Good point. I'd word it something like this: A Word of Warning This library exposes a very complex API. It is intended for expert users only. If you have any doubts about your knowledge of the underlying cryptographic primitives, we strongly recommend against using this library. Doing so without advanced knowledge of cryptography could compromise your security. Instead, we recommend you use a high-level crypto library, such as Keyczar or NaCl, both of which are designed to "just work" in the hands of developers who lack specialize expertise in crypto.
