That's a great suggestion. I will try this and report back. It's also been suggested to me that I should have base64_encoded the encryptions before storing them in MySQL, so I'll try this option at the same time.

For a decent test, you'll want to test it against a lot of numbers, store each one in plain format in the DB (use the same character encoding as you already have to see if that's part of the issue) alongside the encrypted version, then retrieve the encrypted value and test it against the original. It may take only a few dozen numbers to show the problem, it may take a thousand, but just let it run until it finds a problem.
