The first item is certainly the portal type. The second item is the user's public key. The third item is the signature. The signature seems to be a signed message digest, so the whole message must be reconstructed in order to verify a signature (Is it Schnorr-SHA256?)
One possible way of adding additional fields to the certificate (i.e. registration time) is to append these information to the portal type or the user name, but I don't know how ZeroNet interprets the certificate.

The first
%sis obviously the user's public key. After that it is the portal type. The second%sis the user name.Certificate format:
