* Encoder

* Validator

* Authenticator

* AccessController

These implementations can be wrappers around existing tools, the primary purpose of this exercise is to evaluate the provided APIs to ensure that the interfaces are usable to developers.

ESAPI 3.0.0 will provide an additional component (ESTAPI - thanks to Dinis Cruz for the name) which will allow implementors to run tests against their implementations of a given control to ensure that it is in fact implemented securely. For GSoC I would like to focus this effort on a set of concrete tests for the Validator and Encoder interfaces as well as a fuzz test against both of those interfaces as well. Propose a design for how the tests will function and be run, then create a new repository (and link back to ESAPI/esapi-java) with your implementation.

One of the things that ESAPI aimed to provide was a means to enforce a centrally managed enterprise security policy in a provable way. Propose an idea and implement a proof-of-concept using the following design concepts:

* The enterprise security policy should be published in a parseable format - it can be XML, JSON, or any other schema based language.

* The enterprise security policy should allow downstream configuration overrides, but provide a audit event indicating a policy item has been overridden by a child policy

* The enterprise security policy should have a simple interface for configuration of the policy parameters, and should provide sane defaults for all controls

1. *Design Verification* - Interfaces should be fairly locked down at the first release. The interfaces should be tested thoroughly by implementing a baseline set of components *and* testing inclusion of those components in real-world applications.

1. *Solid interface documentation* - All interfaces should be fully documented in Javadoc

1. *Component Community Library* - An Apple Store'esque implementation of a community containing reviewed and approved controls that implementors can pull into their projects

1. *Discovery* - The ESAPI should provide a discovery module that discovers, registers, and configures controls (according to the enterprise security policy) - this can function similar to OSGi

1. *ESTAPI* - A full suite of tests that can provide assurance that controls are implemented correctly. ESTAPI testing will be a pre-requisite to inclusion in the Component Community Library.
