Dancing Offbit: The Story of a Single Character Typo that Broke a ChaCha-Based PRNG

Random number generators are the backbone of most cryptographic protocols, the crucial cornerstone upon which the security of all systems rely, yet they remain often overlooked. This blog post presents a real-world vulnerability discovered in the implementation of a Pseudo-Random Number Generator (PRNG) based on the ChaCha20 cipher. Discovery of a biased PRNG During a […]
