This repo will contain the algorithms for encryption and decryption of messages and ciphers respectively !!

A python package to seamlessly encrypt and decrypt data into many rich cryptography algorithms

Hung-Yi Lee Linear Algebra 2018 Fall Homework

A Hill Cipher Cracker that performs automated crib dragging given a known plaintext and a ciphertext.

Some classical/modern ciphers in C language and Python to encrypt and decrypt important information and keep the information safe, such as integrity, authentication, confidentiality and availability of the data. Some implemented ciphers are: Affine, DES and AES (with modes of operation for BMP images)

Implementation of various symmetric key encryption systems like AES, DES, triple DES (3 DES), Ceasar cipher, Substitution cipher, Hill cipher

Hill cipher implementation in Python

A bot to encrypt and secure your text files locally, using a 4-digit PIN.

CSCI 55500 Cryptography

Security Package is a package that includes several security modules - Ciphers, Image Encryption and Decryption, Audio Encryption and Decryption, Steganography, Background Removal, OTP Generation and Authentication.

Cryptographic algorithms implemented in python and tkinter library

The Hill-ADN Cryptography project combines Hill cipher methods with DNA encryption, offering a novel approach for improved data security. It includes binary to DNA conversion, amino acid translation, and Hill cipher encryption, with the decryption process addressing genetic code ambiguity challenges.

Trabajos presentados como parte del curso de Criptografía y Seguridad, impartido por el profesor Manuel Díaz Díaz durante el semestre 2023-1 en la Facultad de Ciencias, UNAM.

This repository contains the algorithm for the Hill Cipher encryption which use the matrix to encrypt the message and even to decrypt it using the inverse of the same matrix ,this algorithm uses the python program to implement it and of course we can use any language to implement it ,

Crack traditional ciphers through dictionary attacks

GTU Information and Network Security ( INS ) in python .

Encipher/Decipher Plain Text using Hill Cipher Algorithm

Criptosistema de sustitución poligráfica que utiliza el producto de matrices para realizar las operaciones, este que se basa en emplear una matriz como clave para cifrar un texto en claro y su inversa para descifrar el criptograma correspondiente.
