Im looking for a way to take a string and hash it to a unique number of a fixed size.  ie 6 digits.

I want to use this as key and then rehash the number 1 more time and produce another 6 digit number as the unlock code.  

the original string will be either variable in length or I can fix it to to a set number of characters but variable would be best.

the results of both hashes must be numeric and fixed length.

thanks for the help

A CRC check may be enough to do this for you http://www.freevbcode.com/ShowCode.Asp?ID=2755 is an example of this, you could easily convert the output to a long rather than a hex string and use this as your number, it will commonly be 10 digits but you could use perhaps the last 6 if required.
