Bug 233371 – Add headers for [_WKWebAuthenticationPanel makeCredentialWithClientDataHash] and [_WKWebAuthenticationPanel getAssertionWithClientDataHash]

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[[e-mail]]

This is a followup to: https://bugs.webkit.org/show_bug.cgi?id=233216

Summary:
In order to avoid needing to make and coordinate changes to ASC to support new fields or changes within ClientDataJSON and to maintain a single source of truth, calls to ASC from WebKit will contain a precomputed ClientDataHash.

In order to use these new methods, they must be added to _WKWebAuthenticationPanel.h

r=me if you switch to WK_<MAC/IOS>_TBA in the availability macros.

> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.h:129
> +- (void)makeCredentialWithClientDataHash:(NSData *)clientDataHash options:(_WKPublicKeyCredentialCreationOptions *)options completionHandler:(void (^)(_WKAuthenticatorAttestationResponse *, NSError *))handler WK_API_AVAILABLE(macos(12.0), ios(15.0));

This isn't true -- we already shipped macOS 12 and iOS 15 without these methods. Usually we use "WK_MAC_TBA" and "WK_IOS_TBA" until we are close to a release.

> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.h:131
> +- (void)getAssertionWithClientDataHash:(NSData *)clientDataHash options:(_WKPublicKeyCredentialRequestOptions *)options completionHandler:(void (^)(_WKAuthenticatorAssertionResponse *, NSError *))handler WK_API_AVAILABLE(macos(12.0), ios(15.0));

Ditto.

> Tools/TestWebKitAPI/Tests/WebKitCocoa/_WKWebAuthenticationPanel.mm:1932
> +        EXPECT_WK_STREQ([response.rawId base64EncodedStringWithOptions:0], "SMSXHngF7hEOsElA73C3RY+8bR4=");

Curious if this rawId has a meaning you could reference, similar to the comments in the GetAssertionLAClientDataHash test, below.

> Tools/TestWebKitAPI/Tests/WebKitCocoa/_WKWebAuthenticationPanel.mm:2117
> +        // echo -n "example.com" | shasum -a 256 | xxd -r -p | base64

These comments are super helpful. I wonder if there is a similar thing you could say about the raw ID above?

Wish I could've made it a slick bash command but converting from x9.63 to something openssl understands and back was involved.
