Abstract
Encrypted communications is made to appear to be normal text so as to avoid undue attention to either the sender or recipient. Information can be hidden or embedded in innocuous documents using steganography wherein the information is masked within a larger document. Other approaches would translate the ciphertext into a form of normal looking text that would in effect be gibberish but would use normal words in at least one native language. There are many tradeoffs and benefits to be considered when attempting any form of encrypted communications.
