* Encrypt tokens on the way out and decrypt on the way in This isn't a security feature related to tokens specifically; it's so that we can discard cryptographically bad tokens before we ever hit the DB. This way we can't pass through a DDoS to the database due to fetching obviously invalid token values. I'm using base58 to encode the resulting value as there aren't great base62 options, and allowing base64 / and + values can hamper usability by creating copying/highlighting breaks.
