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

DES key length
editArticle 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. — 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#Key schedule, which explains the dropping of bits, and the meaning of PC-1/2 etc, in the text. — Matt Crypto 15:44, 26 January 2007 (UTC)

Worldwide?
editWhat'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.
