Numpy is a library which provides support for large multi-dimensional arrays or matrix data structures in Python. The efficient and high-performance handling of large arrays makes numpy ideal for scientific and mathematical applications. This also makes numpy arrays an good data store for large, sin...
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...
