Getting around installing MHASH for

I'm trying to set up a simple form to be posted to so the customer can charge their card. I keep on getting the error that I need the MHASH function.
The php server version I'm on is 4.3.*. I don't have access to the actual server so I can not install anything or upgrade the system.
Is there any other way around this?

You really shouldn't need the MHASH library at all.  

First, you don't need to hash anything to send a transaction to  You will need to calculate an MD5 hash of some of the return data in order to verify the security of the communication, but that does not really impact the transaction as much as your application's perception of it.

That brings us to MD5:

Chances are, you're trying to use MHASH to generate an MD5 hash of your data.  If that's the case, you can use the internal md5() function instead.  No additional libraries are needed.

If you're not aiming for MD5 functionality, tell us what algorithms you need to include, and we can tell you where else they might be available.
Download SquirrelMail and look for the code handling DIGEST authentication. DigAuth involves calculating MD5 hashes and as far as I remember there was a pure PHP implementation of mhash there. If not, try googling "pure php mhash". Alternatively, see if they have Perl/Python packages installed that calculate mhash.
