Ideally, that's how it should be done. I don't know if there is an RFC for 
CRC32 that you could simply reference (after checking that it conforms to 
your implementation of course).

Another approach, which I used in the past, is to use SHA-1 hashing 
instead (160 bits), and reference RFC 3174, which already carries an 
example implementation. If you need a free-to-use BSD-like license 
implementation of SHA-1, you can find one in my SHFtool test 
implementation (http://www.df.lth.se/~triad/krad/shftool/) which you are 
more than welcome to use if you like.

Hope this helps...

Yours,
