Giacomo Pope

Theoretical physicist, turned aspiring cryptographer. I am primarily interested in the application of elliptic curves in public-key cryptography.

Co-founder of CryptoHack: a free education platform for learning modern cryptography.
Cryptography consultant with NCC Group.
Ph.D. in theoretical physics, my work was devoted to better understanding black hole solutions of N=2 supergravity and their thermodynamics.
Compete in CTFs with Organizers.
- I have included Writeups for the challenges I have either written or solved from various CTFs.
