possible to export the Lets Encrypt x509 cert into a PDF app that allows signing? (ie export x509 and upload that as signature file into PDF app)
If not possible at all in Lets Encrypt, many thanks for alternative free digital signature providers (cacert.org I think is one, but others?)
