DMRIPFEIMEHNLSSTTRTVDOHWX?

Note: This Includes The Final Character "X" That Was Excluded From The Sculpture By Mistake. Jim Sanborn Has Verified This To Be His Error.

Key: None

Method: Shift & Skip Cipher (Decode)

Shift: 252

Skip: 1

Step 1: Start with the original cipher string:

"ENDYAHROHNLSRHEOCPTEOIBIDYSHNAIACHTNREYULDSLLSLLNOHSNOSMRWXMNETPRNGATIHNRARPESLNNELEBLPIIACAEWMTWNDITEENRAHCTENEUDRETNHAEOETFOLSEDTIWENHAEIOYTEYQHEENCTAYCREIFTBRSPAMHHEWENATAMATEGYEERLBTEEFOASFIOTUETUAEOTOARMAEERTNRTIBSEDDNIAAHTTMSTEWPIEROAGRIEWFEBAECTDDHILCEIHSITEGOEAOSDDRYDLORITRKLMLEHAGTDHARDPNEOHMGFMFEUHEECDMRIPFEIMEHNLSSTTRTVDOHWX"

Step 2: Take the remaining part of the full string after counting 252 characters, and place it on top of the original cipher string. 

The new string should look like this:

"SFIOTUETUAEOTOARMAEERTNRTIBSEDDNIAAHTTMSTEWPIEROAGRIEWFEBAECTDDHILCEIHSITEGOEAOSDDRYDLORITRKLMLEHAGTDHARDPNEOHMGFMFEUHEECDMRIPFEIMEHNLSSTTRTVDOHWXENDYAHROHNLSRHEOCPTEOIBIDYSHNAIACHTNREYULDSLLSLLNOHSNOSMRWXMNETPRNGATIHNRARPESLNNELEBLPIIACAEWMTWNDITEENRAHCTENEUDRETNHAEOETFOLSEDTIWENHAEIOYTEYQHEENCTAYCREIFTBRSPAMHHEWENATAMATEGYEERLBTEEFOA"

Step 3: Decryption

Starting from the first character of the new string, write down every 252nd character until you reach the end of the new string. Then, starting from the first character of the original string, write down every 252nd character until you have written down all 336 characters.

Step 4: Read the resulting string of 336 characters, which is the decrypted message. 

The final message should be:

"SLOWLYDESPARATLYSLOWLYTHEREMAINSOFPASSAGEDEBRISTHATENCUMBEREDTHELOWERPARTOFTHEDOORWAYWASREMOVEDWITHTREMBLINGHANDSIMADEATINYBREACHINTHEUPPERLEFTHANDCORNERANDTHENWIDENINGTHEHOLEALITTLEIINSERTEDTHECANDLEANDPEEREDINTHEHOTAIRESCAPINGFROMTHECHAMBERCAUSEDTHEFLAMETOFLICKERBUTPRESENTLYDETAILSOFTHEROOMWITHINEMERGEDFROMTHEMISTXCANYOUSEEANYTHINGQX"

That's it!

Verify With: Skip Cipher: Decode/Encode 

Note: This Method Uses The Skip Decoder To Decrypt.

Key: None

Method: Shift & Skip Cipher (Encode)

Shift: 192

Skip: 192

Step 1: Start with the original cipher string:

"ENDYAHROHNLSRHEOCPTEOIBIDYSHNAIACHTNREYULDSLLSLLNOHSNOSMRWXMNETPRNGATIHNRARPESLNNELEBLPIIACAEWMTWNDITEENRAHCTENEUDRETNHAEOETFOLSEDTIWENHAEIOYTEYQHEENCTAYCREIFTBRSPAMHHEWENATAMATEGYEERLBTEEFOASFIOTUETUAEOTOARMAEERTNRTIBSEDDNIAAHTTMSTEWPIEROAGRIEWFEBAECTDDHILCEIHSITEGOEAOSDDRYDLORITRKLMLEHAGTDHARDPNEOHMGFMFEUHEECDMRIPFEIMEHNLSSTTRTVDOHWX"

Step 2: Encode

Starting from the 192nd character of the new string, write down every 192nd character until you reach the end of the new string. Then, starting from the first character of the original string, write down every 192nd character until you have written down all 336 characters.

Step 3: Read the resulting string of 336 characters, which is the Encrypted message. 

