Ok, maybe we should make a distinction between, let's say the plumbing code and algorithms. Rust could help with the former. According to some comments I've read here it seems OpenSSL is using it's own abstraction of malloc/free (not that I have actually read the code). I suppose that this part of the code would be a suitable candidate for unsafe code with special extra care taken, then the rest of the algorithm does not not to be unsafe code. If you watch the video you might understand better what I mean : the ARC is unsafe but provide you with a safe abstraction for you to use in the checked part of the language.

Of course such a project must require extra scrutiny on all level and Rust does not resolves all the problems. I'd say pick your battles. Rust provide some interesting middle ground between C/C++ and a completely different language like Ada.
