Dimitrios Mamakas's repositories
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.
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.
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.
dmamakas2000
Demo repository used to introduce myself to the public 🙂
ethereum-sos-solidity
In this repository, we implement a complicated version of the SOS-Game, in an Ethereum smart contract using Solidity. The contribution, splits into two APIs, which are finally combined to achieve the wanted functionality.
filter-ppm-cpp
This is a fancy description. It will be updated later.
