Many databases have column (or field) level encryption - a special type of encryption to protect sensitive data like credit card numbers or social security numbers. MySQL has transparent table level encryption but does not have more granular / application centric column level encyption. In this talk I will demonstrate how one can implement a column level encryption which combines an application key and a server key. This design will also require no to minimal changes to the application and provide a higher level of protection for sensitive data.
