While working on the NTS test code I have reached a point where I
know that I am misunderstanding *something*, but do now know what.<br>
<br>
According to the RFC the AEEF "ciphertext" field looks like it is a
generally usable data blob for extension data. Variable size, no
specific data, etc.<br>
<br>
According to the code the AEEF "CMAC" field which is in the same
spot looks like a fixed length data blob with a very specific
meaning.<br>
<br>
These do not match up, and I do not know what I am missing.<br>
