I need to support embedded signatures in psignify, which means being able to determine if the message file I've been given has a signature embedded in it. Actually, I don't know if that's true. I think that explicitly specifying embedded signature is a reasonable first pass to make sure that what people think is happening is happening.

Trying to read through Serious Crypto and Crypto Engineering in preparation for "things," but it's looking like I should be focusing more on brushing up on intrusion detection and response, as well as some other security areas.
