For this exercise you have to remember that you already have the encoded key and the message.

So, the first step is going into your mail to decode the key.

Those are steps 7-12 from the practice. Now you can follow steps 20-27 to finish decoding the message and using the decoded key to decrypt the message.

Some of the steps will be slightly changed so do not use the exact commands.

Example: in the final decryption for the message the key will not be “keyforjohn” if you followed the above steps exactly when decoding the key.
