'Codebreakers' Author on the Undecipherable

Friday, April 08, 2011

In 1999, the body of 41-year-old, high school dropout Ricky McCormick was discovered in a St. Charles County, Missouri cornfield. There were no weapons, no motives, no suspects in the case. The only clue investigators had were two hand-written documents found in the pockets of the victim's pants, a scrambling of letters that read like an encoded message.

After more than a decade, the FBI still has not been able to crack the code and now they've enlisted the help of the public. But thousands of submissions later, even the best cryptologists among us are stumped. For a closer look, we hear from David Kahn, author of "The Codebreakers: The First Comprehensive History of Secret Communication from Ancient Times to the Internet." David Kahn says his favorite code is the "one time code." This type of encryption is impossible to crack, and depends on a secret and random key.

Hello from Spain
If it is a letter, signature of the author should be at the end (2nd note)

–In my humble opinion the master key is in the 2nd note, last line.
–I see that: “O-W-m-4 H8L XORLX”

Can you see which letters aee repeated and where?
Can you remember the Arthur´s C. Clarke joke about HAL 9000?

Yes? Then my solution is……
+If O=O, W=W and R=R
+If m=N, H=I and L=M using Caesar Code B or +1 move
+If X= Variations of the letter “C” (MC,C and KC) using shorthand
+If 4= four= FOR by phonetic solution like SMS language.
+If 8= eight= eit= ei= letter “A” by phonetic solution like SMS language (example L8= late or leight, H8= hate ….)
+If the hyphen join the letters in a word.
+If we add vowel “i” by transcription shorthand solution.

“O-W-m-4 H8L XORLX” means “OWN-FOR I AM MCCORM(i)CK”.

It is the signature, last will or testament of Mccormick.

+ If you think “4″ is not “4″ but “y”
+ If you think “8″ is not “8″ but “I” then the solution is:

“Y”= wai= WHY or WAY by phonetic solution, similar sound.
“I”= ai= letter “A” by phonetic graphic representation.


Merry Christmas.
