Is it possible to decide what is a gpg file?

Pierre Moulin's got a whole sheaf of really good steganography papers,
and yet most people I've met who advocate steganography have no idea who
he is.  This is kind of like meeting someone who says they're designing
a cryptosystem, and they've never heard of Claude Shannon or read any of
his papers.

Speaking generally, most people who develop cryptosystems don't bother
to read the crypto literature, and most people who develop
steganosystems don't bother to read the stegano literature.  Kind of
sad, really.

authors or the GnuPG developers.)
