Halo Terminal Secret codes revealed?

The Input Device

The Halo Terminal Codes cracked?

"This is the input device. The input device grants access to the Terminals when a correct code is entered. The input device allows codes to be 1 to 10 characters long. We know 10 codes which are each 5 characters long and were found at the end each one of the Terminals. Entering all of them successfully granted access to a secret 11th Terminal. This proves that there is a possibility of additional Terminals."
