I really love the new version of the Nitrokey with all its awesome new features. I’m using the Nitrokey Pro 2 for quite a long time now and I’m very satisfied. I also appreciate the decision to use Rust programming language and the Trussed library. The only thing I'm a bit concerned about is that it’s written: “Very much WIP. Actively developed. Unstable APIs.” on the Trussed project page and that there are only five contributors. My questions are: 1. Is the library and with this the Nitrokey 3 “stable and secure enough” for our critical infrastructure? 2. How do you plan to handle constantly changes in the cryptographic library? 3. Was there an official audit of the library? 4. Do you plan to offer future versions of the key using the LPC55S6x?
