OpenKeychain: Easy PGP




    OpenKeychain helps you communicate more privately and securely. It uses encryption to ensure that your messages can be read only by the people you send them to, others can send you messages that only you can read, and these messages can be digitally signed so the people getting them are sure who sent them. OpenKeychain is based on the well established OpenPGP standard making encryption compatible across your devices and systems. For a list of compatible software for Windows, Mac OS, and other operating systems consult

    Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android smartphone. It also helps you find others’ keys online, and exchange keys. But its most frequent use is in using those keys to encrypt and decrypt messages.

    If your looking for an easy app to encrypt and decrypt this is perfect. but as far as exporting private keys/public keys there is no way lol but you can still import your old key from ur pc and use it only as an encriptor/decryptor which is good ...

    This application does not let you export your secret key in a standardized way to import it on other devices, e. g. a desktop PC running Linux. Therefore I can't recommend using it for creating new keys, since it creates a vendor lock-in to this application and the Android OS.

    Excellent app. I use it nearly every week when my computer is not next to me.
