the reason for this, is that it protects you from the sysadmin himself. even he can't scan your password (unless he runs a mega-loop hashing and comparing all possible strings against the stored one) which can take hours, days or weeks to break. Which is why you should use long passwords on secure information (and change it from time to time).
I am not sure how rebol hashes the password, but some algorythms make it possible for more than one password string to return the same hashed value. That is one reason it is not reversible. I'm not the expert, but these are little tidbits I've collected in my time ;-) -MAx --- "You can either be part of the problem or part of the solution, but in the end, being part of the problem is much more fun." > -----Original Message----- > From: Maarten Koopmans [mailto:[EMAIL PROTECTED] > Sent: Tuesday, October 21, 2003 3:42 PM > To: [EMAIL PROTECTED] > Subject: [REBOL] Re: reading back checksum/secure > > > > You can't.
