It's exciting to get that reverse shell or execute a payload, but sometimes these things don't work as expected when there are certain defenses in play. For a Python graph database. In some cases, the secondary intention of data serialization is to minimize the data's size which then reduces disk space or bandwidth requirements. After we create a List of Bytes, then we call the function that saves this List in Format JSON. Get notifications on updates for this project. Usage is shown in the screenshot below. spyderproject. object_hook is an optional function that will be called with the result of any object literal decoded (a dict).
