+Bindings
+========
+
+.. currentmodule:: cryptography.hazmat.bindings
+
+``cryptography`` aims to provide low-level CFFI based bindings to multiple
+native C libraries. These provide no automatic initialisation of the library
+and may not provide complete wrappers for its API.
+
+Using these functions directly is likely to require you to be careful in
+managing memory allocation, locking and other resources.

+OpenSSL Binding
+===============
+
+.. currentmodule:: cryptography.hazmat.bindings.openssl.binding
+
+These are `CFFI`_ bindings to the `OpenSSL`_ C library.
+
+.. class:: cryptography.hazmat.bindings.openssl.binding.Binding()
+
+    This is the exposed API for the OpenSSL bindings. It has two public
+    attributes:
+
+    .. attribute:: ffi
+
+        This is a :class:`cffi.FFI` instance. It can be used to allocate and
+        otherwise manipulate OpenSSL structures.
+
+    .. attribute:: lib
+
+        This is a ``cffi`` library. It can be used to call OpenSSL functions,
+        and access constants.
