Depending upon the nature of your data, I would be very concerned regarding the security of the data. Any reasonable cryptanalytic technique would be able to "crack" your cypher. You should look into encryption techniques like Blowfish, IDEA, Triple-DES etc... You should be able to find some free libraries if you google.
