<!--Description

⚠️ **CODE BARELY COMPILES**

⚠️ **CODE IS NOT TESTED**

⚠️ **DO NOT USE (YET)**

⚠️ **CURRENTLY UNLIKELY TO WITHSTAND Y2Q**

Forked from the [`u2f`](https://crates.io/crates/u2f) crate, which (as of this writing) has not been updated in years.

This is still a work in progress as I journey through the existing code and adapt it to use up-to-date dependencies, compile, test, and fit my style. I also have the ambition to not just cover U2F, but also the FIDO2 spec, but we'll see how that goes. ;)

### Goals

Here are some of the biggest challenges:

[ ] Audit the `u2::util::asn_length()` function, as it may or may not be doing its job correctly. 

[ ] Get this crate aligned with the U2F and FIDO2 standards such that a web dev could use this crate and accept both U2F- and FIDO2-compatible authentication from users (https://www.w3.org/TR/webauthn/).
