This project implements a simple Encryption and Decryption system using two classic ciphers: Playfair Cipher and Vigenere Cipher. The implementation is done using HTML, CSS, and JavaScript, and the ...

The Playfair cipher is an incredibLe code system that is both difficult to decrypt without a computer and easily solvable by hand. Here's how to solve it.

Overview This project implements a Playfair Cipher encryption tool using Html,Css,JavaScript. The Playfair Cipher is a cryptographic technique that encrypts plaintext into ciphertext by using a 5x5 ...

In 1854, Sir Charles Wheatstone invented the cipher known as "Playfair," named for his friend Lyon Playfair, first Baron Playfair of St. Andrews, who popularized and promoted the cipher. Its ...

Cryptographic systems are either symmetric or asymmetric. Symmetric cryptographic systems use one common key for both encryption and decryption. Asymmetric cryptographic models use different keys, one ...
