The sender will encrypt a piece and send it to the receiver, and will list both the ''public key'' and ''private key'' of the file. The public key is widely available, and was used to encrypt the file.

*'''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 [[United Nations Space Command Emergency Priority Order 098831A-1|Cole Protocol]]. It was used before or during [[2552]] to encrypt [[UNSC Emergency Priority Order 098831A-1]]. | *'''Red''' - This code is used most of the time in military transmissions.
