GPG Docker Image (Dockerfile)

USAGE

• Show version

docker run --rm -it vladgh/gpg --version

• List keys

docker run -it -v /path/to/keys/store:/root/.gnupg -e GPG_TTY=/dev/console vladgh/gpg --list-keys

• Encrypt with symmetric cipher only. This command asks for a passphrase.

docker run -it -v $(pwd):/gpg -e GPG_TTY=/dev/console vladgh/gpg --symmetric /gpg/my_file

• Generate GPG key

docker run -it -v /path/to/keys/store:/root/.gnupg -e GPG_TTY=/dev/console vladgh/gpg --full-gen-key

If the command complaints about more entropy start the following container in a new session on the same host

docker run --rm --privileged --entrypoint haveged vladgh/gpg -F

• Export public GPG key

docker run --rm -it -v /path/to/keys/store:/root/.gnupg -v $(pwd)/keys:/keys -e GPG_TTY=/dev/console vladgh/gpg --output /keys/my_key.pub --armor --export me@example.com

• Export private GPG key (KEEP SAFE)

docker run --rm -it -v /path/to/keys/store:/root/.gnupg -v $(pwd)/keys:/keys -e GPG_TTY=/dev/console vladgh/gpg --output /keys/my_rsa_key --armor --export-secret-key me@example.com
