Request for crypto review: We've been working on an explainer series for how to build end-to-end encrypted P2P social networks. It was very hard for me to figure out /conceptually/ what pieces needed to go where and fit with others, so we made this series ( http://gun.js.org/explainers/data/security.html ) on how to use Public/Private key pairs, PBKDF2, Proof of Work, AES, and Digital Signatures. Anybody up for reviewing it and telling me if this is the right combo/structure?
