Hash! - Good idea! --On Mittwoch, 16. Jänner 2002 16:25 +0100 Markus Schaber <markus.schaber@student.uni-ulm.de> wrote:
mails with exactly the same values for that would be identical (result will be the same hash-value)... and there's no need to store them.
No, not really. A hash is just very likely to be different for different data, but it is not guaranteed.
That's right, but when you use a cryptographic one-way-hash like MD5 or SHA-1 it's not very likely. Besides that it would mean that there cannot be more than one object with exactly the same content. Juergen
