To my knowledge there is not an Encrypt / Decrypt function in vb6 so I would suggest creating your own functions within the application. Make it something that is your own. One that I use is to use the CHR number of the letters in the password, perform a math function on the number. You could even alter the order of the numbers.

Example Password: MYPASS! Chr(77) = M (77 * 2) + 5 = 159 Store the first letter as 159 so the encrypted password looks like this: 1 Or in reverse 9 then to decrypt take each set of three numbers and reverse the process letter1 = CHR( (159 - 5)/2). The following pair of functions Encrypt & Decrypt will provide as simple solution. If you use with the expanded output you will get printable characters instead of raw binary data.

Here's my encryption class. I use several constants to define the encryption key because in my mind it's a little more secure from someone trying to decompile the code to find it. Cryptography isn't my thing so maybe I'm kidding myself. Anyway, I used this class in an ActiveX dll called from other programs to do encryption and the reverse in a separate dll for decryption. I did it this way so people who shouldn't be seeing encrypted data don't even have the dll to do the decrypting.

Change the key constants to what you want (5 long). I use a mix including unprintable characters and it has worked well for me so far. The is part of Windows® so you don't have to distribute.
