### Export the generated key ### Export the generated key
This one-liner exports your generated key into a new subdirectory "backup": This one-liner exports your generated key into a new subdirectory "kiwi-backup.gnupg":
```sh ```sh
docker run --rm -it -v "gnupg.tmp:/root/.gnupg" -v "$(pwd)/backup:/root/backup" -e "CURRENT_USER=$(id -u):$(id -g)" yavook/kiwi-backup:0.10 sh -c 'cd /root/backup && gpg --export-secret-keys --armor > secret.asc && gpg --export-ownertrust > ownertrust.txt && chown -R "${CURRENT_USER}" .' docker run --rm -it -v "kiwi-backup.gnupg.tmp:/root/.gnupg" -v "$(pwd)/kiwi-backup.gnupg:/root/kiwi-backup.gnupg" -e "CURRENT_USER=$(id -u):$(id -g)" yavook/kiwi-backup:0.10 sh -c 'cd /root/kiwi-backup.gnupg && gpg --export-secret-keys --armor > secret.asc && gpg --export-ownertrust > ownertrust.txt && chown -R "${CURRENT_USER}" .'
``` ```
You'll now find the "backup" subdirectory with files "secret.asc" and "ownertrust.txt" in it. Check your exported files: You'll now find the "kiwi-backup.gnupg" subdirectory with files "secret.asc" and "ownertrust.txt" in it. Check your exported files:

This should output your 16-digit Key-ID, so take note of it if you haven't already! Afterwards, run `docker volume rm gnupg.tmp` to get rid of the key generation volume.
