Table for data
Is there an easy way to put data, like in this article, into a table? --David W Gillette 14:55, 21 July 2007 (CDT)

Is there a mathematician in the house?
I've just added an article birthday attack on a cryptographic application of the birthday paradox, with a link from here.
Part of the text there is: "In general, for a cryptographic primitive of size n bits, the attack cost is 2n/2." That's a well-known rule among crypto folk; it's in the standard references and is used in government standards, see the last paragraph of birthday attack. However, I've never seen a proof and do not know if it is a theorem or just a handy approximation. Can anyone clarify this? Sandy Harris 13:32, 1 November 2008 (UTC)
