Bonus Installment

Edited 2021-12-25 to add: The prize offer expires after 2022-02-28

Because I missed Thursday, here’s a bonus installment. It’s a series of five #cryptopuzzles. Increasingly difficult, so I suggest trying them in order.

Classics for Torture!

I take pleasure in torturing my friends!

At the upcoming BSidesROC, some of the Capture the Flag challenges will be of my own devising, and I am a fan of classic encryption techniques, some of which date back to ancient times.

These encryption schemes are no longer useful for serious applications, as computer cryptanalysis will brute-force them in milliseconds.  Still, for the occasional geocaching puzzle or other casual, fun pursuits they are great. (The contest is over, by the way.)

Here’s one for you:

Happy Puzzling!

Gotta Be a Clue!

Maybe I have been playing too many room-escape type puzzles lately?  Because “That HAS to be a clue!” was my first thought when I saw this today.

Puzzle Day!

Cube

It’s today!  Happy International Puzzle Day!  (Unless you believe those July 13 cranks.)

In honor of which, here’s a cryptogram I created for your puzzling pleasure:

ADDAA DDADD DADGA FXADX VFDDF AAXFD VAADA DXDDG DXAAX GAXFA 
DXFVD FXVDF XVDFX VFFGF VGVVF GFFFD VFAVV AAFDV AGFVV GAFAX 
VDDAF AAGFG FFFGG GFGDA DGVVA AXAFA FFAVD VGGFG VGAGF FGGDV 
FVVVV XVFVD ADGVV DGVVD GVDDF XAGVF DFDDA VAFFX DVGVA GFADG

AAFDX GDFAV DDVDX DDAAA XAAAG AAAVD DDAAA AFAXD AADDD AADXG 
DAXGX ADDDA ADADD GAAAD

Now I hear from people that these are hard.  I don’t want this to be hard, so I made it easier by posting the crypto keys publicly.

Find them, and then have at it! (Submit answers here)

Prize is only bragging rights; I will post the winners  next week.

 

One More Puzzle!

Who loves puzzles?  I love puzzles!  I especially love making puzzles.  So I made this one for you to solve.  Submit the correct answer to today’s puzzle for a delightful prize.  This is a picture puzzle: the image will lead you to the instructions on how to submit the correct answer.

no-no

A one-year subscription to LastPass Premium will be awarded to each of the first two submitters of the correct solution to this puzzle.
