List the steps that you and your friends will need to take. You can assume that FileVerifier++ has been installed on computers of both of yours. The steps that me and my friends need to take are:I will first create a hash file the file that file I want to send to my friend in a foreign country.Then I will cross check the hash file with the FileVerifier++ which is installed in my computer just to cross check if all the file are flagged as valid. After FileVerifier++ shows that the file is valid then I will send the file to my friend and notify him to check the file I sent using FileVerifier++ installed in his computer.After verifying the file if the verification report is flagged as invalid then it means the file is corrupted which means the file is modified or tampered after it is sent and before it is received by my friend and I will immediately check the connection for and hackers.after Im sure about the connection I all hash the file again and the file to my friend and I do the same until he the file is flagged as valid when verified by my friend.
