@don-vip, this might not be a good fit for Let’s Encrypt because we’re focusing on certificates that can be issued in a completely automated way (which DV certificates for TLS servers can be). That allows us to issue certificates free-of-charge on a large scale. It seems to me that people expect code-signing certificates to incorporate some kind of identification verification of the subject, in the way that OV or EV certs for TLS do. That’s not something that we could do robotically; we’d need to have some kind of offline contact with the outside world to confirm offline identities.
