Look closely at the middle of the string, can you spot the passcode format ?
Looking at the middle of the string you can see 5kce5n9g4u which could point to the prefix and suffix but then the rest doesn’t really look good.
There are 18 characters, try reversing the first and last groups of 9 characters
We now have the right code format but need to find the right keyword substitution.
Searching on Wikipedia we see a reference to a mountain called “Le Môle” that rises 1,863 meters. Mole is a valid keyword
Multiple pairs of letters and numbers but there is enough in there to guide you through what you need to search
Separate letters and numbers
Seems like we have a phrase written in reverse
tear one off and scratch my head what was once red is black instead
Remember The Riddler in Batman ? His original name was Edward Nygma or E. Nygma. Enigma is a known keyword. Let’s keep that aside for now.
Let’s do the same reverse trick to the numbers and make pairs
88 74 87 74 79 75 74 86 68 75 82 79 89 69 85 75 85 71 76 71 67 90 84 82 73 82 82
Good number distribution for Ascii. Convert decimal to Ascii
Not much, even ROT and Atbash don’t give anything. Now remember that we have the keyword which could serve as a key for Vigenere:
Well 54 could mean 6 in Ascii but in this case it’s simple (or not so evident) Niantic math. 5+4=9
All that is left to do is to insert the enigma keyword
Why would there be / in a code ? A glyph? Or maybe a it gives away the cipher
This type of cipher was used in a few consecutive posts in the past. The / gives it away as being a keyboard mirror cipher. At one point you’ll also remember some key elements of ciphers like in this case, YOW=TWO.
