Three high school friends who took different paths after high school are now all enjoying retirement. Each one settled for a different job but all enjoyed cryptography throughout their lives.
Now having reunited they send each other encrypted messages to keep their minds sharp and prevent their knowledge from dwindling.
- One spent his life in the military.
- Another in the police force.
- The last a telecommunications company.
Currently they communicate using a homemade cipher they can all relate to.
!3B7BA2B3C 1CF 7A9A3B2ABD1F A7A1B 7A9A3B2ABD1F 7A2B7C2BD B7A1B. !C4A 1C2E E1A2CB1F 3B7BA2B3C 2E7B 2AB 6A1AEE3C, C7B9A2D 1F2B1A2D3A6A 4A7B2D 6A1AEEC7A2B1FF 0A1CDD 7A2B7C2BD B7A1B.
Can you crack their latest message???
To complete the problem you must:
- Decrypt the message and find the author. - Explain clearly how the cipher works. - Explain what the cipher is based on.
After a few days I will post some more hints if this remains unanswered.
They all share practical knowledge, they have been known to mumble.
The last thing they want to do is meet up, they are in their element.
They also like to abbreviate, time is of the essence.
Read between the lines systematically, these hints are not what they seem.
What is the solution to verbal communication errors?
Shall I spell it out for you? Perhaps.
Nate! Oh My Gosh, Get It Over With!
PLEASE NOTE: I have updated the cipher text due to minor errors.
