Deep Dive into Shannon Entropy: Evaluating Password Strength Mathematically
An in-depth look at using Shannon's information theory to measure password entropy and build reliable cracking-time estimations under realistic brute-force constraints.
Cybersecurity Engineer & Defensive Developer building secure, resilient backend systems. Experienced in threat boundary checks, applied cryptography, and secure REST APIs with a focus on performance and clean architecture. From reducing latency to auditing files, I build defensive solutions that stand up to adversarial constraints.
Source-verified software defense suites, file inspectors, and microservice authentications created under internship constraints.
