Looks like Hex, but wrong way around when looking at the ranged for the passcode format.
When we have numbers higher than letters, we have one cipher that can remedy that!
Pair up the original string for easier handling
a9 87 7e 76 ad 9a 7c 7b 96 7d 8c 86 87 a8 6f aa 6f
Using a special version of Atbash for Hex values (
FEDCBA9876543210), we get values that are much better for our ranges
56 78 81 89 52 65 83 84 69 82 73 79 78 57 90 55 90
Converting this from decimal to ASCII we get the following string
Now we know Asterion is not a valid KW, so googling it brings us to the first king of Crete, “Asterion” who assumed the form of the Cretan Bull. In Crete, the Minotaur was known by its proper name Asterion.
In this instance, we will sub
Minotaur in, but keep the last letter of the original code (
This brings us to the final solution. But fear not, this is not the last strange keyword sub for today!
Looks like everything is there, so maybe just a simple substitution.
Google will be needed, but look a step up and search for a bit more than just the normal.
Taking the obvious first step, let us reverse the code
Googling for the entire middle part between the numbers (
mork) you should find the sitcom Mork & Mindy.
Mind is a valid keyword and since we used the
k for our googling, let us use the
y from Mindy.
Subbing all that into our code, we get our final solve! Phew
Take a look at the normal steps, but there is a hidden thingy that needs to be done to get it valid.
It is not just for letters 😉
Looking at one of our first steps for decoding a passcode, we see that with ROT25 gives a valid keyword
But we know that
0 is not a valid number, so another step is needed.
Atbash will not work here since that will affect up our letters also.
Looking back at ROT24, we see that it is the same as ROT-1.
We also know that ROT5 is generally used for numbers, so what if we use a ROT-1 of the numbers version also?
And with that, we have a valid passcode, easy hu? 😛
In cases like these, it is good to know how all the standard cipher can be used differently.
Today we had the special Atbash and the ROT-X for both Numbers and Letters.
