$ gpg --with-colons --list-config curve cfg:curve:cv25519;ed25519;cv448;ed448;nistp256;nistp384;nistp521;brainpoolP256r1;brainpoolP384r1;brainpoolP512r1;secp256k1
How would Kleopatra know that cv* is for encryption, ed* is for signing, and all other curves are for both uses? Or are the cv/ed prefixes a (de facto) standard?
