  • Wireguard is most reliable in terms of security. For censorship resistance, it’s all about tunneling it in a way that looks indistinguishable from normal traffic

    Domain or IP doesn’t make much of a difference. If somebody can block one they can block the other. The trick is not getting flagged. Domain does make it easier to administer though with stuff like dyndns, but then you also need to make sure eSNI is available (especially if it’s on hosting) and that you’re using encrypted DNS lookups



  • There’s also a big difference between published specifications and threat models for the encryption which professionals can investigate in the code delivered to users, versus no published security information at all with pure reverse engineering as the only option

    Apple at least has public specifications. Experts can dig into it and compare against the specs, which is far easier than digging into that kind of code blindly. The spec describes what it does when and why, so you don’t have to figure that out through reverse engineering, instead you can focus on looking for discrepancies

    Proper open source with deterministic builds would be even better, but we aren’t getting that out of Apple. Specs is the next best thing.

  • And while they tried to DRM it, the DVD standard still ended up having to maintain compatibility across all readers and discs, but for bluray they regularly deprecate older readers who no longer can play newer movies because new releases use new encryption keys which the old readers don’t have access to (and for this reason the PS consoles are the best bluray movie players because Sony keeps them updated)
