I am currently learning rust and really enjoying everything so far Most intriguing are the almost unbelievably fast web servers you are able to build with rust. I am currently interested in a production-ready (meaning battle-tested & correct) One-Time-Password (OTP) library. Security is of the utmost importance, the library should be reliable if I manage yo implement it correctly.
