Not to sure how to explain this one but there is a total of 152 bits. I first made groups of 8
21071211 17211707 17211211 17201211 17201806 21071720 21071721 21071712 17212107 21071707 17071712 17071721 21071211 17071712 17201720 17202107 17201120 21071120 17211707
Let’s group them by the passcode format

We are looking for a 9 letter keyword with repeating letters at the 6th and 9th position
Using the regex expression ^…..(.)..\1$ to search the keyword list, the only possible result is KNOWLEDGE
We can now build the index using the Ascii values and assuming that the numbers are grouped in 4
