Encryption code

Encryption Code is placed on UNSC transmissions in order to maintain the level of secrecy demanded by the Transmission Classification. Encryption codes, like classifications, come in varying types, based on the importance of the information in the file. Sometimes an AI will be required in order to decode the data.


 * Encryption Code: NA: Transmissions without code are not classified at all and can be accessed by anyone at any time. Examples of this include the journals produced by UNSC Astrophysics.


 * Encryption Code: Red: This code is used most of the time in military transmissions. Classification can be "Restricted," "Classified," or "Secret". The code is sometimes harder to crack, depending on how complex the scheme of the code can be. Examples of this code include the Cole Protocol.


 * Encryption Code: GAMMA: This is a high level code. It is used on the most classified information and is likely to be an extremely complex code. It coincided with the classification of "Eyes Only Top Secret."
