To set up a GPG key for use with KDE Wallet in Visual Studio Code, follow these steps:

1. Install GPG

Ensure gpg is installed on your system:

sudo apt install gnupg  # Debian/Ubuntu
sudo pacman -S gnupg    # Arch
sudo dnf install gnupg  # Fedora

2. Generate a GPG Key

Run the following command and follow the prompts:

gpg --full-generate-key

• Key Type: Choose RSA (default).
• Key Size: 3072 or 4096 bits.
• Expiration: Set as desired (e.g., 0 for no expiration).
• Name/Email: Use details tied to your KDE account.

3. List Your GPG Key

Note the Key ID (e.g., ABC123DEF456):

gpg --list-secret-keys --keyid-format LONG

Output:

sec   rsa3072/ABC123DEF456 2023-01-01 [SC]
      A1B2C3D4E5F6G7H8I9J0K1L2M3N4O5P6Q7R8S9

4. Configure KDE Wallet to Use GPG

1. Open KDE System Settings.
2. Go to KDE Wallet > Wallet Preferences.
3. Click Change Wallet Encryption.
4. Select GPG and choose the key you generated.
5. Confirm and close the settings.

5. Set Up VS Code/Git Integration

Configure Git to use KDE Wallet as the credential helper:

git config --global credential.helper /usr/lib/git-core/git-credential-libsecret

• If the path differs, adjust it (e.g., /usr/bin/git-credential-libsecret).

6. Verify Functionality

• Open VS Code and perform an action requiring credentials (e.g., Git push).
• KDE Wallet should prompt you to store the password, encrypted with your GPG key.

Troubleshooting

• Passphrase Prompts: Ensure gpg-agent is running to cache your GPG passphrase.
• Default Wallet: Set your KDE Wallet as the default in Wallet Preferences.

This setup ensures credentials used in VS Code are stored securely in KDE Wallet via GPG encryption.
