dnscrypt-proxy provides local service which can be used directly as your local resolver or as a DNS forwarder, encrypting and authenticating requests using the DNSCrypt protocol and passing them to an upstream server.

The DNSCrypt protocol uses high-speed high-security elliptic-curve cryptography and is very similar to DNSCurve, but focuses on securing communications between a client and its first-level resolver.

While not providing end-to-end security, it protects the local network, which is often the weakest point of the chain, against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.

This document explains how to create a new PGP key and break it in, gradually having it replace the old key.

User and password verification with two-factor authentication isn't as easy to use as plain old user and password, but with smartphones it comes very, very close. At the same time, the security benefits from having another secret stored on a different terminal are massive. Users' accounts aren't necessarily compromised if their passwords are.

In my mind, two-factor authentication is one of the least tedious things you can add that adds the most security to user accounts.

"But it's a pain to add to your application, right?"

No! Just take a look at main() in this example that uses only the Python standard library
