A little curiosity.
A working cipher.
My work lives where curiosity becomes a system: applied cryptography, security research, AI and the infrastructure underneath.
This small experiment uses your browser’s Web Crypto API. Change the message, encrypt it, then verify the round trip.

VIT CHENNAI / CLASS OF 2027
I’m Hanish, a final-year Computer Science student specialising in AI and Robotics at VIT Chennai.
Security drew me toward cryptography and systems. AI gave me another set of questions: how models remember, how they fail, and when a plan is actually useful. I like working across those boundaries.
That curiosity also turns into Linux distributions, Blender tools and hypercasual games. Away from the screen, it’s the electronic keyboard, sport, a growing Pokémon card collection, and a good case study.
