+<h1>AES key wrap</h1>
+
+<p>A preliminary implementation of AES Key Wrap, RFC 5649 flavor, using
+Cryptlib to supply the AES ECB transformations.</p>
+
+<p>aes_keywrap.py contains two different Python implementations:</p>
+
+<ol>
+<li><p>An implementation using Python longs as 64-bit integers; and</p></li>
+<li><p>An implementation using Python arrays.</p></li>
+</ol>
+
+<p>The first of these is the easiest to understand, as it can just do
+(long) integer arithmetic and follow the specification very closely.
+The second is closer to what one would do to implement this in an
+assembly language like C.</p>
+
+<p>aes_keywrap.[ch] is a C implementation.  The API for this is not yet
+set in stone.</p>
+
+<p>All three implementations include test vectors.</p>
+
+<p>The two implementations based on byte arrays use shift and mask
+operations to handle the two numerical values ("m" and "t") which
+require byte swapping on little endian hardware; this is not the most
+efficient implementation possible, but it's portable, and will almost
+certainly be lost in the noise under the AES operations.</p>
