Hi there,

thanks for your (really awesome) Work. I was forced now to remove this Library out of our Composer Project, as we cannot support PHPSecLib2 anymore. Would it be possible for you to switch to V3 or maintain both Versions? (its basically only replace "RSA" with the "PublicKeyLoader::load" Concept from V3, everything else could stay.

Thanks a lot! Christoph

Yes, that doesn't seem like a problem.

Just to clarify, you are expecting to see something along these lines, yes? ... in COSEECDHAtoPKCS, for case RS256, replace:

$rsa = new RSA();
$rsa->loadKey(compact('e', 'n'));
return $rsa->getPublicKey();

with

return (string)PublicKeyLoader::load(compact('e', 'n'));

From my understanding, thats exactly the necessary (and only) change needed for v3, yes.

OK, now released.

Please note the other recent change to prevent replay attacks, which, while upward compatible, requires you to save the $userwebauthn string after calling prepareForLogin and authenticate for it to have any effect.

Thanks, that was really fast :)
