(Very) Basic Intro to the Scrypt Hash

Scrypt is a slow-by-design hash function or more accurately, a KDF function. Its purpose is to take some input data, and create a fingerprint of that data, but to do it very slowly. A common use-case is to take a password and create an n-bit private key, which is much longer and more secure. Here … Read more (Very) Basic Intro to the Scrypt Hash

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

This is going to be a basic introduction to hash functions. I will assume most of my audience is here to gain an understanding of why hash functions are used and the basic idea of why they work. My goal is to explain it in a general sense, I will be omitting proofs and implementation … Read more (Very) Basic Intro to Hash Functions (SHA-256, MD5, etc)
