gpg -sign problem

Peter_Haufschild · August 12, 2014, 12:33pm

Hello,
I could encrypt and decrypt an email successful.
But I have Problems with the test of the signature.
When I try

gpg --verify signature.asc
gpg: no signed data
gpg: can't hash datafile: No data

or I save the Massage in Outlook and the signature and try to verify both with cleopatra.

What's my mistake?

Could it related to some later happend changes in the mail headers? I do amavis dkim and so on after chiphermail for outgoing mails.

Hello,
I could encrypt and decrypt an email successful.
But I have Problems with the test of the signature.
When I try

gpg --verify signature.asc
gpg: no signed data
gpg: can't hash datafile: No data

You cannot directly use gpg to verify a PGP/MIME signed email. You need
to split the message part and the signature part into separate files and
then validate. The problem is that it is easy to make a minor mistake,
for example add an extra newline, which will result in a broken
signature. It's much easier to open the eml with a tool that can
validate a signature (for example Thunderbird)

Kind regards,

Martijn Brinkers
