Demo of quantum cryptanalysis combining Shor's Algorithm for RSA factorization with Quantum Neural Networks for cryptographic security assessment, running on real IBM quantum computers.

Set of scripts to build OpenSSL for Android on macOS

example using openssl implementation of SHA-3 - calculates SHA-3 digest of data read from stdin

Project for the course of Foundations of Cybersecurity (2023)

C Programs for Miscellaneous Purposes

Simple benchmarking tool to compare the standards AES, CAMELLIA and SM4

ISA Project - POP3 Client with TLS support, FIT@BUT 2021

A Windows app that uses a customized libjingle library to stream music in real-time

a security oriented CLI password manager written in C

Zęby W Zasięgu - Enginieering Thesis Source Code

This C++ program demonstrates a basic blockchain implementation using OpenSSL for SHA-256 hashing. Each block stores transaction data, a timestamp, and a nonce. Proof-of-work is used to mine blocks with a difficulty target.

Prebuild pod - OpenSSL TLS/SSL and crypto library

File encryption / decryption utility software written in C.

Encrypting library and Vim wrapper to encrypt file

Creating a HTTPS Client and understanding how the TLS and HTTP protocols work along to generate a secure communication via the web, using SSL certificates.

The Open Quantum Safe OpenSSL packaging repository

A C++ WebSocket server library wrapped for seamless use in Go applications. Supports concurrency, SSL, and JSON parsing via Boost, OpenSSL, and nlohmann_json. Perfect for real-time systems like chats, live updates, and IoT, enabling efficient cross-language workflows.

This is a stand-alone utility that uses openssl crypto-library for secure communication. 📁 🎩

A minimal, production-oriented HTTPS server built entirely in C using POSIX sockets and OpenSSL, following Clean Code principles, KISS philosophy, and modular architecture.
