Hi kanykey;

That looks like a problem posted here by redrooster. I'm working on his, no solution yet.

I have a device which creates codes, and it has software to create passwords.
for example:
1.  if 003472BL-2345 then the password is 2DD6
2.  if 003473BL-2345 then the password is EC57
3.  if 000000XX-2345 then--F9B5
4. if 003470BL-2222 then A8CF

I tried to decode its code many times, but I could not resovle it.
What kind of coding system is it using?

best regards,
