Doing crypto with the Security APIs is rather complex and unintuitive.
(I think they're tied with CoreAudio as the most difficult APIs in OS
X.) There are a lot of things you need to drop down to lower levels,
like the almost-undocumented CDSA, for.
I did a bunch of this last year and extracted it into a framework,
which you can either use as-is or scan for tips.

FYI, the obscurely-named apple-cdsa list is the best place to discuss
OS X or iPhone security/crypto.
