The International Conference on Cryptology and Information Security in Latin America, LatinCrypt2025, was made in Medellín on October 1-3 of 2025 and organized by Universidad Nacional de Colombia and Universidad EAFIT in collaboration with the International Association for Cryptologic Research (IACR).

The complete event started with two schools: on September 26-27 with CatíoCrypto, and with ASCrypto on September 29-30. And finished with the main conference on October 1-3.

The present repository contains all the information about the poster I presented there and, also, class notes about different topics as Elliptic Curves, Isogenies, Secure Multi-party Computation and Zero-Knowledge.

The poster is titled as Pedagogy behind cryptology CTF challenges and a way to improve them. All the information can be found in the poster directory.

Class notes are from CatíoCrypto, ASCrypto and some from the paper explanations in main conference or about other poster presentations that I liked. More information about that can be found in the class notes directory.
