iOS E-Mail Clients


pretty Easy privacy (abbreviated as p≡p) is a cyber security solution which protects the confidentiality and reliability of communications for citizens, for public offices and for enterprises. It provides end-to-end cryptography through software that you install on your desktop or your tablet or your phone. To exchange secure messages, you and your communication partner both need to install p≡p on your devices (e.g. computer, smartphone). After the installation you can start exchanging messages without any configuration. All messages (except the very first one) will be secured by p≡p. You can see this by the Privacy Status, which will be yellow (Secure).
