Do we have any methods to encrypt the payload using the certificate which is coming in the JSON payload or Header etc.

1. XSLT via dp extension function?
2.Gateway Scripts ?.

is this possible ?.

i have looked at "node-forge". I couldn't contemplate how we can use this kind of scripts in datapower

"Forge uses a CommonJS module structure with a build process for browser bundles."

https://www.ibm.com/support/knowledgecenter/SS9H2Y_7.7.0/com.ibm.dp.doc/gatewayscript_model.html

Gateway script includes ECMAScript, CommonJS, and DataPower-specific GatewayScript APIs.

You should be able to use Forge with GatewayScript because of CommonJS.

Hi Hermann

I have upload the forge files(https://github.com/digitalbazaar/forge/tree/master/lib) into dp and it seems some of the codes meant for browser . Any idea how to address this errors?.

****My js code as below
var service = require('service-metadata');
var pki = require('pki');
service.mpgw.skipBackside = true;
var pem = '#######';
var cert = pki.certificateFromPem(pem);
console.log(cert.validity.notAfter);
****
Note : Removed my cert details from var and placed as ###

Below are the errors :
GatewayScript processing Error 'ReferenceError: window is not defined In file 'local:///util.js' line:123, stack:ReferenceError: window is not defined at local:///util.js:123:40 at Object.<anonymous> (local:///util.js:124:3) at ModuleContext.require (gatewayscript:///datapower.js:406:33) at Object.<anonymous> (local:///asn1.js:137:1) at ModuleContext.require (gatewayscript:///datapower.js:406:33) at Object.<anonymous> (local:///pki.js:10:1) at ModuleContext.require (gatewayscript:///datapower.js:406:33) at Object.<anonymous> (local:///commonnameverify.js:11:11) at Script.execute (gatewayscript:///datapower.js:155:24) at Object.<anonymous> (gatewayscript:///datapower.js:582:55)'

Hi,
you have to replace code based on undefined window.
Only function using window in util.js is "util.getQueryVariables":

https://github.com/digitalbazaar/forge/blob/master/lib/util.js#L2340

Just reimplement that function making use of GatewayScript querystring module:

https://www.ibm.com/support/knowledgecenter/SS9H2Y_7.7.0/com.ibm.dp.doc/querystring_js.html

Do you get an error when using it?
