A few days ago Dimitri (aka Dimava) sent me an exe file (attached in a zip) where you enter in a 5 letter keyword and it would output a 5 letter password. Now the problem is that the program was made in 1992 and the src is no longer around, yet dimitri needs to know the algorithm for creating the password from the keyword.
I have attached the program and i have also some notes from me playing around with it:
If you look at the above list you can see that the letter 4th along in the keyword some how by changing that it relates to the first letter of the password so like A seems to match to U and B to T. I have a few more notes too)
Can anyone help to attempt to crack the keyword to password algorithm ?

I'm willing to help
The 3rd letter becomes the first one. The letters varie with their position - it seems to me that their Ascii value is increased by some ammount.

Since its encryption its likly to use some sort of random number or some **** like that which is quite hard to crack. Why not use a program like Windasm32 and look at the assembly in the program that encrypts/decrypts it then from that u will have a better idea of how it works or make a crack for it

MAN!!!
Do you expect to easily write a decrypting program for something that has been encrypted with +80kbs of code?!

Well, you've got the source, so don't you have the algorithm? Shouldn't be too hard to convert VB (he says thanking his lucky stars that he's not the poor bastard whose got to do said conversion)
The "C" code is just glorified assembler. The best you could do woyuld be to convery sub by sub, but it's messy as all hell, with calls left right and centre.
Well i (coz i know C++ unlike dimava) had a look at it but it looks seriously messed and it would not compile on my pc due to like 400errors and 200warnings. So.....
