How SHA-2 Works Step-By-Step (SHA-256)

child looking at stair steps

SHA-2 (Secure Hash Algorithm 2), of which SHA-256 is a part, is one of the most popular hashing algorithms out there. In this article, we are going to break down each step of the algorithm as simple as we can and work through a real-life example by hand. SHA-2 is known for its security (it … Read more

(Very) Basic Intro to Hash Functions (SHA-256, MD5, etc)

Hash functions are used to securely store passwords, find duplicate records, quickly store and retrieve data, among other useful computational tasks. As a practical example, all user passwords on Qvault are hashed using Bcrypt to ensure that if an attacker were ever to gain access to our database our user’s passwords wouldn’t be compromised. I … Read more
