In this post, rather than discusing a specific facet of the Social OS API, we'll be looking at some of the components we've used to build Social OS and our Social OS apps.

A classic problem in security is confirming that someone is who they say they are - without keeping a secret code lying around that could potentially be stolen or copied. And the classic solution is to use a password, but rather than recording the password itself for later verification, recording a cryptographic hash of the password. Cryptographic hashes are what are known as trap-door functions, because it is easy to go through in one direction, but very difficult in the other. (The goal is for reversal to be impossible, but we don't live in a perfect world.)
