Talk:Key schedule

Category
Doesn't this article belong in the Cryptographic Algorithms category, not the Key Management category?

 * Good point. I've changed it.--agr 09:37, 20 December 2006 (UTC)

DES key length
Article text states 56-bit keys (which I believe is correct) whereas the diagram states that there are 64 bits in the key (which I believe is wrong). They should agree with each other, and (this would be helpful) both be right... JulesH 13:16, 26 January 2007 (UTC)
 * You are right, the image is incorrect. I commented it out until someone fixes it. -- intgr 13:42, 26 January 2007 (UTC)
 * I believe the diagram is correct. The cipher is specified to accept a 64-bit key, but 8 of those bits are simply ignored by PC1, so it has an effective key size of only 56 bits. &mdash; Matt Crypto 14:46, 26 January 2007 (UTC)
 * Oh, okay; perhaps the diagram could be changed to reflect that more clearly? -- intgr 14:51, 26 January 2007 (UTC)
 * Could do, or perhaps just a note in the caption would suffice if we think it's confusing. The diagram was originally  intended to illustrate Data Encryption Standard, which explains the dropping of bits, and the meaning of PC-1/2 etc, in the text. &mdash; Matt Crypto  15:44, 26 January 2007 (UTC)

Worldwide?
What's the "worldwide" tag for? I don't think key schedules are a nation- or culture-dependent subject. The article could be expanded, but I think it's fairly universal. Ntsimp (talk) 14:35, 13 July 2008 (UTC)


 * Well, that tag was added by the same anon user that added the "It is requested that a photograph or photographs be included in this article to improve its quality" tag to lots of crypto algorithm talk pages like this one. I think we can simply revert his tagging since he seems to not know what he is doing.
