pypickle

pypickle is a user-friendly Python library for saving and loading data using the pickle format. Unlike the standard pickle module, pypickle puts safety first—offering built-in validation, extension checks, and protection against common exploits. Whether you're persisting models, storing session data, or sharing files, pypickle makes serialization easy and more secure. Ideal for developers who care about both convenience and peace of mind. ⭐️ Star it if you like it ⭐️

Key Features

Feature	Description
Load	Load your pickle files.
Save	Save your files into pickle format.
is_critical_path	Check whether filepath is critical.
get_critical_paths	Get critical paths.
get_risk_modules	Get risk modules.
get_allowed_paths	Get allowed paths.

---

For security reasons, pickle files are validated by checking the inner modules before loading. Twenty modules are classified as high-risk (see here) and can not be loaded without validation.

Module Type	Allowed?	How to Change Behavior
Unknown	✅	Allowed unless in high-risk list
Custom safe	✅	If included in validate param
Risky (os, etc.)	❌	Must be explicitly added via validate=['nt'] or validate=False
