Simple Data Masking Algorithm

Question

Is there a simple algorithm where by I can convert a numeric value to alphanumeric and reliably convert it back to the same number?

For example, 12345 converts to 00A3DF and back to 12345.

Better write that example in code, is 12345 a string or an int? And does it have to be hexadecimal Alhpabumeric? Why not "12345" ? — Henk Holterman, Jun 22 '10 at 20:39
Are you talking about base conversion (i.e. decimal to base-36), or encryption? — drharris, Jun 22 '10 at 20:41
Except 12345 != 00A3DF in any conversion I know. It's definitely not hex, and doesn't seem like any obvious encryption like ROT13. — drharris, Jun 22 '10 at 20:51

I assume when you say alphanumeric you mean hexadecimal. This has already been answered:
