It's late and I'm tired, but this article lacks information on (a) the input/output transformation stage, and (b) the subkey generator. →Raul654 03:19, Mar 21, 2004 (UTC)

True, but they aren't very interesting... Matt 03:36, 21 Mar 2004 (UTC)

I'll add them to the to-do list anyway. — Matt 23:24, 27 Nov 2004 (UTC)

I have added an image showing the transformation round. danielap48 02:04, 19 Oct 2006 (UTC)

Image format

Erk, it looks very ugly with a grey border around it; is there any reason you wanted it 200px and not 250px?

— Matt 20:47, 18 Apr 2004 (UTC)

The manual of style says not to use HTML-formatted pictures like that - it's depricated since we got the wiki image markup language. If you don't want the grey border, then simply remove the "thumbnail" switch. However, doing that removes the caption. Tell you what - read Wikipedia:Picture tutorial (I wrote it :D) and tell me what format you would prefer. →Raul654 20:51, Apr 18, 2004 (UTC)

Is there no way to have no border AND a caption? — Matt 20:53, 18 Apr 2004 (UTC)

Only with html tables, and we generally discourage that. If you do it with no thumbnailing (no grey border), then the caption shows up if you hover the mouse over the picture. →Raul654 20:55, Apr 18, 2004 (UTC)

Hmm, that's unfortunate; I've flicked between the versions, and it does look quite a bit uglier (IMO) with the thumbnail box, but really could do with the caption rather than be a bare image. Could we just leave it as is for now? I'm all in favour of removing nasty HTML stuff from wikitext, but it might still be best for treating floating white-background diagram-type things ... — Matt 21:11, 18 Apr 2004 (UTC)

It does look a lot nicer in the new skin! — Matt 11:03, 30 May 2004 (UTC)[reply]

Diagram

Can someone please edit the image to make it clear when paths cross over, perhaps with the little bridges seen on wiring diagrams? Pimantony 19:41, 27 March 2006 (UTC)[reply]

Incorrect Key Schedule description

The key schedule is incorrectly described. The 25 bit left rotate is not applied to the 128 bit key until after the full 128 bits are used in the key. This happens in the middle of the second round (96 bits are used for the first round, the remaining 32 bits are used in the second round.) The rotate left operation is only performed a total of 6 times in the key schedule. —Preceding unsigned comment added by 216.83.134.34 (talk) 03:35, 21 June 2008 (UTC)[reply]

External Link

The IDEA applet link does not appear too useful, not in English and I saw no way to run a simulation.--Billymac00 (talk) 19:24, 4 January 2009 (UTC)[reply]
