Detailed Description

HMAC (Keyed-Hashing for Message Authentication) Python module.

Implements the HMAC algorithm as described by RFC 2104.

Return the hash value of this hashing object.

This returns a string containing 8-bit data.  The object is
not altered in any way by this function; you can continue
updating the object after calling this function.

Create a new hashing object and return it.

key: The starting key for the hash.
msg: if available, will immediately be hashed into the object's starting
state.

You can now feed arbitrary strings into the object using its update()
method, and can ask for the hash value at any time by calling its digest()
method.
