Ah sorry ... forgot to say. I'm running Windows 7. Final version. Got it through my MSDN subscription.

Using version 3.5.2 of Firefox.

Cool ... how could you spot that?

Firefox is set to use UTF-8 and gmail "Use default text encoding for outgoing messages"  is set to "Use default text encoding for outgoing messages"

Should I change that to UTF-8 as well  ??  Or change the firefox setting?

First ... what you asked for:

Output of a clearsign (with the strong DSA/ELG). I used old gmail and clearsign button, to clearsign the message:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

test af clearsign with STRONG cert
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v2.0.12 (MingW32)

=9F/s
-----END PGP SIGNATURE-----

- The FireGPG texteditor is able to verify it just fine,

- But if I mark and and select "verify" from the FireGPG menu I get the following error:
"This message cannot be verified"


Now - if I instead select the same text, and use the "clearsign" command from the dropdown menu, I get this:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

stærk cert
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v2.0.12 (MingW32)

-----END PGP SIGNATURE-----

An I am able to verify that signature, from BOTH the dropdown "verify" and the Textbox verify button.

Do you understand what I mean?  It's more than you asked for, but I thought that might help.
I haven't tried clearsigning untill now, but saw the behavior after a little testing. Again - It's repreducable on my machine.

I've tried to use the correct terms, but are new to the app, so I hope I got the message through  smile

Hi,

I have installed GPG4Win 2.0, and I am using FireGPG for my gmail account. I do not use inline.

I created a certificate using Kleopatra and through the advanced setting I set the keys to be stronger, than the standard 1024 bit for both DSA and ELG-E.

I can not get signature verification to work with the certificate. I've tried deleting and creating a new one - same problem over again.

Signing and encryption and decryption goes well ...  signature verification gives this results:

When certifying the signature I get "Unknown error, FireGPG can't verify this email"

I have no problem getting it to work with with a cert. with DSA/ELG cert 1024 bit keys.  And a 4096 bit strong RSA key works fine as well.

The GPG4Win and FireGPG are default installations. Only thing I've changed is to get FireGPG to ask me which certificate I want to use.

Is this a known problem?  Or is it something with my machine?
