Non-functional under Android 11 and 12. For Android versions older than those (at least under 8.1) it does work. This app has almost certainly been abandoned.

Unfunctional

Not working on android 11 due to lack of new storage permission support.

S/MIME certificate cannot be imported in any format, so this app's core feature doesn't work. Might be an issue with modern android versions. This app hasn't been updated since 2015. It's a shame.

I can't import s/mime certificates or verify signed emails on Android 11

Workaround, um es auch auf neuen Android-Versionen, z.B. 11, nutzen zu können: Kopiere die Folder-Struktur "com.flipdog.crypto.plugin" unterhalb von "Android" -> "data" von einer funktionierenden Installation auf das neue Smartphone. Dort erscheinen zwar nicht die in der Struktur bereits vorhandenen Keys, aber jetzt lassen sich alle Keys wie gewohnt importieren. Weitere mögliche Fehlerquelle können die App-Berechtigungen sein. Auf das App-Icon halten, das i-Symbol klicken, in berechtigungen rein und dort alles erlauben.

Simply cannot import a comodo p12 file which works in tbird, ios mail etc. Importing using Android cert installer seems to work, but the cert is invisible to maildroid. I really want to buy maildroid pro, but this inability to import p12 is a real deal breaker.

Only YubiKey support missing.

I am searching for an alternative to K9/OpenKeyChain with Exchange support (EWS) and found in Maildroid a solution. However the crypto plugin is barebone at best and is missing important features compared to OpenKeyChain. I would like to buy Maildroid Pro but this plugin in its current state is not a useful GPG solution and therefore I will not use Maildroid further on.

Good work
