Run on a Windows machine

How it works: THe Hill Cipher method is utilized to encrypt a phrase the user provides. The program utilizes math concepts such as matrix multiplication in order to encrypt the phrase with a randomly generated key. Once the phrase is encrypted, a file is generated and stored to a user-specified location. The same program has a decryption mode to decrypt the generated file

Enjoy!

I worked on the encoding part of the project. This encapsulated placing encoded letters and symbols into matrices.

I worked on the decryption aspect of the project. After the inputted message is encrypted and sent out to a new file, I manipulated the RNG matrices, by inverting the numbers within the matrices used during the encryption period, in order to reverse and therefore read the encrypted letters from the created file and display the original message. By working on this project, I not only learned more about matrices and their applications, but I also learned much more about C++ and file interaction.
