The Data Encryption Standard (DES) implementation used for encrypting/decrypting blocks of bits. This program implements the complex algorithm in C++.

Encrypt messages using the Enigma machine (TUI version)

The SMART Voting System in C++ implements efficient data structures and algorithms for a streamlined and secure voting process. It offers admin & voter interfaces for managing voter information, casting votes, monitoring the process, and ensuring accessibility and reliability with secure password storage, and real-time notifications.

Codes for my Information-System-Security Class

This project analyzes the performance of different cipher suites supported in the Transport Layer Security (TLS) 1.3 protocol when used in wireless sensor networks (WSNs). WSNs have resource constraints like limited computing power, memory, and battery life.

Gematria Analyzer is a Gematria calculator who takes word and phrases and compare it to dates and solar eclipses. Created with Qt Creator 5.14 Community, works on DMY and MDY. Expose news and events with this neat little program to decode the headlines.

Here is some DR.Mohammad EL-Ramly Ciphers , I have implemented 9 different algorithm to encrypt the sentence

Cipher program to encode and decode the secret message. In this program I have only use character and spaces but it have anything like numbers, symbols and etc.

rot13 in c++

A simple console app with Caesar and Vigenère cipher algorithms, for a school assignment.

Simplified Data Encryption Standard (S-DES) is a simple version of the DES Algorithm. It is a block cipher that takes a block of plain text and converts it into ciphertext. It takes a block of 8 bit. It is a symmetric key cipher, they use the same key for both encryption and decryption. We take a random 10-bit key and produce two 8-bit keys.
