A demo project to demonstrate how DES encryption/decryption works.

This repository contains a steganographer web application that allows users to encode and decode text messages within image or audio files.

This app securely encrypts and decrypts your files by generating keys using the AES algorithm.

Optimize AES encryption for storage efficiency on GitHub. Our solution segments data, reduces encryption rounds, dynamically sizes blocks, and applies compression, achieving up to 45% storage savings while maintaining AES security standards. Ideal for storage-constrained environments and large-scale data applications.

Projeto da disciplina SI01033 (Segurança em Redes de Computadores) do Curso de Sistemas de Informação da Unifesspa para exercitar os conceitos de criptografia (simétrica e assimétrica) e hash criptográfico

Multi-User Telegram Task Manager Bot stores data and secures it with symmetric encryption.

Secure communication protocol using RSA encryption, digital signatures, and symmetric encryption. It ensures secure message transmission over a Teams chat platform by encoding messages in hexadecimal strings. The protocol involves key generation, random byte generation, key exchange, signature verification ...

This is a simple example of AES encryption (with 128, 192 and 256bit keys)
