Crypto Cache # 10 - ENIGMAType: Mystery | Size: Regular 
| Difficulty: 
| Terrain: By: ColoradoPaul @ | Hide Date: 09/05/2008 | Status: Available Country: United States | State: Colorado Coordinates: N38° 42.546 W104° 56.711 | Last updated: 06/19/2022 | Fav points: 0 The above coordinates are NOT the location of the cache. To find the cache, solve the following intercepted German Enigma cipher. But first, you must find five other caches (GC1FWA2, GC1FWAH, GC1FWAZ, GC1FWBB, GC1FWC9) in no particular order to collect and assemble components for your Enigma machine and to obtain necessary code settings. KTCLJ IMRXH AMFET NFIZE NTPWN VDQNH HMQDD IZHWA PTDPT XRGBG CFHQQ AJUHP TPL You are of course welcome to try solving the above cipher using none or only some of the components! The Enigma machine was the primary German encryption method used during World War II. Invented by the German Arthur Scherbius, it consists of five basic components: a keyboard for entering letters, a plugboard, a number of scrambling units called scramblers or rotors, a reflector and finally a display board for indicating the corresponding encoded or decoded letters. Basically how Enigma works is as follows. First, a letter to be enciphered (plaintext) was entered on the keyboard. Then it would pass through the plugboard which allowed specified letters of the alphabets to be swapped in pairs. The electrical impulse or letter would then pass through a series of scramblers (usually three) each with a unique internal wiring pattern such that a letter entering in one position would emerge at a different position. Finally the letter or electrical impulse would contact the reflector which would again alter the position of the letter and ‘reflect’ it back through the scramblers and plugboard in the reverse direction where it would light up a letter (ciphertext) on the display board. Each scrambler would rotate after varying numbers of letters had been entered, hence altering the encryption after each letter. The total number of individual ciphers possible with all the variables exceeds 10,000,000,000,000,000. Each component of the Enigma machine is discussed in more detail on the face sheet for one of the five geocaches listed above. So once you have read and obtained all necessary information, you are ready to solve the cipher. First, note that with all the components of the Enigma machine in the correct starting position used to encrypt a message (the scramblers placed in the correct order, with the correct original scrambler starting positions and with correct plugboard swaps), a message is deciphered by simply typing in the ciphertext letters on the keyboard. The machine works in reverse to decrypt the message. Rather than using three-dimensional wheels for the parts, it is easier to use two-dimensional vertical linear representations of the keyboard, the plugboard, the scramblers, and the reflector. For example, after each time a letter is encrypted, the first scrambler rotates by one space such that the next letter of the alphabet is in the top position on the first scrambler. In terms of a two-dimensional diagram and for this geocache Enigma, the wiring sequence of the first scrambler shifts UP one space. To solve this cipher, assume the vertical electrical order of letters on our keyboard as A, B, C…Z. Then make any plugboard swappings. For example, if C and G are swapped on the plugboard, when C is typed in, it goes to the G location, and G goes to C (see diagram), Or you could just change the vertical order for the wiring on your keyboard to A, B, G, D, E, F, C…Z. Orient the correct scrambler in the first position alongside the keyboard with the prescribed starting letter of the first position scrambler alongside the A position of the keyboard. Align the second position scrambler alongside the first position scrambler, again making sure to align the correct prescribed starting letter of the second position scrambler so it also is in line with the A position on the keyboard. Align the third position scrambler. Finally, align the reflector alongside the third position scrambler. The reflector doesn’t rotate, hence the top of the reflector remains in line with the A position on the keyboard regardless of any rotations of the scramblers. For purposes of this geocache Enigma machine, the scramblers will rotate AFTER a letter is entered. Make a note when each scrambler will rotate. Remember, the first position scrambler will rotate one position after each letter is entered. The other two scramblers in the second and third position remain stationary until a set point comes for them to rotate. If the first position scrambler is set, for example, to cause the second position scrambler to rotate when the first position scrambler is at the ‘Q’ position, then if it is in the ‘Q’ position, the next time the first position scrambler rotates from Q to R in this example, the second position scrambler will also rotate one position in alphabetical order and one position up in the electrical wiring. Similarly, if the second position scrambler is set at, let’s say ‘C’, to cause the third position scrambler to rotate, and the second position scrambler is at ‘C’, then the next time the second position scrambler rotates, it will cause the third position scrambler to also rotate up in wiring. This will be a point when all three scramblers rotate one position. Type in the first letter of the code and follow it through the plugboard, scramblers and reflector and then back through the scramblers and plugboard to the keyboard which is wired the same as the display board. Then rotate the scramblers as described and continue with the next letters. (see enigma example picture in gallery below) To somewhat simplify the operation of your Enigma machine for this cache, two components of the real scramblers (the core and the alphabet ring that rotated in relationship to the core) have been combined, and the process of “double-stepping” has been eliminated. Finally, no discussion of Enigma would be complete without recognition of the genius of two men whose efforts in particular were responsible for the cracking of Enigma during World War II, Marian Rejewski in Poland and Alan Turing at Bletchley Park in England.

1) Viel erfolg! (I wish you success!) 2) The coordinates at the top of the page are a key waypoint where a trail heads upward. Suggest you follow this trail all the way to the saddle and meadows and then head up ridge toward cache. Ammo can between two small pine trees (one dead).
