Prerequisites

PyCript provides the flexibility to implement custom encryption and decryption algorithms using any programming language. To utilize PyCript, one must have a compiled binary of the custom encryption and decryption code with Windows PE or Mach-O etc or the language to run the script or executable like Go, Python, Nodejs etc.

Burp Suite configured with Jython to install the Python extension

Note

PyCript v0.4 allow any language as an encryption-decryption script. You can use a script like Python JavaScript, and Java as older versions as well as other languages like C, Go, C++ or any language even Bash or Powershell scripts as well, With version 0.4 there is no restriction in the language.

Note

PyCript v0.4 change the working of the extension, the older script of encrpytion and decryption will not work with version 0.4

Note

If you choose to use the Java programming language with PyCript, you will require a JAR file to be provided. Please ensure that you include the JAR file, and not the compiled class file or Java source code, when using PyCript.

Note

When opting to utilize JavaScript with PyCript, it's essential to ensure that all necessary libraries are present in the folder where encryption and decryption files are stored. This is particularly important as many Node.js libraries require the presence of related dependencies in the same directory as node_modules.
