/**
*
* This class acts as a stateless service for encryption, decryption and
* digest operations, letting its clients configure all the jasypt environment
* (algorithms, passwords, providers, initialization vectors...) from Strings in a single call, be it
* using direct values, environment variables or java vm properties.
*
*
* It is meant to service the CLI interfaces, but it can also be used for other
* purposes. For instance, by subclassing or wrapping it with a JAX-WS web
* service class, developers can easily create an encryption web service.
