I have about 1000 6 digit numbers that will always be unique in my data. They represent an employees ID. Its part of a key index
I dont want others to see this number as is. What would be a good algorithm I could use/create using vb to change the value to something else that people wouldnt recognize and not be able to figure out what the real number is.
It must still be unique among the other numbers, and I would need to ability to use code to reverse the algorithm back to the original number. So I think that leaves out random number generation
I welcome your thoughts
