Can't Unmarshal pgp elgamal encrypted message

[Bryan McGuire <bm...@westlakefinancial.com>]

Hi,
I've ran into a problem with the Camel-Crypto pgp DataFormat.  It works great with RSA keys, but with DSA/ElGamal keys it fails with the java.security.InvalidKeyException.  It does this because the signing DSA key is being used as the private key instead of the ElGamal encryption key.  For a test, you can make a simple route that just marshals and unmarshals using PGP format and DSA/ElGamal keys.
I opened https://issues.apache.org/jira/browse/CAMEL-5475 and have a patch included.

Below is a test case:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:TestGPG-context.xml"})
public class TestGPG {

    @Resource
    protected CamelContext camel;

    @Produce(uri = "direct:test.elgamal")
    protected ProducerTemplate myTemplate;

    @EndpointInject(uri = "mock:end")
    protected MockEndpoint endpoint;

    @Before
    public void initialize() throws Exception {
        camel.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {

                from("direct:test.elgamal")
                        .marshal().pgp("classpath:pubring.gpg","email@company.com")
                        .unmarshal().pgp("classpath:secring.gpg", "email@company.com", "password")
                        .to("mock:end");
            }
        });
    }

    @Test
    @DirtiesContext
    public void testTheirMocksAreValid() throws Exception {
        myTemplate.sendBody("file:src/data?fileName=plain_text.txt");
        endpoint.assertIsSatisfied();
    }
}
