I am looking to decode the following X-JWT-Assertion using the axiom-api library ? I need to return the encoded header, body and Signature.Any pointers?

解决方案

I am using latest dependency from http://mvnrepository.com/artifact/org.apache.ws.commons.axiom/axiom-api.

Here is the sample code which I developed. Note: Signature code will not works, it's just a hint. In order to make signature working working you need keystore and read the alias and then decrypt it.

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import org.apache.axiom.util.base64.Base64Utils;

public class JWTAssertionReader {

    public static void main(String[] args) {
        String[] split_string = signedJWTToken.split("\\.");
        String base64EncodedHeader = split_string[0];
        String base64EncodedBody = split_string[1];
        String base64EncodedSignature = split_string[2];

        String decodedHeader = new String(Base64Utils.decode(base64EncodedHeader));
        System.out.println("Decoded Header :");
        System.out.println("===========================");
        System.out.println(decodedHeader);


        System.out.println("Decoded Body :");
        System.out.println("============================");
        String decodedBody = new String(Base64Utils.decode(base64EncodedBody));
        System.out.println(decodedBody);

        // I am not too sure you will not be getting Signature without the use of .keystore
        // Below code will not works, just will give hints / guidelines
        System.out.println("Decoded Signature :");
        System.out.println("==================");
        byte[] decodedSignature = Base64Utils.decode(base64EncodedSignature);
        Pattern pattern = Pattern.compile("^[^:]*:[^:]*:[^:]*:\"(.+)\"}$");
        Matcher matcher = pattern.matcher(decodedHeader);
        String base64EncodedCertThumb = null;
        if(matcher.find()){
            base64EncodedCertThumb = matcher.group(1);
        }
        byte[] decodedCertThumb = Base64Utils.decode(base64EncodedCertThumb);
        System.out.println(decodedCertThumb);
    }
}

The output below:
