I succeed to encrypt & verify my complete “Documents” directory
(~3.8 Go) but when I want to decrypt & verify it, Kleopatra aborts &
nothing is untared in expected directory.
deriving from your post, is the following correct:
You are using gpg4win 2.3.2
After encrypting and signing you end up with a ~3.8 Gigabyte encrypted tar file?
decryption with kleopatra fails, though you get a password entry.
What is the precide message kleopatra gets you? No message?
If this is the case, I think the next diagnostic step would be to try to
decrypt the file on the command line to see more messages.
Could you try a
gpg2 -v --decrypt path-to/yourfile
next?
