May 8 2022 — On February 2 2020, I felt the urge to speak to my best friend. What kind of life is waiting for us? Will our societies learn from this pandemic? Or will our world be just the same, but even worse? Follow us on Twitter: @INTEL_TODAY

So, I wrote a short poem. Of course, I encrypted my message for her before I sent it.
A man is never too careful!
Can you read this poem?
OK. I will give you some help… I encoded the message with a Vigenère table.
For the KEY, I used PALINDROME, and I chose ZEUGMA as the passphrase.
Building the Vigenère Table
Decoding the Poem
This is very easy. First you write the encrypted text as I did below. (Here I just wrote the first 12 characters.)
On the second line, you write the passphrase (ZEUGMA) and you repeat it until you reach the end of the cipher.
Now, look in the Vigenère table which letter encoded with a Z gives a P? That is A! (in RED)
Which letter encoded with a E gives a J? That is R! (in BLUE)
Which letter encoded with a U gives a I? That is E! (in GREEN)
And you just keep going till all the cipher is decoded.
And the poem is…
A R E W E N O T A N N A D R A W N O N W A R D W E F E W D R A W N O N W A R D A N N A T O N E W E R A
So, yes, the poem is a palindrome. You can read it forward and backward just the same.
It is also a rather cute zeugma…
And time will tell us the answer!
