Thank you very much for your answer! I'm sorry that I wasn't clear about it, but I am more interested if it is possible to use GPG to do the basic things here (not necessary for an election), i.e. to have a user blind a small text file with some GPG-command, then if it is possible for the signer to sign the blinded text file with some GPG-command, and finally if the user would be able to unblind this signed text file now also containing a signature from the signer.
I guess this is not possible to do with GPG, right? >From what I've read it seems like GPG internally is using blinding to avoid RSA timing attacks, but I guess it is not possible for a user of GPG to use those functions in a similar way as I describe above. I've looked a bit at CryptoBallot and all the crypto stuff seems to be done in the Go language. I've also looked at PseudoID which seems to be coded in Python and JavaScript, i.e. none of CryptoBallot or PseudoID seems to use GPG in any way. Maybe I should try see if I can borrow some code from CryptoBallot or PseudoID to do this, or in best case if someone knows some other project that fits better so I can set up a simple prototype of the system myself?

What you went on to describe sounds quite a bit like CryptoBallot [0], [1]. [0] .
