//! PGP cryptography primitives backed by rPGP.
//!
//! Proton's key model is layered: an address key (unlocked from the account
//! passphrase) decrypts a share/node *passphrase*, which in turn unlocks the
//! locked node key, which decrypts names, hash keys and content keys. This
//! module exposes the small set of operations that chain implements.
