Abstract
An apparatus for integrated dynamic encryption and/or decryption for use in an application includes a policy filter, a policy filter module coupled to the policy filter, a service module coupled to the policy filter, and a cryptographic module, where the method and apparatus retrieve the cryptographic module and configure the policy filter in accordance with the cryptographic module. The policy filter module performs a plurality of verification upon the cryptographic module. The service module is configured to generate a plurality of cipher suites and the policy filter is configured to filter the plurality of cipher suites in accordance with predetermined policy filter parameters to generate a plurality of filtered cipher suites.
