package org.jasypt.web.pbeconfig;
/**
*
* Interface which must be implemented by the user-defined classes which
* create and initialize webapp PBE encryptors for being configured through
* the web pbe configuration servlet.
*
*
* This interface only has one method, {@link #initializeWebPBEConfigs()},
* which the implementation class should use for creating encryptors and
* setting {@link WebPBEConfig} objects to them, like:
*
*
* package myapp;
* ...
* public class MyWebPBEInitializer implements WebPBEInitializer {
*
* public void initializeWebPBEConfigs() {
*
* StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
* encryptor.setAlgorithm("PBEWithMD5AndDES");
*
* WebPBEConfig webConfig = new WebPBEConfig();
* webConfig.setValidationWord("jasypt");
* webConfig.setName("Main Password");
*
* encryptor.setConfig(webConfig);
*
* // Get some user-defined singleton or similar, and register
* // the encryptor with it so that it can be accessed from the
* // rest of the application.
*
* }
*
* }
*
*
* All WebPBEConfig objects get internally registered at
* instantiation time, and once assigned to an encryptor they will appear
* in the web form for password setting.
*
*
* Important: If the web application uses Spring Framework, WebPBEConfig
* objects are declared as beans in the Spring context and this Spring context
* is initialized at application deploy time
* (with Spring's ContextLoaderListener), it will NOT be necessary
* to create
* any classes implementing this WebPBEInitializer interface.
* The use {@link WebPBEInitializationContextListener} will also become
* unnecessary.
