A system and method for database security provides, a database security method that receives an encryption property from an application and receives information relating to a database server. The method then requests security access to a database server using the strongest encryption algorithm server may support. If this request gets turned down, then the method determines the strongest encryption algorithm the server actually supports using the information the database server sent back and calculates the encryption keys. The method then caches the encryption algorithm along with the encryption keys in a persistent storage. For subsequent connections, the method checks the persistent storage first and retrieves the encryption algorithm and encryption keys from the persistent storage if the cache values are available, and sends the cached value to database server. By doing this, the database driver doesn't need to synchronize the encryption algorithm with server and calculate the encryption keys again. |
