________________________________
This begins the voting period for Version 3 of ballot SC27: Version 3 Onion Certificates

Purpose of Ballot:

This ballot will permit CAs to issue DV and OV certificates containing Tor onion addresses using the newer version 3 naming format.

In ballot 144, later clarified by ballots 198/201, the Forum created rules for issuing EV certificates containing onion addresses. A primary reason for requiring EV level validation was that onion addresses were cryptographically weak, relying on RSA-1024 and SHA-1. More recently a newer "version 3" addressing scheme has removed these weaknesses. For much the same reason that EV certificates are not always a viable option for website operators (e.g. sites operated by individuals), many onion sites would benefit from the availability of DV and OV certificates for version 3 onion addresses.

The Tor Service Descriptor Hash extension required in the EV Guidelines to contain the full hash of the keys related to the .onion address is no longer needed as this hash is part of the version 3 address.

Older version 2 onion addresses are still in use, so this ballot does not remove the existing EV Guidelines requirements for onion names.
