Password Hashing and Storage
In this video, we're going to explore the theory behind password hashing and password storage. We'll start off with a rundown of cryptography, including hashing and encryption for security, as well as encoding, such as base64 and hex, for transport. We will then go through the typical password verification flow and discover several hashing algorithms used for passwords, including bcrypt.
As you will find out, there are a few nuances related to the bcrypt algorithm; we will promptly touch on those too. Next, we will highlight the most common password attacks, and establish how to protect our password hashes against them using a salt and a pepper. Finally, we will close up with an overview of various password hashing strategies that combine hash functions and encryption algorithms alike.
