I want to know if there is a way to create a random sequence of letters and numbers. In addition i want to encrypt the result or convert it to a number, so that i can perform a calculation on it and return a unique number that will be used as an unlock code.
In essence i want :
RH6766759NJCQ900W this must then be converted to a number i.e: 685126487562344785 which i can then do a calculation on to create another number.
this is to be used as an anti copy system to my DB.
