MD5 as implicit default digest for *digestmod* is deprecated.
+.. function:: digest(key, msg, digest)
+
+ Return digest of *msg* for given secret *key* and *digest*. The
+ function is equivalent to ``HMAC(key, msg, digest).digest()``, but
+ uses an optimized C or inline implementation, which is faster for messages
+ that fit into memory. The parameters *key*, *msg*, and *digest* have
+ the same meaning as in :func:`~hmac.new`.
+
+ CPython implementation detail, the optimized C implementation is only used
+ when *digest* is a string and name of a digest algorithm, which is
+ supported by OpenSSL.

An HMAC object has the following methods:
