Some messages are meant to be kept secret

 

The Zimmermann telegram, encrypted above by the German Foreign Office, was supposed to be secret, but British Intelligence during World War I broke the code. That was good news for Texas, Arizona, and New Mexico which the German Empire had promised in the telegram to return to Mexico if Germany met its objectives.

 

Let's use the telegram as an example of how to really secure a message.

Highlight a confidant, choose message encryption

 

Highlight in your roster the person that you are going to send it to. Click Encrypt Message.

Type or paste a message

You are shown this page with an area into which you can type or paste a message. Again, under the heading there is a reminder of who your confidant is.

 

 

Let's copy into our clipboard (Ctrl-A, Ctrl-C) the plain text Zimmermann telegram from wherever it is found. Then click here in the text area, and input Ctrl-V to paste in the entire message.

 

 

The message is long, so scroll down if you wish to see more.

 

 

Scroll down even further if you wish to see the last part.

 

File version of the encrypted message

When you are happy with what you see, click Encrypt This Message. You are shown:

 

 

Notice how messages are named ... "Msg_" followed by four digit year and two digit month, then underscore and the three letter version of the month, underscore, day, underscore, time of the message in two digits each for hour, minute, and second when the message was encrypted. That's followed by .enc (encrypted) and finally .txt (a text wrapped version of the message). Why is the month shown twice? That's so that a list of messages in alpha order will also be in date order. The 24 hour clock is used, so an hour value of 15 means 3 p.m. Notice also that messages are automatically text wrapped for convenience.

Extra display of the encrypted message

Click OK. You have the file and are good to go. But if there are no accented letters and if the length is reasonable, you see extra information -- the encrypted text wrapped message.

 

 

From here, normally you would click either encrypt another message or to go back to the roster.

 

Notice the instructions on the page if you want to copy the message and share it conveniently, yet securely, with the selected confidant (person or team). Click in the message, press Ctrl-A, then Ctrl-C. If you have a social media page or a page open in a word processor, click there and then input Ctrl-V. The following is what you would see:

Invite your friends to decrypt that! Better yet, ask British Intelligence to encrypt it. Even if they know that these 864 characters are the Zimmermann telegram, our bet is that they won't be able to decrypt the message, no matter how much computer resources they use for the task.

 

We will use this same encrypted message again in the next page of helps.
