If you mean, "a reliable way to tell that something is not an OpenPGP-encrypted file," then yes: check the OpenPGP header at the beginning of the message. If you mean, "a reliable way to tell that something is not an encrypted file, period," then no, not really. There are a lot of qualifiers on the "no, not really." A lot of Ph.D. theses have been written on this subject: it ties into some really deep areas of theoretical computer science. If you want to learn more about the qualifiers, I'd suggest reading up on algorithmic randomness and Kolmogorov-Chaitin complexity. It won't be easy reading, but speaking personally, I find this stuff fascinating. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
