Programming Language: C++

Instructions:

1. To compile, simply, type "make" at the terminal (without the quotes).

2. To run the program type "./cipher <ENG/DEC> "

   : Name of the cipher to use. Valid names are: AES DES : The encryption key to use - must be 16 characters. <ENC/DEC> : Choose wheter to encrypt or decrypt, respectively. : the file from which to read the input. : the file to which the output shall be written

Notes:

-in.txt, small.txt, big.txt were used as input testing files, out.txt was the output file -padding may be randomly added when encrypting the large file, resulting in a few Extra characters at the end.
