Mastering and Understanding Linux Passwords with crypt and passlib in Python

In this video, we dive into the evolution of password hashing in Python, starting with the deprecated crypt module and transitioning to the more secure and modern passlib library. You'll learn about how password hashing works, the importance of using strong hashing algorithms, and how to customize the number of hashing rounds to increase security. We'll cover: What password hashing is and why it’s important for securing user data. The limitations of the crypt module and why it’s being deprecated in Python 3.13. How to use passlib, a powerful library that supports modern hashing algorithms like SHA-512, bcrypt, scrypt, and Argon2. A step-by-step comparison of the crypt module vs. passlib, including timing the effect of different numbers of hashing rounds (e.g., 5000, 100,000, and 1,000,000 rounds). Best practices for securing your application using modern password hashing techniques. Who is this video for? Python developers looking to upgrade their password hashing methods. System administrators who manage user authentication and want to enhance security. Anyone curious about cryptography, password security, and why password hashing is critical. By the end of this video, you'll understand why using outdated libraries like crypt is a risk, and how passlib can help you implement strong, secure password hashing in your Python applications. 00:00 - Introduction 01:15 - Password Hashing 04:01 - Shadow File 07:09 - Understanding SALT 14:07 - Life After Crypt 25:04 - Measuring Performance Additionally you can find my video courses on Pluralsight: http://pluralsight.com/training/Autho... and take time to see my own site http://www.theurbanpenguin.com
