Most often encrypted archives contain more than one file, so the only way this could be true is if there is an archive inside an archive. Which is totally possible.. but then the whole point of a hash is to let someone know that a file is as it was intended. So, if you're not giving a hash for the file you're sending.. you're basically setting people up for opening potentially malicious files on the hopes that the file they want is actually inside. Which to me is just ridiculous.
