In interpersonal messaging, end-to-end encryption means for public key distribution and verification of its authenticity are needed; the latter to prevent man-in-the-middle (MITM) attacks. This document proposes a new method to easily verify a public key is authentic by a Handshake process that allows users to easily authenticate their communication channel. The new method is targeted to Opportunistic Security scenarios and is already implemented in several applications of pretty Easy privacy (pEp).
