Description
Since upgrading to the Android 8.1 beta, K9 with certificate authentication no longer works. adb logcat shows the following: java.security.UnrecoverableKeyException: Failed to obtain information about private. I'd imagine something must have changed in the Android API to cause this to happen, but I figured I'd open this here before submitting a ticket into the abyss of Android bug reports.
Steps to reproduce
- Set up K9 with certificate auth
- Upgrade to Android 8.1 beta
- K9 can no longer authenticate
Environment
K-9 Mail version: 5.301
Android version: 8.1
Account type (IMAP, POP3, WebDAV/Exchange): IMAP w/ Certificate Authentication

Research direction
Start by reproducing certificate authentication on Android 8.1 and inspect the adb logcat UnrecoverableKeyException. The issue is done when K-9 Mail authenticates successfully with the stated IMAP certificate setup, or the Android 8.1 incompatibility is clearly identified and documented.
