GnuPrivacyGuard extends the gpgcli command line tool to bring an integrated privacy engine to your Android. It gives you command line access to the entire GnuPG suite of encryption software. It also serves as the test bed for complete Android integration for all of GnuPG's crypto services, including OpenPGP, symmetric encryption, and more.
GPG is GNU’s tool for end-to-end secure communication and encrypted data storage. This trusted protocol is the free software alternative to PGP. This app is built upon GnuPG 2.1, the new modularized version of GnuPG that now supports S/MIME.
GPG aims to provide an integrated experience, so clicking on PGP files should "just work". You can also share files to GPG to encrypt them. GPG will also respond when you click on a PGP fingerprint URL (one that starts with openpgp4fpr:).
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. The easiest way to get started with GPG is to install Terminal Emulator. GPG will automatically configure Android Terminal Emulator as long as you have the "Allow PATH extensions" settings enabled.
