JDOM

Enigma operates on JDOM objects – Documents and Elements. The use case for Enigma is an XML-based information system. Individual Elements can be locked and/or signed, then unlocked and/or verified. This means that the arguments to the most commonly used Enigma methods must be JDOM Element objects. Enigma isn’t a complete implementation of XML-ENC or XML-SIG, but it produces XML documents containing conforming elements in those namespaces, so fully-conforming implementations should be able to decrypt and/or verify documents produced by Enigma.
