cryptanalysis-python

In this project, we experiment with the use of diverse cryptographic algorithms. First, we attempt to encrypt a plaintext message using the Vigenère Algorithm and a fixed-length encryption key. Afterward, we experiment with the decryption of the produced cipher using Kasiski's Method, as well as the Index of Coincidence statistical test.

ipo

This GitHub repository implements a novel approach for detecting Initial Public Offering (IPO) underpricing using pre-trained Transformers. The models, extended to handle large S-1 filings, leverage both textual information and financial indicators, outperforming traditional machine learning methods.

nllp-2022

In this repository we generally experiment with the creation of Transformer-based models which use TF-IDF embeddings, for large legal document classification.

sql-injection-spring-security

This repository implements the scenario of a SQL injection attack on a custom web server, using the Spring-Security Framework version 6.1.2, Spring-Web, Gradle, PostgreSQL for the management of the created database, Lombok, Thymeleaf, and Guava.
