There is now an update of the webauthn package available at GitHub. In short, it has a much richer support of cryptographic algorithms, and is based on the new native JSON support of NaviServer (including safe quoting on JSON output). Previously, just ES256 was supported, now we have also RS256 and the modern OKP. This is possible due to the new crypto support in NaviServer. This features will be available in NaviServer 5.1. To use it, one has currently to use the tip version of NaviServer from GitHub. The next days, i'll update OpenACS.org with the new code base.
More details about the recent changes are in the links below.
All the best
