I encrypted a file using symmetric encryption (gpg2 -c file.txt). Then I tried to decrypt it (in Emacs) which opened a pinentry window. I accidentally clicked on the check mark labeled “save in password manager” and clicked “Ok” without having entered the password. Opening the file obviously failed, but when I tried to open the file again, GPG apparently reused the empty password and didn’t give me the chance to enter the correct password. The error message was:
gpg: AES encrypted data gpg: gcry_kdf_derive failed: Invalid data gpg: encrypted with 1 passphrase gpg: decryption failed: No secret key Now I’m stuck with an encrypted file that I can’t decrypt although I have the password. Question: How can I remove the incorrect password and restore the password prompt? I already tried a couple of things: - Kill gpg-agent. - Kill gnome-keyring-daemon. - Remove the stored key using Seahorse (failed because the key wasn’t listed in Seahorse). - Reboot the machine. None of it helped. Feature requests / bug reports: - Pinentry shouldn’t store the password when it’s wrong. - When decryption with a stored key fails, gpg should prompt the user for the correct password. - It should be transparent to the user where keys are stored. Specifically, the label in the pinentry window should be more information, e.g: “Store password in Gnome keyring. Use seahorse to edit or remove.” Titus
