Inside the Portal Clue post “The Circular“, on the Investigate Ingress blog, there where three clues hidden inside the source:

`[1] conogacedtcotcoenilnogatednepnogacedaennenogacedisocinogacedtnepnogidiakcedaennenoganogatpehnogaenneelgnairtsocinogacedatetnogidiakinogacediakar`

`[2] emrwbhatmngkrylvcmwu`

`[3] fsofznsfnefsfeesfsfeoetfzssensffioeiieeeiwiniiiieiioiiiiiiieinii`

# Code #1

## Observations

One very long string, but looks like there are some things repeating themselves.

We will need to divide the string a bit and see what it reveals.

Hint

After splitting, counting the edges might help you further.

Solution

Seeing the words `octagon`

, `triangle`

and `line`

in the text, we could assume that geometric shapes are being references here.

Divide the text up into meaningful geometric shape names.

`octdecagon octagon line octdecagon pendedecagon enneadecagon icosikaidigon pentagon enneadecagon heptagon triangle enneadecagon icosikaidigon tetrakaidecagon`

With the help of Google and Wikipedia, we find this list of polygons.

Replace each polygon with it’s value in the table, except for `line`

, it has 2 “edges”.

`18 8 2 18 15 19 22 5 19 7 3 19 22 14`

Using the alphabet index of a=0..z=26, we get our pre-/suffixes

`SICSPTWFTHDTWO`

`6CSP2 F3D2O`

When a code is missing it’s keyword, it generally is the name of either the process or the subject of the substitution.

In this case, we were working with *shapes* and `shape`

is a known keyword. Subbing that in reveals our full passcode:

`6CSP2shapeF3D2O`

# Code #2

## Observations

Only letters in the code, so assume that the numbers will be written out.

The normal ROT/Atbash/Rectangle/Skip doesn’t give any results.

Hint

When the normal results give nothing, take the next step of “try these automatically first” ciphers.

Solution

Using the Autokey Vig cipher with a passphrase of `a`

, we get almost finished result:

`eijnothmantrayniuseq`

Switch out the numbers for our final solve

`8jno3mantray9u7q`

# Code #3

## Observations

Here we have a string that has a few letters repeating at the start and others repeating at the end.

Those infront are not all repeated in the second part, hinting at a two sectional code.

We can also semi see very familiar pairs.

Hint

What happens when you cut in half and fold over?

Solution

Make two lines of the entire string

`fsofznsfnefsfeesfsfeoetfzssensff`

ioeiieeeiwiniiiieiioiiiiiiieinii

Reverse only the second line to reveal two letter numbers!

`fsofznsfnefsfeesfsfeoetfzssensff`

iinieiiiiiiioiieiiiiniwieeeiieoi

Reading each columns, write down the numbers.

`56150965985648875658182506789745`

Making pairs of this shows us that they are not suitable for decimal/hex to text conversion.

But since we already had one reverse in this code today, we see that reversing the numbers gives us the ranges we need.

`54798770528185657884658956905165`

Pair them up

`54 79 87 70 52 81 85 65 78 84 65 89 56 90 51 65`

and finally convert from decimal to text for the final solution

`6OWF4QUANTAY8Z3A`

In addition to the three codes hidden in this post, we also had a Portal clue.

Both factions will always try and figure out what Portal is referred to by such posts and try to get to it first.

Can you determine which Portal this clue is referring to? You will need everything in the post (and subsequent hints posted later) to find this Portal.
