Three codes were hidden in the HTML source of the TYCHO’S SECRET post on the Investigate Ingress blog.

[1] 15243454421524351142114324441511445214432443

[3] \\\\\\\\\\.\\\\\\/./\\//.//.\\\\\\//.//\\\\.////\\.\\\\/\\.//\\\\\\.\\\\\\

Code #1

Observations

There is a specific cipher that uses that range of numbers

Code #2

Observations

The code is only missing the keyword and there is a good hint that points to it

Code #3

Observations

You have three different characters. One is obviously a split so you need a cipher that uses 2 bits.
