the pickle module 's interfaces are incredibly simple to use. For example, to pickle an object into a serialized string, we can either make a pickler and call its methods or use convenience functions in the module

To unpickle external objects, the unpickler must have a custom persistent_load() method that takes a persistent ID object and returns the referenced object. Here is a comprehensive example presenting how persistent ID can be used to pickle external objects by reference. # Simple example presenting...
If the connection is unencrypted, the pickle received could have also been modified on the wire. Another attack scenario is when an attacker can access and modify the stored pickle files from caches, file systems, or databases. The following example code demonstrates a simple client server ...
