Topic: Decrypting outside of GMail

So I sent an email with GMail to a friend of mine who doesn't use GMail.  How can he decrypt/verify my email?  This question entails all (decrypt & verify), verify, and/or decrypt.

(Decrypt & Verify) & Decrypt
=================

There is an attachment called noname.  Selecting the PGP block and running it through GPG yields nothing.  I've tried it myself like this.

$ gpg -d
<Paste PGP block>
Prompt for passphrase: <passphrase>

GPG then shows me a list of keys it was encrypted with, but doesn't display the message.


Verify
====

How can you verify the email when the signature is in an attachment?


I know some of these questions might be related to my lack of gpg-fu, but I've spent a good amount of time reading the man page and nothing seems to help.

TIA

Re: Decrypting outside of GMail

So the encrypted/signed content of a GMail message from FireGPG is only decryptable/verifiable via FireGPG?

Re: Decrypting outside of GMail

No, you can use enigmail or any program who support openpgp/mime (there are many), but there is only FireGPG for Firefox.

Re: Decrypting outside of GMail

Alright, so how do I decrypt it by hand via GPG?  All attempts to decrypt/verify emails sent from GMail using FireGPG have failed.  Even if the mail is sent to another GMail account, without FireGPG and only gpg, I haven't figured out how to decrypt/verify it.  In the context of just verifying an email, looking at the original message has proved useless.  I see the base64 encoded message.  I've decoded it, but the signature doesn't match the content, according to command-line gpg.
