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
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
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 ,
Those who do not read are no better off than those who cannot.
