GnuPrivacyGuard (GPG) brings GnuPG, the most trusted name in encryption, to Android. Easily encrypt, decrypt, sign and verify files of any kind, just by sharing them to GPG. This app aims to provide a complete, integrated crypto toolkit integrated into the Android experience. GPG provides solid encryption for files private, and for verifying that files are who you think they are. It includes optimizations to make it operate many times faster than other encryption packages.

GPG provides an integrated experience, so clicking on OpenPGP files "just works". You can also share files to GPG to decrypt, encrypt, sign, or verify them. GPG will respond when you click on a OpenPGP fingerprint URL (one that starts with openpgp4fpr:). GPG also gives you complete command line access to the entire GnuPG suite of encryption software. We are working on Android integration for all of GnuPG's crypto services, including OpenPGP, symmetric encryption, and more.

***Setup***
Before using GPG, be sure to launch the app and let it finish its installation process. Once it has completed, then you're ready to use it!

If you want to use the command line, the easiest way to get started with GPG is to install Android Terminal Emulator. GPG will automatically configure Android Terminal Emulator as long as you have the "Allow PATH extensions" settings enabled. Get the Android Terminal Emulator at https://play.google.com/store/apps/details?id=jackpal.androidterm

CyanogenMod Privacy Guard must be disabled for this app to work!

***Features***
★ TRUSTED SECURITY: GnuPG already seamlessly integrates into Mac OSX (GPGtools), Windows (gpg4win), GNU/Linux, Debian, Ubuntu, Fedora.
★ OPEN STANDARD COMPLIANT: Full OpenPGP implementation following RFC2440 and RFC4880

    Can't even seem to import a public key. APG seems much more useful right now.

    No way to encrypt text files and keep it a text file? What's wrong with the Dev? Stupid sounds like uninstall and reporting them, this is a bogus app

    When I import my private key, it asks for a password, I never set up the key for a password based lock on the key, how do I import it?

    waiting for integration with the native mail app. Please don't use K-9, the majority is moving away from Exchange 2003/2007. Changing the review of course once this happens! :)

    It is a great app but every time I put in a acceptable passphrase it says failed to generate key any advice on what may help
