pretty Easy privacy (p≡p or pEp) is a pluggable data encryption and verification system, which provides automatic cryptographic key management through a set of libraries (providing p≡p adapters for application developers' used programming languages and development environments) for written digital communications. Its main goal is to make end-to-end encryption the default in written digital communications for all users in the easiest way possible and on the channels they already make use of, including e-mails, SMS, or other types of messages.
