PGP Encryption with Apache Camel

问题


I am trying to encrypt and decrypt a file using PGP Encryption/Decryption methodology with Apache Camel.

Further I have installed Kleopatra to generate the private and public keys. Using Kleopatra i have generated my keys successfully. The secret key and public keys are in ".asc" extension.

Below is the piece of code i am using to encrypt the file

import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;

public class PGPENC {
    public static void main(String[] args) throws Exception {
        CamelContext camelContext = new DefaultCamelContext();

        camelContext.addRoutes(new RouteBuilder() {
            public void configure() throws Exception {

                String publicKeyFileName = "file:C:\\Users\\karthick\\Desktop\\PGP\\PGP\\Public_Key.asc";
                String keyUserid = "Karthick Sambanghi <karthick88it@gmail.com>";

                from("file:C:\\Users\\ITSS\\karthick\\PGP\\PGP\\IN?noop=true;delete=true").marshal()
                        .pgp(publicKeyFileName, keyUserid).to("file:C:\\Users\\ITSS\\Desktop\\PGP\\PGP\\OUT");

            }
        });

        camelContext.start();

        Thread.sleep(5000);
        camelContext.stop();
    }
}

Here the program executed successfully without any errors but the file is not being encrypted in OUT folder. Is there anyway to check the "camelContext" return statement whether it is success or failure ?

Below are the libraries used currently for executing the program

bcpg-jdk15on-1.52
bcprov-ext-jdk15on-1.57
camel-context-2.22.1
camel-core-2.22.1
camel-crypto-2.19.1
slf4j-api-1.7.25
slf4j-nop-1.7.25

you can enable camel logging in the console using by adding in your programm org.apache.log4j.BasicConfigurator.configure().

Using that you could verify if the route started and consumed the file. so Executing your programm with adding some logs :

 CamelContext camelContext = new DefaultCamelContext();
    BasicConfigurator.configure();
    camelContext.addRoutes(new RouteBuilder() {

      public void configure() throws Exception {

        String publicKeyFileName = "file:C:\\LocalData\\Keys\\pgp_public.asc";
        String keyUserid = " ";

        from("file:C:\\Test\\Test\\IN")
            .log("file received")
            .marshal().pgp(publicKeyFileName, keyUserid)
        .to("file:C\\Test\\Test\\OUT");

      }
    });
    camelContext.start();
    Thread.sleep(30000);
    camelContext.stop();
  } 

I can notice that the route is starting, consuming files from the in folder and fails then with the exception :

Caused by: java.lang.NoSuchMethodError: org.bouncycastle.openpgp.PGPPublicKeyRingCollection.<init>(Ljava/io/InputStream;)V
    at org.apache.camel.converter.crypto.PGPDataFormatUtil.findPublicKey(PGPDataFormatUtil.java:64)
    at org.apache.camel.converter.crypto.PGPDataFormatUtil.findPublicKey(PGPDataFormatUtil.java:54)
    at org.apache.camel.converter.crypto.PGPDataFormat.marshal(PGPDataFormat.java:64)
    at org.apache.camel.processor.MarshalProcessor.process(MarshalProcessor.java:59)
    at org.apache.camel.util.AsyncProcessorConverterHelper$ProcessorToAsyncProcessorBridge.process(AsyncProcessorConverterHelper.java:61)

This is a bug in Camel documentation, please find here details: https://jira.apache.org/jira/browse/CAMEL-12574
