Add Signature in a SOAP request in Apache JMeter - soap

Question

I need to add signature using X509 certificate in SOAP request in Apache JMeter.
I already have .p12 with me.
Please help how can I achieve it in Apache JMeter.
I know how to do it in SOAPUI but not finding any way in JMeter.

Answer 1

don't know wheter you need this answer still but I ran into the same problem and got it fixed after a couple of days of work and I suppose others might find this usefull as well...
I based my answer upon the answer by Dmitri T; the blog post on blazemeter, this bugreport + some custom hacking.
Let's assume you need to sign this request:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="http://custom.namespace.com/service-v1.0-rc2">
<soap:Header>
<wsa:MessageID xmlns:wsa="http://www.w3.org/2004/12/addressing">a2749a0f-555-9135-367ed901d244</wsa:MessageID>
</soap:Header>
<soap:Body>
<ser:request>
<ser:person>
<ser:id>11552</ser:id>
<ser:number>81067776992</ser:number>
</ser:person>
</ser:request>
</soap:Body>
</soap:Envelope>
You've followed the guide on blazemeter until the part with the custom java code to sign the request.
In stead of using that code do the following:
Copy paste the following code into JMeter(3.0):
import com.example.wss.SOAPSecurity;
import org.apache.jmeter.services.FileServer;
// get SOAP message from parent sampler body
String soapData = sampler.getArguments().getArgument(0).getValue();
String baseDir = FileServer.getFileServer().getBaseDir();
String pathToKeystore = baseDir + File.separator + "keystore_files" + File.separator + "your.jks";
String keystorePassword = "yourPassword";
int timeToLive = 5000;
String signingAlias = "yourAlias";
String encryptAlias = "yourEncryptingAlias";
String secureSoap = "";
try {
secureSoap = SOAPSecurity.secureSoapMessageFromString(soapData, pathToKeystore, keystorePassword, null, null, timeToLive, signingAlias, yourEncryptingAlias);
}
catch (Exception ex){
log.warn("Error in script", ex);
throw ex;
}
// replace parent sampler body with secured SOAP message
sampler.getArguments().getArgument(0).setValue(secureSoap);
vars.put("SoapDataRaw", secureSoap);
Use groovy as interpreter.
This is the java class file adapted for my use case:

Put the code in a com\example\wss\SOAPSecurity.java file
Put wss4j-1.6.18.jar in the same dir.
http://archive.apache.org/dist/ws/wss4j/1.6.18/
I compiled/build/deployed it with this .sh script (you can use cygwin for that):
/cygdrive/c/Program\ Files\ \(x86\)/Java/jdk1.8.0_73/bin/javac.exe -cp wss4j-1.6.18.jar com/example/wss/SOAPSecurity.java
cp SOAPSecurity.jar SOAPSecurity.jar.bak$1
zip -r test.zip com/
mv test.zip SOAPSecurity.jar
cp SOAPSecurity.jar /cygdrive/c/Program\ Files\ \(x86\)/apache-jmeter-3.0/lib/
Run JMeter 3.0 with the .bat file
-> the SOAPSecurity.jar should be in the apache-jmeter-3.0/lib/ folder
-> I have also these configuration in JMeter's system.properties file:
-Djavax.net.ssl.keyStore=C:/path/to/client.jks
-Djavax.net.ssl.keyStorePassword=verySecret
-> and added a keystore configuration element to the soap request in JMeter
So, this is about it, feel free to give it a spin and let me know whether it worked for you, if not I might provide some help, if you'd like to debug yourself an excelent way to do so is by adapting/placing System.out.println's in the custom class, it gives very usefull information about what's going on and can be quite a life saver,
Keep having fun!!!

Answer 2

You need to do some scripting in order to encrypt the message via the JSR223 PreProcessor. The idea is to get current sampler body, encrypt it and replace on-the-fly.
Add JSR223 PreProcessor as a child of the request
Use the following code as a reference:

//create basic structure of signature
javax.xml.parsers.DocumentBuilderFactory dbf =
javax.xml.parsers.DocumentBuilderFactory.newInstance();

DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
String request = sampler.getXmlData();
ByteArrayInputStream in = new ByteArrayInputStream(request.getBytes());
Document doc = dBuilder.parse(in);
in.close();

XMLSignature sig =

X509Certificate cert =
(X509Certificate) ks.getCertificate(certificateAlias);
sig.addKeyInfo(cert);
sig.addKeyInfo(cert.getPublicKey());
sig.sign(privateKey);
}
//write signature to file
FileOutputStream f = new FileOutputStream(signatureFile);
XMLUtils.outputDOMc14nWithComments(doc, f);
f.close();
//set sampler's XML data from file
String request = FileUtils.readFileToString(signatureFile);

You will need to replace keystore and encryption related bits as per your configuration and service definition
