Victor tours some of Postgres’s many options along with their pros and cons before showing off an extension he’s built to help you generate IDs too.

What pgcrypto Does — It made us laugh, but sadly we had to change Paul’s actual ‘crypto’ related headline to avoid hitting the spam filters ;-) Nonetheless, he takes a practical, high level look at the options pgcrypto presents for encrypting and decrypting data inside a database.
