What was the command line you used to invoke gpg? It looks like it is
expecting you to type in an OpenPGP message, i.e., one that begins with
"-----BEGIN PGP MESSAGE-----" for example. "test" is not valid OpenPGP
data. I think you made a mistake in the invocation.

A test for encrypting and decrypting stuff from the command line looks
something like this:

$ echo Hello >test.txt
$ gpg -r stefan.boehringer at posteo.de -e test.txt
$ rm test.txt
$ gpg test.txt.gpg

And at the end, you'll have your test.txt back. If (like me) you think
pipes are cool, try this:

$ echo Hello | gpg -r stefan.boehringer at posteo.de -e | gpg

HTH,

Peter.
