Implement AuthenticationTagMismatchException exception #75160

vcsjones · 2022-09-06T19:45:00Z

This introduces a new AuthenticationTagMismatchException for AEAD ciphers to throw during decryption when the authentication tag produces a mismatch.

Previously for Android, we were assuming any failure meant "auth tag mismatch". This changes the native shim to properly catch and handle the Android AEADBadTagException.

Closes #67082

Draft to get a run through CI. Android is very unhappy in my local dev.

The x86 and x64 Android legs passed. The ARM64 seemed to crash. I also cannot get the ARM64 tests to run locally, but that's true even on main, so I don't think I introduced any incorrect behavior.

Marking as ready for review, then.

@bartonjs @jkoritzinsky I am having a hard time parsing the results of the Android test runs. I don't see anything in the test results that look like a failure as a result from this change. Can either of you help me confirm that and this is okay to merge?
