👨‍💻 🔐 📈 A project based in (Classical) Post-Quantum Cryptography, namely in Lattice-Based Cryptography. This project was built using Jupyter Notebook, SoS (Script of Script) Notebook, Java, Python, Bouncy Castle library, and TeX. The goal of the project was the study and analysis of the CRYSTALS public-key (asymmetric) cryptographic suite.
