As I understand it encrypted emails have a high profile (detectable through pgp header / attachment).
Would it be possible to match the encrypted data with a wordlist to hide the fact that the email contains a encrypted message?
I know that the other person would need the same list of words for decrypting and the message would be only a bunch of random words, but the fact that its encrypted world be not as obvious for automated scanning.
EDIT: As pointed out I am referring to steganography to hide from traffic analysis.
