KDE Wallet with GPG encryption
Setting up KDE Wallet with GPG encryption
The first time an application tries to access your KDE Wallet, if it doesn’t exist, the following windows will pop up.
If you click next and don’t find your GPG key that can be because it’s level of trust is insufficient. To fix this follow these steps.
1. Find the uid of the key you want to edit:
Type gpg --list-keys to see your available keys and get it’s uid
➜ ~ gpg --list-keys
/home/alejandro/.gnupg/pubring.kbx
----------------------------------
pub rsa4096 2021-06-16 [SC] [expires: 2024-06-15]
3E6C08BFBF1EAC1E8CDCCC2555DFFFC61C31
uid [ultimate] Alejandro Criado-Pérez <alejandro@criadoperez.co>
sub rsa4096 2021-06-16 [E] [expires: 2024-06-15]
In this example the uid is Alejandro Criado-Pérez
If you don’t have any keys listed you will have to import one (gpg --import mykey.asc) or create one first.
2. Edit the trust level of the key with the command gpg --edit-key uid
➜ ~ gpg --edit-key 'Alejandro Criado-Pérez'
