Cryptography Trends And News Going Into 2020

Quantum Computing While quantum computing may not be coming quite as fast as some in the field had feared (or perhaps hoped), Google did solve an impressive problem this year. They published a paper in Nature stating that their quantum processor solved a problem that a digital computer would take 10,000 years to solve. The problem that was solved deals …

Cryptology, Cryptography, and Cryptanalysis – Get your Vocabulary Straight!

Many new developers are jumping right into coding (usually for those fat paychecks) without learning much about the history of Computer Science. Alan Turing, regarded as the father of Computer Science, was first a cryptologist and mathematician and pioneered the field of CS in order to solve cryptological problems. In this article, I will go over common crypto-related definitions for …

Randomness and Entropy in Node and Electron

Randomness is a hard problem for computers. For this reason most functions that generate randomness are not considered cryptographically secure. That means that it is possible that an attacker can take a good guess at what number a non-secure randomness generator generated. How can randomness be attacked? Many non-secure randomness (or entropy) generators would do something similar to the following: …

(Very) Basic Intro to the Scrypt Hash

This will be a basic introduction to the Scrypt hash function, or more accurately, KDF function. I will assume most of my audience is here to gain an understanding of why Scrypt is used and the basics of how it works. My goal is to explain it in a general sense, I will be omitting proofs and implementation details and …
