Yeah, not my point. I was basically saying that you can't tell by
merely looking at cyphertext what algorithm was used to encrypt, as it
is random, which is indeed the point of encryption. If someone (vendor)
wanted to slap a little header on an encrypted file (or wrap it around
said file), more power to them.

Sorry for the ambiguity, I forgot how much people assume everyone's a
moron (except themselves) on here.

If you had quoted the context, you would have been reminded that the
question was:

>>If I have a file with an .enc extension is there any way that I can
>>tell what type of encryption, AES or Blowfish, was used?

which is a *file* level question, not a payload-level question. And
in terms of *files* we cannot answer it because the ".enc" extension is
not sufficient for us to pin down the originating program.

Is that from the same author who recently wrote,
Wow, that was an undetailed reply. You expect someone asking
that question to know what to do with this answer?
?
