I've never played with one of them, but there are some "one way" encryption algorithms that can acomplish this job. They are called "one way" cause you cant restore an already encrypted item, you must encrypt a new one and see if they match. However in some circunstances it can be very easy to bypass this security system.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Jonah Sent: Jueves, 29 de Noviembre de 2001 01:32 p.m. To: Dynapi-Help Subject: [Dynapi-Help] theoretical javascript question Would it be possible, in theory, to securely validate a password client side? Obviously, simple string matching would not work because the client could view the source to find the correct password. But I have this vague notion (my upper level math skills are very rusty): Parsing the password up into characters perhaps, converting the chars to numbers, and then passing the numbers into the variables of a set of non-linear equations that must be solved simulataneously (in javascript, a set of functions that must return true simultaneously). I have no idea how you could generate the necessary difficult-to-solve set of equations given a particular password, but am curious to know if such an approach is viable even in theory. Anyone have any ideas?
