OCB-AES-n reference code based on NIST submission "OCB Mode"
(dated 1 April 2000), submitted by Phillip Rogaway, with
auxiliary submitters Mihir Bellare, John Black, and Ted Krovetz.

This code is freely available, and may be modified as desired.
Please retain the authorship and change history.
Note that OCB mode itself is patent pending.

This code is NOT optimized for speed; it is only
designed to clarify the algorithm and to provide a point
of comparison for other implementations.

Limitiations:  Assumes a 4-byte integer type and and pointers that are
32-bit aligned. Acts on a byte string of at most 2^36-16 bytes.
