Welcome to ``cryptography``
===========================
-.. warning::
-
- ``cryptography`` is very young, and very incomplete.
-
``cryptography`` is a Python library which exposes cryptographic recipes and
primitives. We hope it'll be your one-stop-shop for all your cryptographic
needs in Python.

* Poor introspectability, and thus poor testability.
* Extremely error prone APIs, and bad defaults.

+------
+
+``cryptography`` is broadly divided into two levels. One with safe
+cryptographic recipes, "cryptography for humans" if you will. These are safe
+and easy to use and don't require developers to make many decisions.
+
+The other level is low-level cryptographic primitives. These are often
+dangerous and can be used incorrectly. They require making decisions and having
+an in-depth knowledge of the cryptographic concepts at work. Because of the
+potential danger in working at this level, this is referred to as the
+"hazardous materials" or "hazmat" layer.
-Contents
---------
+We recommend using the recipes layer whenever possible, and falling back to the
+hazmat layer only when necessary.
