This raises a question I haven't encountered before: for many purposes for which encryption is used, the very existence of the document might be what you're trying to keep private. So is there a common encryption format that doesn't make it obvious that the file is encrypted?
I guess that wouldn't be enough. A carefully preserved file of random data with no header at all would obviously be something encrypted. You'd probably have to go full steganography and make the file appear to be something else (like a telescope image).
