A crypto signature decrypts to a document hash under the given user's public key, thus proving that the document was signed by the user's private key. Connelly 05:22, 21 Jul 2004 (UTC)
Matt,
The analogy of digital signatures to paper ones is, subtly, not very close. That's why I used the construction 'in a sense'. It wasn't quite weasel wording. The problem is that deiscussing the limited analogy is messy and not quite on point. I'm open to an alternative phrasing, in fact, I'd welcome one, but as it stands it's too easy to misconstrue the degree of analogy. Needs to be changed somehow.
- The analogy is close enough, IMO, to serve as an analogy; have a look at Schneier's Applied Crypto book (sec 2.6); he introduces digital signatures by listing the essential five properties of physical signatures that can be achieved electronically by digital signatures. — Matt 17:26, 18 Apr 2004 (UTC)
This is a real nuisance. Most of the legal beagles in the legislatures, at least on this side of the pond, have demonstrated some inability to get the distinction. And the legal beagles putting together position papers for the American Bar Association also failed to get it. There is an English soliciter/barrister (I'm almost colorblind on that one) named Nicholas Bohm who was (and may still be for all I know for I haven't been following this closely for a couple of years) one of the very few of these beagles who had the right scent. But he was advised closely by Brian Gladman (?) who did several reference algorithm implementations about the time of the AES break off. So there may have been reason why Bohm was better at this than most of the others.

- Matt, He does indeed and I remember his list. But the concern I have is based on work I did in support of a professional education seminar for lawyers here prompted by the passage of the Esignature Act of 2000. It's a swamp and I think we should be careful not to fail to convey a sense of caution here. That's what I was trying for with that phrasing. ww 18:29, 18 Apr 2004 (UTC)