The final message should be:

"THECANDLEANDPEEREDINTHEHOTAIRESCAPINGFROMTHECHAMBERCAUSEDTHEFLAMETOFLICKERBUTPRESENTLYDETAILSOFTHEROOMWITHINEMERGEDFROMTHEMISTXCANYOUSEEANYTHINGQX? - Top

Step 4: Shift The Results

Next You Have To Shift The Entire Message 192 Spaces To Create The Plaintext Solution:

"SLOWLYDESPARATLYSLOWLYTHEREMAINSOFPASSAGEDEBRISTHATENCUMBEREDTHELOWERPARTOFTHEDOORWAYWASREMOVEDWITHTREMBLINGHANDSIMADEATINYBREACHINTHEUPPERLEFTHANDCORNERANDTHENWIDENINGTHEHOLEALITTLEIINSERTED - Top

Bottom -  THECANDLEANDPEEREDINTHEHOTAIRESCAPINGFROMTHECHAMBERCAUSEDTHEFLAMETOFLICKERBUTPRESENTLYDETAILSOFTHEROOMWITHINEMERGEDFROMTHEMISTXCANYOUSEEANYTHINGQX"

step 5: Clean It Up

"SLOWLYDESPARATLYSLOWLYTHEREMAINSOFPASSAGEDEBRISTHATENCUMBEREDTHELOWERPARTOFTHEDOORWAYWASREMOVEDWITHTREMBLINGHANDSIMADEATINYBREACHINTHEUPPERLEFTHANDCORNERANDTHENWIDENINGTHEHOLEALITTLEIINSERTEDTHECANDLEANDPEEREDINTHEHOTAIRESCAPINGFROMTHECHAMBERCAUSEDTHEFLAMETOFLICKERBUTPRESENTLYDETAILSOFTHEROOMWITHINEMERGEDFROMTHEMISTXCANYOUSEEANYTHINGQX"

That's it! 

Verify With: Skip Cipher: Decode/Encode 

Note: This Method Uses The Skip Encoder To Encrypt.

This Is A Long And Convoluted Method That Uses A1Z26, Columnar Transposition, Keyed Route Transposition & Is What Has Been Offered As The Solution By The NSA, CIA & Shills Since 1990. The Methods They Used Are Faked Because Jim Literally Just Gave Them Solutions. Hence Why Nobody Can Clearly Solve Using This Method.

For The Record:

KRYPTOS = 0362514 - A1Z26 Cipher Starting At "0"

Or...

Kryptos = 1473625 - A1Z26 Cipher Starting At "1"

Note, To Do The NSA Method, You Must Split The Cipher Into Groups Of 7, Transposition Route With One Of The Mentioned Routes, Grid It Again In A New Grid Size, Then It Can Be Read Out Reading Down The Columns & From Right To Left.

Another Thing To Note, The Original Handwritten Notes By Sanborn Show He Folded The Paper At 2 Locations By The Fold Marks And Staple Holes Along With Notes And An Arrow (Supposed To Reference "Layer 2", Which Was Part Of Another Solution That Sanborn Messed Up By Removing A Vital Character In The Cipher "s" Which Incorrectly Decoded To "Rows By ID"). Given The Overall Lack Of Trust Of Sanborn (I Used To Be One) & Knowing Nothing The NSA Says Public Will Be Said At Face Value & They Lie Religiously. 

30 Years & So Many Errors, This Is Just Like Cicada3301 & How Bad Actors & Prophets For Profit Ruined A Fun Puzzle & Movement. 

Anyway, Ranting Is Over...

A Simplified Variation With A Single Route Transposition & No Key Is All You Really Need. 

K3 Can Be Solved On Paper In A Grid That Is 48 Columns & 7 Rows.

Method:

Take The Cipher, Grid It Out, Starting At Row 4, Column 48 "S".

Read down the columns skipping 4 rows (Wrapping To The Top Row If Needed).

Then Move 1 row Left & Repeat The Pattern. That's It!

I Will Update This Later. Noticing So Many Fake Solutions That Make This Seem Harder Than It Really Is.

K4 Is Most Likely Messed Up & Contain Errors. Jim Was An Artist, Not A Cryptographer. Also, Jim Sanborn Isn't Even His Real Name.
