# gpg-switch-yubikey

Switch GPG between two YubiKeys that hold identical key material.

GPG binds secret key stubs to a specific card serial number. When you swap YubiKeys, GPG prompts you to insert the other one. This script deletes the stubs and re-learns whichever card is currently inserted.

## Install

```bash
cp gpg-switch-yubikey ~/.local/bin/
chmod +x ~/.local/bin/gpg-switch-yubikey
```

Make sure `~/.local/bin` is in your `PATH`.

## Usage

After physically swapping to a different YubiKey:

```bash
gpg-switch-yubikey
```

## Configuration

The script contains a hardcoded GPG key fingerprint. Edit the `FINGERPRINT` variable in the script to match your own key.
