I used the system checksum routine.

Not to encrypt the password and unencrypt it, but to encrypt it and store and compare only the encrypted version.

SYS(2007) will take a character string and return something else.

What it is you don't care so long as it's always the same for the same input!


Of course, this one-way process means you can never SEE the password but that's just like Novell, NT and just about all secure systems. All you can do is change the password to a new one.


Once the user has typed in their password, I use the function SYS(2007, txtPassword.value) to get the converted value which I compare against what's stored in the database.


It's secure, quick and I had to write one line of code!

OK, the SYS() function returns only 65000 unique values, so that with 6-character passwords the same numbers are returned about 1 in 1.5million tries.

But you cannot work backwards from the values in the table to the password you have to type to get them - so it's secure.
