Not intending to be rude, but being perfectly serious: as a general
rule, if you don't know what an IV is you're probably getting yourself
into a lot of trouble working with low-level crypto libraries.
1. Describe what you're trying to do- I'll be able to help more if I
know what you're actually going for.
2. Try keyczar. It's not perfect, but it's a lot easier to get right.
