__GusCrypt 1.0v_Encryption Program

				
//**************************************
// Name: __GusCrypt 1.0v_Encryption Program
// Description:Easy way to encrypt and decrypt any type of files, with password protection.
// By: Gustavo Moraes
//
// Inputs:Tell what file to be encrypt/decrypt,Whats the new file, and what password you want to use.
//
// Returns:A totally encrypted file impossible to decrypt without the password.
//
// Assumes:Easy code, only need to know the basics of c/c++
