How to access EncodeDecodeResult from jython zap

Is there a way to access EncodeDecodeResult from a python script? I cannot import it. When I create an Encode/Decode script and return a simple string I get the following error.

java.lang.ClassCastException: class java.lang.String cannot be cast to class org.zaproxy.addon.encoder.processors.EncodeDecodeResult (java.lang.String is in module java.base of loader 'bootstrap'; org.zaproxy.addon.encoder.processors.EncodeDecodeResult is in unnamed module of loader org.zaproxy.zap.control.AddOnClassLoader @440b6dca)

When I try to import the module like this

import org.zaproxy.addon.encoder.processors.EncodeDecodeResult

I get

Traceback (most recent call last):
  File "<script>", line 483, in process
ImportError: No module named addon

The first error seems to hint by saying that org.zaproxy.addon.encoder.processors.EncodeDecodeResult is in unnamed module of loader org.zaproxy.zap.control.AddOnClassLoader, but I don't know how to use that.

An ugly hack I found is to raise an exception with the result string which will show the result on the encoder/decoder view. That would have been somewhat acceptable if it didn't disable the module after that.

Solution

  • Here's a basic example of a Python (Jython) script for Zap's Encode/Decode/Hash functionality. This example simply appends the string TEST to the end of whatever is input.

    from org.zaproxy.addon.encoder.processors import EncodeDecodeResult

def process(value):
    return EncodeDecodeResult(value+"TEST");

    I'll work on getting a template added to the various scripting add-ons.
