java.lang.Objectorg.eclipse.emf.ecore.resource.impl.DESCipherImpl
public class DESCipherImpl
EMF implementation for the URIConverter.Cipher interface using
the DES encryption algorithm.
This shows how this class can be used:
Map options = new HashMap();
options.put(Resource.OPTION_CIPHER,
new DESCipherImpl("a very long key indeed"));
resource.save(options);
resource.load(options);
