GUI application built with Qt and C++ that lets you cipher text messages and allows you to decipher them back too

Crack legacy zip encryption with Biham and Kocher's known plaintext attack.

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.

DES takes a 64-bit plaintext and creates a 64-bit ciphertext during encryption and takes a 64-bit ciphertext and creates a 64-bit block of plaintext during decryption. A 56-bit cipher key is used for both encryption and decryption.

bl4ckbo7 Cipher is a Monoalphabetic Substitution Cipher, which can encrypt and decrypt plaintexts.
