[edit] BATON key size

The article currently reads:

BATON has a 128-bit block size and a 160-bit key. 160 bits of the key are checksum material; they doesn't affect the security of the algorithm itself but rather prevent unauthorized keys from being loaded if a BATON device ends up in the hands of an adversary.

This is certainly wrong. Probably what is meant is "16 of the bits..." but I have no information to verify this claim. Andrew 21:51, Nov 13, 2004 (UTC)

Off the top of my head, I half-remember reading that it was 320 bits, of which 160 bits were some sort of checksum, leaving 160 bits as the size of the key space. But, as we (hopefully) aren't writing articles based on half-rememberances, I'll try and dig up an actual source soon! — Matt 23:10, 14 Nov 2004 (UTC)

[edit] Used broadly?

Since late 2004, the lead sentence has claimed that this cipher is "used broadly throughout the United States government to secure all types of classified information". That may have been true in 2004, but is it still so today? One would expect it to be superseded by AES, at least for civilian applications that don't rely on algorithmic obscurity. –Henning Makholm 15:45, 26 May 2007 (UTC)

Yeah, or at least, I think it would be good to get some reliable sources for this sort of stuff. — Matt Crypto 16:45, 26 May 2007 (UTC)
