[GTALUG] GnuPG Woes...

[Peter King]

I could use some help from people who are more expert at GnuPG than I am, which
is most people.

Using GnuPG 2.0.26 and libcrypt 1.6.2, running under Gentoo with kernel 3.17.4,
all at the command line.

I have a gpg key (since 2004) and it's always worked well for me.  Just today,
though, I tried to use it to decrypt a file I'd successfully decrupted many
times in the past:

  $ gpg -d File_to_Decrypt > decrypted_file

I kept getting a "bad session key" error.  After doing some googling, I eventually 
tried the suggestion to run:

  $  gpgconf --reload

After doing so, however, when I try to decrypt the file as before:

  $ gpg -d File_to_Decrypt > decrypted_file

gpg now asks for the data file, and when I offer File_to_Decrypt, I get back a list
of of signatures, each correctly identified with my DSA key ID (as shown by the
command gpg --listkeys), but each entry is followed by the line "BAD signature 
from <my_ID> [ultimate]" -- which seems like very bad news indeed.

Naturally, the encrypted file is valuable (to me), and I have backup encrypted
copies, but nothing in clear...

Well, the gnupg key hasn't changed since February 2004, and it's worked fine all
the way to at least mid-October 2014, the last time I encrypted/decrypted the
file.  Now I'm more or less clueless.  What should I try next?
