Cryptography Algorithms

Improved way of securing data using combined Steganography and Cryptographic techniques

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
