Texts: My name is Angel.
On your own, create a new text file called Send.txt, apply an MD5 hash to the file, and then use GnuPG to encrypt and decrypt it. In your Challenge Questions file, include screen captures to document the steps you followed.
a. Create a new file called Send.txt and add the following text: My name is yourname, replacing yourname with your own name. (Hint: Refer to Part 1 of this lab).
b. Add an MD5sum hash to the file and record the string in your Challenge Questions file (Hint: Refer to Part 2 of this lab).
c. Share the student's public key with the instructor account, so the instructor can send encrypted messages to the student account (Hint: Refer to Part 5 of this lab).
d. Using the instructor account, encrypt Send.txt using GnuPG (Hint: Refer to Part 6 of this lab).
e. Copy the file to the student's home folder, change the permissions on the file, and then decrypt Send.txt using the student account.
f. In your Challenge Questions file, include screen captures of the commands used to encrypt and decrypt the Send.txt file.
Part 3: Challenge Exercise
Not all encryption methods require an encryption key pair. AES256 requires only a shared passphrase and the correct syntax. Use the Internet to research the correct syntax for using this encryption method with GPG and complete the following tasks to encrypt and decrypt a new file. Make screen captures to record your progress.
a. On TargetLinux01, log in as the student and create a new file called yourname.txt, replacing yourname with your own name, and add the following text: This is a test of AES256 encryption.
b. Use AES256 encryption with GPG to encrypt the file and remove the original file from the directory, leaving only the encrypted version of the file using the encryption passphrase.
