Konoha Cryptanalysis Team

The Konoha Cryptology Squad is an office specializing in deciphering secret codes and messages. They appear to take direct orders from the Hokage. Their base of operation is located in a library-structured office. This facility posesses a desktop computer and numerous vertical files, presumably holding almost all of the secret codes Konohagakure uses in missions and message delivery.

Invasion of Pain arc
The Konoha Cryptology Squad was requested to assist in deciphering the code Jiraiya left behind. After finding out the key to the code (with help from Naruto and Kakashi), they get the text "The real one isn't among them", refering to who the real Pain is.
