I haven't seen this mentioned on the list, so I thought I'd toss it
out. According to http://www.nstissc.gov/Assets/pdf/fact%20sheet.pdf ,
AES is acceptable for protecting Top Secret data. Here's the crucial
sentence:
The design and strength of all key lengths of the AES algorithm
(i.e., 128, 192 and 256) are sufficient to protect classified
information up to the SECRET level. TOP SECRET information will
require use of either the 192 or 256 key lengths.
