Part $1$: Encrypting Messages with OpenSSL

OpenSSL can be used as a standalone tool for encryption. While many encryption algorithms can be used,

this lab focuses on AES. To use AES to encrypt a text file directly from the command line using OpenSSL,

follow the steps below:

Step $1$: Encrypting a Text File.

a$.$ Start the Security Workstation VM and log in with username sec$\_$admin and password net$\_$secPW$.$

b$.$ Open a terminal window.

c$.$ Because the text file to be encrypted is in the $/$home$/$sec$\_$admin$/$lab$.$support.files$/$ directory, change to

that directory:

$[$sec$\_$admin@secOps ~$]$$ cd $/$home$/$sec$\_$admin$/$lab$.$support.files$/$

$[$sec$\_$admin@secOps lab.support.files$]$$

d$.$ Type the command below to list the contents of the encrypted letter$\_$to$\_$grandma.txt text file on the

screen:

$[$sec$\_$admin@secOps lab.support.files$]$$ cat letter$\_$to$\_$grandma.txt

Hi Grandma,

I am writing this letter to thank you for the chocolate chip cookies you sent

me$.$ I got them this morning and I have already eaten half of the box! They

are absolutely delicious!
