Hello, we tried to generate a digital signature with PKCS#11:
We successfully loaded the PKCS#11 module. We started the signature process, added the PIN and after we tried to save the document we received the following error message:
"Error encountered while signing: unsupported algorithm."
Is there any information about PKCS#11 supported algorithms?
Is there any update on this problem please ?
Is this really supposed to be supported ?

Did you solved this problem. We have now the same problem. I have a new eID. But the certificates were not longer recognised. So I re-Installed Adobe Acrobat Reader DC. The certificate for signature is now accepted and tested (5 green check marks). But at the end of the process to sign a .pdf document the error appears: (dutch:) “Fout aangetroffen tijdens ondertekenen: Niet-ondersteund algoritme” (free translated:)”Error encountered while signing: Unsupported algorithm”. What can I do? Please answer.
The problem is solved. Solution : configure Acrobat Reader without pkcs#11 module.
If this module has already been linked, the already linked module must therefore be uncoupled again.
After unlinking, restart Acrobat Reader and try signing again.
BELGIUM uses software called eID middleware that communicates with the card for Windows. In the past Acrobat Reader could not use this middleware and Acrobat Reader needed the pkcs11 module to do the communication with the card. Recently, ADOBE has made the necessary changes so that READER can work with the middleware.
The pkcs11 module has now basically become optional within Acrobat Reader.
THanks for the help. Could you explain further how to set up the eid for acrobat since "ADOBE has made the necessary changes so that READER can work with the middleware." ?
If it is not with the pkcs#11 anymore, how should I configure the card reader to work with Acrobat for digital signatures?
