The program must read the input file names as command line arguments or parameters. The first input parameter will be the name of the encryption key file. The second input parameter will be the name of the file to be encrypted. The program should open the two files, print the inputs to the screen, and output ciphertext to the console. In the event that there is not enough characters, the last block should padded with the letter x. More info can be provided as needed. very easy job

Hi, I have written programs with this cipher before, so it will be a piece of cake. Please contact me. I want to know how large the key is and is the file to be encrypted in ascii? Cheers, Jason

Hello. I can create a encryption app for you. If I'm not mistaken a Hill cipher uses matrix to encrypt and it's inverse to decrypt. Message me back so we can discuss it. Thanks. --Vinicius Zolin
