AES, DES, ECB, CBC: When Random-Looking Bytes Still Leak Structure

2d ago · 7 min read · This is Part 4 of the KL divergence experiment series. The earlier posts showed that hashes and some encryption outputs can look close to uniform at the byte level, while weak classical ciphers often

Why Unigram KL Is Not Enough

2d ago · 6 min read · This is Part 3 of the series on KL divergence, hashing, and encryption outputs. The first two posts used byte frequencies as the main lens. That worked for plaintext, hashes, and some weak ciphers, bu

Ancient Ciphers Hide Text, But Do They Destroy Structure?

2d ago · 6 min read · This is Part 2 of the KL divergence experiment series. Part 1 showed that hashing a wordlist makes the byte distribution look much closer to uniform. This post asks a messier question: what happens wh

Does Hashing Make Text Look Random?

2d ago · 6 min read · This post is the first part of a small experiment series on statistical structure in text, hashes, and encrypted data. The question is simple: if I take a list of English words and hash each word, doe

Building a Furuta Pendulum - Part 5: Final Notes, LQR, and Handoff

4d ago · 11 min read · This is the final post in the Furuta Pendulum series. The project started as a Design Lab built at IIT Kharagpur. We designed the hardware, assembled the setup, wrote firmware, tested the sensors and
