Kleopatra fails to create new Key Pair
Open, NormalPublic

Description

Kleopatra does not create a key pair.
OS: Windows 10 Home, Version 1803

Bug occurs when pressing File -> New Key Pair -> Creating a personal OpenPGP key pair.

After entering a name, email and passphrase a menu appears stating

"Key Pair Successfully Created" with the Fingerprint and the options to Backup the Key Pair, send the public key per email and to upload it to directory service.

Until here everything is working correctly.

But after pressing "Finish", no new key-pair appears, as i was not doing anything at all and doesn't show my new key-pair.

When I try to backup the key pair in the end of the setup and safe it, it shows an error message:

"An error occurred while trying to export the secret key.
The output from C:\Program Files (x86)\GnuPG\bin\gpgsm.exe was: gpgsm: key '' not found: Invalid User-ID"


I tried instaling different GPG4Win versions but the problem stayed.

Thank's in advance!

Thank you for your detailed report. Seems like something strange is broken on your system and our error handling does not properly cover that.

Can you please open the command line (cmd.exe) and check there with
"gpg -K" if the key was created?

Or if there are any errors from this output.

Afterwards can you do:

"gpg --gen-key" and follow the instructions on the screen to create a key from the command line.

It's probably easiest if you copy & paste the output from that here so that we can take a look if we see any unusual messages.

Thanks in advance!

So these are the results for gpg -K:

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

Thanks!

gpg: keydb_search failed: Provided object is too short

This is the underlying cause. The internal storage of gnupg is corrupted.

As a workaround you can rename the folder "%APPDATA%\gnupg" to something line %APPDATA%\gnupg-old
Then it should work. (%APPDATA% expands to something like c:\users\your_user_name\appdata\roaming\ )

We do not have a known issue though how this could happen. So I will keep this as a bug.

@werner Do you have any idea how this can happen?
