are there any useful macros for this? it seems like it is all
encryption that needs to be decrypted, but yet it isn't. I would like
to see the message you sent in mutt...grrr...i'm behind webmail here
and they are seen as attachments....
I have found these two, thus far...
macro compose \CP "Fgpg --clearsign\ny"
macro compose \CS "Fgpg --clearsing\ny^T^Uapplication/pgp;

I am learning very much by having a pgp enabled client, such as mutt,
but I am still learning. I sat down after I installed gnupg and went
through the entire manual, and that helped explain so much. I found it
much better documented then standard pgp unix released documents. I
could be wrong, but this is what I have found.

Clearsigned documents
A common use of digital signatures is to sign usenet postings or
email messages. In such situations it is undesirable to compress the
document while signing it. The option --clearsign causes the document
to be wrapped in an ASCII-armored signature but otherwise does not
modify the document.
alice% gpg --clearsign doc
You need a passphrase to unlock the secret key for

Detached signatures
A signed document has limited usefulness. Other users must recover the
original document from the signed version, and even with clearsigned
documents, the signed document must be edited to recover the
original. Therefore, there is a third method for signing a document
that creates a detached signature. A detached signature is created
using the --detach-sig option.
alice% gpg --output doc.sig --detach-sig doc
You need a passphrase to unlock the secret key for
user: "Alice (Judge) <alice@cyb.org>"
1024-bit DSA key, ID BB7576AC, created 1999-06-04
Enter passphrase:
Both the document and detached signature are needed to verify the
signature. The --verify option can be to check the signature.
blake% gpg --verify doc.sig doc
gpg: Signature made Fri Jun 4 12:38:46 1999 CDT using DSA key ID BB7576AC

Description
This command signs a message that can be verified to ensure that the
original message has not been changed. Verification of the signed
message is done using the command verify.

I hope those help in some way. and of course, I hope the base URL in
there is even more useful in the future. :-)
Oh, and I'll clearsign this. :-) (My MUA is Mutt, so it's easy.)
