Unable to add my yubikey - modhex analysis fails

Hey,

I have a yubikey that is working fine in general (on other sites) but not with this extension.

It contains characters, that the modHex preg_match in this extension does not seem to like. Here's a screenshot from the yubico demo web site with pertinent parts:

It's a Yubikey 5 NFC if that's relevant.

[TASK] Remove usage of utf8_encode

[TASK] Register icon using Icons.php

TYPO3 11.4 only

[TASK] Use alternative API to replace curl_multi calls
