Hello everyone, I have a very simple question - how to(using what) calculate a hash of my e-mail address?

LiveJournal does a hex-encoded SHA-1 hash of "mailto:email@address.com", substituting, of course, your email address.

In perl, you could do this:

use Digest::SHA1;
Digest::SHA1::sha1_hex('mailto:youremail@address.com');

Which of course requires that you've got Digest::SHA1 installed. Other programming languages will have their own ways of pulling that off.

Thanks!

Do you mean programatically, or just to have something to stick in your FOAF file? If the latter, the following would work on most unixy systems:

echo -n 'foo@bar.com' | md5sum

or

echo -n 'foo@bar.com' | sha1sum

depending on the algo you want to use.

For the foaf file, it's actually "mailto:foo@bar.com", because it's designed to be a resource.

Good point :)

If you are just trying to get the hash of your address, there are several tools at http://xml.mfd-consult.dk/foaf/ one of which will sh1ify your address.

If you are looking for the spec, it is located at http://xmlns.com/foaf/0.1/

this is actually what I wanted - as a lazy programmer. lazy programmers prefer tools rather than coding%))))
