Debarshi Kundu

Student. Programmer. Hacker.

I study computer science, build software, and spend my free time taking things apart to see how they work. This is where I document the useful parts.

Things I've built

A few projects that show how I think, not just what I can type.

cryptor

Maintained

A small Python encryption and decryption tool built to understand how cryptographic primitives behave in practice.

  • Python
  • Cryptography
  • CLI

All projects

Notes from the lab

CTF walkthroughs, experiments, and things I broke on purpose.

The first writeup is in progress. In the meantime, the projects page is the best place to start.

All writeups

What I'm up to

Building
This site, plus a small security tool I'll write up when it stops setting off my own antivirus.
Learning
Python internals, Rust, and the parts of systems programming that don't fit in a semester.
Practising
CTF challenges and lab machines — web exploitation and reverse engineering, mostly.
Looking for
Software engineering or security internships where I can ship real things.

Let's build something, or break something.

I'm open to internships, collaborations, and interesting problems. The fastest way to reach me is email.
