Is this on a road map in a foreseeable future?

Wondering about the same as Greg. Is support on the roadmap?

Length can't be less than zero! :-)

If this is being tracked in Radar, can you reference it here so we can (hopefully someday) get rid of this hack?

It's sad that these still don't pass. Are we missing features that prevent these from working? Will Step 2 (or some future step) get these passing?

I don't know the answer for now. I am hoping adding PKCS8 support can help us pass these tests.

It looks like that those Yosemite bots are not configured to have internal SDK. I will skip those test cases for Yosemite specifically.

None of webkit.org bots have internal SDK. WebKit and its tests are expected to work in an open source build.

Are you saying these tests should pass on El Capitain and newer? Then I think skipping for Yosemite is okay.

If these tests require some kind of internal SDK feature, we need to create a WebKitSystemInterface implementation that can be used by OpenSource builds.

This patch looks good, but I noticed that potential buffer overrun. I think you need to fix that before landing, and please double-check that we don't have the same mistake elsewhere in the crypto stuff.

r- to correct the buffer overrun issue.

If "keyData.size() == headerSize", and then you dereference as "keyData[headerSize]" we have a problem.

You might want to double-check the other places you use this code, because I might not have noticed this previously.
