Encrypting library and Vim wrapper to encrypt file

Encrypt and Decrypt demonstration using RSA with OpenSSL using the Qt framework!

P.A.C.K.E.R is a simple DRM software that can grant and verify serial keys, encrypt & decrypt [RSA & AES] your software. It also has modules to protect your executable (by injecting a thread and an attachable DLL) for anti-debugging purposes.

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

A client-server CLI chat application that encrypts messages between client(s) and a server using AES-Cipher Block Chaining encryption

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.

Free cross-platform deniable encryption cryptoarchiver

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).

AES256-GCM file encryption

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 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.

A Windows utility to check for potential insecure paths used by the OPENSSLDIR build parameter in OpenSSL libraries

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