Title: Verifying signature result with Electrum 3.0.5
Post by: Darooghe on January 08, 2018, 08:24:12 PM
I did verifying signature's process with GPG Kleopatra. electrum 3.0.5 verified but GPG said the data could not be verified. Is there any security problem with Electrum 3.0.5?
Please a technical person check it & share results with us.

As I responded to your post in the other thread... this is FINE... it just means that you have not "vouched" or "certified" that ThomasV's key is legit, you can import keys in GPG, but not TRUST them... until you explicitiy trust the key you will see something like:

NOTE: THIS IS A GOOD SIGNATURE! The signature checks out, and the file is signed with the signature... YOU just haven't trusted it yet.


If you "trust" ThomasV... then you can sign the key, saying that you vouch for Thomas and he is legit and all things signed with his key are legit... then you will see something like this:

The important thing is that you DON'T see a red warning like this:

If you see "Invalid Signature" then that is BAD!
