With governments and corporations increasingly infringing upon our privacy, we must take steps to protect our private communications and files. With OpenPGP encryption, you can secure your messages and files to ensure that only the intended recipients are able to read them. OpenPGP is a standardized protocol for protecting data with strong encryption using public key cryptography. It is widely used throughout the world for protecting private exchanges and now it is available on your iOS based mobile device for a nominal price ($1.99 USD).
