/**
*
* Implementation for {@link PBEConfig} which can be used from the
* Web PBE Config infrastructure (Filter + Servlet) to set the
* password for an encryptor from the web at initialization time.
*
*
* For an encryptor to be assigned a password from the web, it only has
* to be assigned a WebPBEConfig object, which must be initialized with
* both a unique name an a validation word. The name will identify
* the config object (and thus the encryptor) and the validation word will
* make sure that only an authorized person (for example, the application
* deployer) sets the passwords.
*
*
* As this class extends {@link SimplePBEConfig}, parameter values
* can be also set with the usual setX methods.
*
*
* For any of the configuration parameters, if its setX
* method is not called, a null value will be returned by the
* corresponding getX method.
*
*
* @since 1.3
