This is beta software. It contains many remaining bugs!
Android Privacy Guard (APG) is a OpenPGP implementation for Android.
This is a fork based on the original APG to introduce more features and a new user interface.
Be careful editing your existing keys, as they WILL be stripped of certificates right now.
Also: key cross-certification is NOT supported, so signing with those keys will get a warning when the signature is checked.
Install K-9 Mail for the best integration, it supports APG for PGP/INLINE and lets you directly encrypt/decrypt emails.
It is recommended that you install OI File Manager to be able to use the browse button for file selection in APG.
First you need some keys. Either import them via the option menus in "Manage Keys" and "My Keys" or create them in "My Keys".
Please report it in the issue tracker of APG.
