There were 3 codes in the Stockpiles post on the Investigation Blog.

`[1 (line 288)] aa98998fa87b8d968898ad76aa87`

[2 (line 291)] ttyouuyyteyiiwyoytuuiptwiettir

[3 (line 306)] jdnjoruulruonxubsdtgmkvfu0jnuyl0t1

# Code #1

## Observations

At first glance, the code looks like a hexadecimal encoding, pairing up the digits:

`aa 98 99 8f a8 7b 8d 96 88 98 ad 76 aa 87`

However, it falls outside the range for the hexadecimal characters 0-9, A-Z or a-z, so there is more work to do with the code.

In the ASCII system, numbers (`30`

–`39`

) have a lower value than letters (`41`

–`5a`

, `61`

–`7a`

). Looking at the code we have, the values we have in the number positions (`aa, a8, ad`

) are larger than all the other values.

If only there was a cipher that reverses the order…

# Code #2

## Observations

The letter distribution reveals an interesting subset of the alphabet:

`EIOPRTUWY`

Maybe not too interesting, however, if you change the order of them:

`WERTYUIOP`

[hint]

Maybe look down on your keyboard?

# Code #3

## Observations

The distribution of the letters seems slightly mixed up, but looking at letter pairs could reveal a pattern hidden in the code:

`jd nj or uu lr uo nx ub sd tg mk vf u0 jn uy l0 t1`

Just looking at the number positions (first, fifth, fourth last, second last) for now:

`jd lr jn l0`

If we assuming the code is either in hexadecimal or decimal, the `J`

and `L`

values should be `3`

or `5`

respectively.

There’s also values of `0`

and `1`

we need to deal with…
