I'm looking for a free method to apply a one-way encryption

[val%2] is a one-way hash, but I suppose you want to map onto a bit larger
space.
I should have been a bit more specific... I want to take my 64 bit value and
apply a process to it that will yield a unique value that cannot be easily
reversed back to the original value.
I will have a database with 13000 unique 64-bit identifiers, but those
identifiers have been deemed mildly sensitive by a higher power. Now, I
would rather have a database with 13000 non-sensitive unique identifiers,
each of which can be obtained by applying a process to the original
sensitive identifier. Thus if my server is compromised (or the server of a
third party that will host the same data) I won't have to worry about the
revelation of these identifiers (not SS numbers BTW).
I found several links in the ASP FAQ, but nothing free that meets this
requirement. I might just have to pay or move on to Linux, but I was
checking first. :)
