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 …

According to Authy: 2FA is an extra layer of security used to make sure that people trying to gain access to an online account are who they say they are. Usually the …
