The project is a menu-based system for selecting encryption techniques (symmetric, asymmetric, hybrid). It covers classical ciphers, their advantages and disadvantages, and analyzes the most efficient ...

Abstract: The Symmetric and Asymmetric Cryptographic techniques and algorithms as existing in the literature are either too simple and traditional or too complex to code and understand. In the current ...

This project implements the Playfair cipher, a classical symmetric encryption method. The program uses a 5x5 table to encrypt and decrypt messages, where the letter "W" is replaced by "V" and ...

Although most users don’t know it, their Web browser plays a key part in determining the strength of the ciphers used between their client and an HTTPS-protected Web site. Encryption ciphers used in ...

The same secret (private) encryption key used by both sender and receiver. Contrast with asymmetric cipher, which uses a public and private key. See secret key cryptography. THIS DEFINITION IS FOR ...
