This implies that we need to decode the text to the right (part 2) with Vigenere, key ZIGNZAG.
ZIGNZAG is also a hint to how the text should be read in part 2 - zigzaggingly.
Method: Vigenere with the key ZIGNZAG
The original text can be extracted if read zigzaggingly:
And after formatting:
Between the encrypted texts lies the final secret of Kryptos. It has remained a mystery for decades.
How is that possible? I can not answer, for I am not Jim.
Some speculate he may had[have] used magical squares in the encryption. If I were him I would've gone with the martian flavor.
Do not get fooled by the iqlusion[sic] of indecipherableness, it will one day be finally decrypted and the community would rejoice.
Should you decide to give it a try, make sure you play fair and not cheat in anyway, as the fun is lost th[e] moment you choose to break the rules.
Look southwest if you were lost in the gigantic wall of texts. More is to be found.
- Magical Squares - Magic squares, "Martian flavor" refers to the Mars magic square.
- Highlighted P - Playfair cipher
- Look southwest - Location of the next part (part 3)
Method: Playfair cipher with a table based on the Mars magic square (A1Z26)
The text contains 25 letters that are not a part of any words.
In order of appearance they are: XJRNCIWOMFLVEPHTBADGKSUYQ
After formatting and removing the extra letters, the text reads:
Within the four parts of this riddle are hidden secrets that have to be used together to decipher the final message. If you have trouble finding one of them, refer to chapter one, line fourteen.
To the east is a hill, in front of which is a sign, on it are the words "Chef Gabid". On the hill is an Actec[Aztec] style pyramid that is said to contain a secret within. And to the right is the final message.
Nobody knows how to get the secret out of the pyramid, although it is believed that primes are involved.
As for what the final message is about... It is up to you to crack the cipher and reveal its hidden secret.
For part 4:
For part 5:
- Highlighted H - Hill cipher
- Highlighted A - Aztec code.
- Chef Gabid - This is not a real name, but rather the matrix to use for hill cipher, as hinted by "the sign in front of the hill"
- Primes - How to convert the letters to Aztec code
- To the east - Location of the next part (part 4), although this is already deducible from the fact that there is only one part left
- Hidden secrets - Each part of the puzzle contains one set of 25 non-repeating letters that are used in part 5
- Chapter 1 Line 14 - The set of letters to use for part 1
4-1: Hill cipher
Method: Hill cipher with a matrix based on the phrase "Chef Gabid" (A1Z26)
According to the text in part 3, this part consists of an "Aztec pyramid" and a "final message". The X's in the decrypted text acts as a border that separates the two sections.
|4-2: Aztec Pyramid
Method: Converting letters to 0/1 based on their A1Z26 value
Part 3 mentions that primes are involved, so group the letters into primes and non-primes based on A1Z26 values, then convert the result to a scannable Aztec code.
Prime letters: BCEGKMQSW
Non-prime letters: ADFHIJLNOPRTUVXYZ
When scanned, it gives the string MTKHVADQBGOCUYNIPWSEXJLRF.
Method: Four square cipher with the table
|Each part of the puzzle contains one string that is used in the table:
Part 1: Line 14 GHIJLMNQUVWXKRYPTOSABCDEF
Part 2: Mars magic square KXGTCDLYHPQEMUIJRANVWFSBO
Part 3: Leftover letters XJRNCIWOMFLVEPHTBADGKSUYQ
Part 4: Aztec code result MTKHVADQBGOCUYNIPWSEXJLRF
After formatting: (the last 2 letters are padding, thus not needed)
If WW knows what was hidden in Kryptos, did he tell the secret to the next director?
Whom would he have told if he really did?
WW refers to William H. Webster, then Director of CIA when Kryptos was completed.
Whether or not he knows the solution to Kryptos is debated, but his name was referred to in passage 2 of Kryptos. ("Who knows the exact location? Only WW.")
To answer this question, we need to find the next Director of CIA after William Webster (since Kryptos is located in the CIA).
The next Director of CIA after William Webster is Robert Gates, and thus the solution to the weekly is:
Egg 1: Family Guy funny moments|
In part 4, after the first decrpytion, the phrase "Family Guy funny moments" can be spotted at the bottom of the Aztec code section.
Changing the url to familyguyfunnymoments.html gives the egg.
Egg 2: hill.flv (not implemented)
This egg wasn't implemented due to file upload restrictions on NeoCities.
In part 3 on line 10 the word "hill flv" can be found.
However since free accounts can't upload videos on NeoCities, this egg was not added to the puzzle.
