Hello,
Given a number, how can I create a unique key from this number. This key should never be repeated when given different number (So its more math algorithms)
More explanation:
Here is exactly what my program does, I generate a code depending on the system time. For example if today is 07/05/08 16:05:55
The generated code is 0508160555 <---last 10 digit only
I need to use this number to generate a unique key for licensing, but the algorithm that I'm using is poor, rarely it generates an existing key from different number.
I don't want to use MD5 because I still need to be able to decode, means get the code back using the key.
Any help will be greate..Thank you!
