Encrypts or decrypts a string of text to a string of characters based on a user-specified encryption key. Discussion: The function makes use of bitwise Xor comparisons on the string to be encrypted and a string

The AES encryption and decryption can be implemented based a string parameter. When creating a Cipher instance, you need to specify the algorithm specifications in a string parameter. The string parameter consists of the symmetric key type (algorithm and key length), cipher block mode, and padding...
DecryptThe file encryption technology protects a private file so that only the valid user can read that file. This paper surveys the current file encryption and decryption algorithm, and compares them. The analysis results can prove that advanced encryption standard (AES) is a good choice for ...

The Hill Cipher is a polygraphic substitution cipher that uses matrix algebra to encrypt and decrypt messages. This implementation of the Hill Cipher in Python uses the NumPy library to perform matrix operations. Installation Clone the GitHub repository: git clone https://github.com/Jawabreh0/hil...
Problem 3 [8pt] RSA is an algorithm used by modern computers to encrypt and decrypt messages. The core of RSA is the computation of (pk mod n) where k is confidential (i.e., with k, an attacker can derive the private key). For effic...
Based on a fixed 56-bit symmetric key, this algorithm creates a single key based on a binary number used to encrypt and decrypt data. Using a block cipher methodology, it uses 64-byte blocks to randomly populate a key. Currently in use by organizations such as the National Security Agency...
