Passkey integration

[kissu]

Hey! Not sure how hard it is to implement some Passkeys or even if it's planned but creating the issue for it. 🙂

I'm almost done with my implementation but it does have a dependency on pilcrow's oslo package. I could create a PR to this repo within a few days.

I think oslo has very good validation functions but this module should also have some utils that create the keys / challenges etc.

I think the minimum would be:

• A composable which handles key and signature creation on client side
• Nitro endpoint that returns credential options.
• Server util for authenticator validation (just like oslo)
• Server util for credential validation (just like oslo)

@Atinux what do you think about the dependency on oslo? Maybe it's better to copy the necessary functions (with reference) instead of depending on the whole package

edit: going on vacation until the 12th. Won't work on this until then

Hello!! By olso, do you mean this package? I look forward to your PR being merged!

[Gerbuuun]

Yes, the webauthn part has the necessary cryptographic key validation functions. Also fully typed and runtime agnostic which is important

[atinux]

If we can avoid importing oslo but having the utilities into this package it would be great so we can be sure that it works on the edge runtime too.

Happy to see your PR @Gerbuuun ❤
