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.

This repository contains my resolutions of the set of problems of the Cryptopals challenges.

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.

AES256-GCM file encryption

This project provides User-Defined Functions (UDF) for MySQL, enabling encryption and decryption of data using the OpenSSL library. The functions support various encryption algorithms and allow the use of optional custom IVs (Initialization Vectors).

Free cross-platform deniable encryption cryptoarchiver

Password Manager is a command-line interface (CLI) application written in C++ that securely stores and manages your passwords. Utilizing AES-256-CBC encryption provided by OpenSSL, this simple yet effective tool ensures your passwords are stored securely and can be retrieved when needed.
