I have a device which creates codes, and it has software to create passwords.
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?
That looks like a problem posted here by redrooster. I'm working on his, no solution yet.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.
