With Simplelogin integration Proton does PGP encryption because effectively all emails are forwarded by a simplelogin address. I have just tested to be sure, and I can confirm it is the case. I agree though that this only protects “my side”, which is why I said that it doesn’t provide all the PGP features.
Publishing your PGP public key next to your email doesn’t require “wasting a domain” or anything like that
It does if I don’t have any key that I use for emails. My key(s) is bound to the Proton account with the other domains I use, so for this domain I would need to either add it (back) to Proton (easier option, but “wastes” a domain) or just generate and manage a key myself, that I can then even add manually to Proton, but I didn’t bother doing this just yet. I am not going to use any other public key I have because I wanted specifically to keep this domain separated from my identity.
I just thought it was amusing that you didn’t seem to actually follow your own advice.
FWIW, I do follow the described setup for everything personal, which is what matters to me. As I said, ~1/2 months ago I did have my PGP key because I enrolled the domain into Proton, which if anything is a testament to how annoying it is having to manage keys myself (which I already do for signing commits etc.). Maybe I will spend some time to polish the setup, eventually.
The biggest items on the graph are all out of bounds accesses, use-after-free and overflows. It is undeniable that memory safe languages help reducing vulnerabilities, we know for decades that memory corruption vulnerabilities are both the most common and the most severe in programs written in memory-unsafe languages.
Unsafe rust is also not turning off every safety feature, and it’s much better to have clear highlighted and isolated parts of code that are unsafe, which can be more easily reviewed and tested, compared to everything suffering from those problems.
I don’t think there is debate here, rewriting is a huge effort, but the fact that using C is prone to memory corruption vulnerabilities and memory-safe languages are better from that regard is a fact.
