OK, normally when I hear about someone who doesn't know crytpography or Rust writing Rust code and rolling their own cryptographic protocol, I'd almost certainly not going to use their code... but... Wang Lu seems to be the real deal, just picking up these skills along the way. Their highly experimental hardware password manager, which is not open source hardware nor software, sounds like it's a pretty decent design. If it actually does what is described, I am impressed.

It'll be interesting to follow along and see if it turns out to be an even more hardcore password manager than the #Signet. Of course, there's no proof that any of this code exists and works, so it could all be vaporware. We won't know unless it's released (in either source of binary form).
