[2.x] iCloud (TouchID) userHandle is without dash

[stoutZero]

PHP & Platform

8.3.6 - macOS 14.4.1 aarch64

Database

PostgreSQL 14.11

Laravel version

11.5.0

Have you done this?

• [X] I have checked my logs and I'm sure is a bug in this package.
• [X] I can reproduce this bug in isolation (vanilla Laravel install)
• [ ] I can suggest a workaround as a Pull Request

Expectation

When I use 1Password / my macbook's TouchId, as long as I have registered it in the system, I should be able to login.

Description

When using 1Password as a Passkey, 1Password seems to be sending the userHandle in the format that this package expects, which is without dash, e.g.: 6943324022c046d395de29ceda194b63

Which will be validated in \Laragear\WebAuthn\Assertion\Validator\Pipes\CheckCredentialIsForUser@validateId like so:

hash_equals(Uuid::fromString($validation->credential->user_id)->getHex()->toString(), $handle);
// using the userHandle 1Password provided, the line above becomes:
'6943324022c046d395de29ceda194b63' === '6943324022c046d395de29ceda194b63';

But my MBP's TouchID seems to sent userHandle with dash, i.e.: 69433240-22c0-46d3-95de-29ceda194b63 the hash_equals above effectively becomes:

'6943324022c046d395de29ceda194b63' === '69433240-22c0-46d3-95de-29ceda194b63';

This makes logging-in using my TouchID to be impossible, I reckon other people also can not login.

Right now this issue is not a problem in my projects, as I am using this workaround in my WebAuthnLoginController.php:

    public function login(AssertedRequest $request)
        : \Symfony\Component\HttpFoundation\Response
    {
        // hacky workaround =>
        $userHandle = $request->json()->get('response.userHandle');

        $request->json()->set('response',
            [
                'userHandle' => Str::replace(
                    '-', '', $userHandle ?? ''
                )
            ]
            + $request->json('response')
        );

        $user = $request->login();

        // ...
    }

But someone might want to address this issue

Reproduction

// sorry, don't have the time to make a repro, feel free to just close this issue :)
// the issue itself is easily fixable on userland, with a little hack.

This should be fixed by simply checking if the user handle sent by the Authenticator is an UUID, and normalize it, on the pipe that checks that.
