GPG

Generate a key

Follow the prompts after running the following command.

gpg --full-gen-key

Export a key

Useful if you want to copy a key to another server.

gpg --export-secret-key -a -o example.pgp me@example.com

Import a key

gpg -i example.pgp

Revoke a key

Find the ID of the key you want to revoke (e.g., 21D5D74C) and create a revocation certificate.

KEY_ID="21D5D74C"
REVOCATION_CERTIFICATE="$KEY_ID.asc"
gpg --output $REVOCATION_CERTIFICATE --gen-revoke $KEY_ID

Import the revocation certificate into your GPG client.

gpg --import $REVOCATION_CERTIFICATE

View the revocation was applied.

gpg -k $KEY_ID

Push revocation to key servers.

gpg --send-keys KEY_ID

Create a GPG container

docker run -it --rm -v ${PWD}/example.pgp:/example.pgp alpine
apk add gnupg
gpg
