A system and method for database security provides multiple choices of security mechanisms for enabling access to a database through a database driver. A security mechanism that is compatible with a database is selected and the security mechanisms between an application and a database server are automatically determined using the selected security mechanism.

Automatic and adjustable system and method for synchronizing security mechanisms in database drivers with database servers

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.

Unified and persistent system and method for automatic configuration of encryption

A method is provided for developing a software module including support for multiple versions of an operating environment. The method includes determining a first set of references associated with a first version of an application operating environment. A second set of references associate with a second version of the computing environment is determined. A first class loader is associated with the first version of the computing environment. A second class loader is associated with the second version of the computing environment. The method also includes encapsulating the first set of references, the second set of references, the first class loader, and the second class loader in a software module, wherein the second set of references are obscured from the first class loader.
