GPG key management.

Setup

  • gpg --full-generate-key - the default settings are the recommended ones.
  • gpg --edit-key martins@sitilge.id.lv - subkey for encryption has been created in the initialization step, only add a subkey for signing.
  • gpg --export-secret-keys --armor martins@sitilge.id.lv > privkey.asc - create the private key backup. Store in a safe place.
  • gpg --generate-revocation --armor martins@sitilge.id.lv > revoke.asc - create the revocation certificate. Store in a safe place.
  • gpg --list-secret-keys --with-keygrip - list all secret keys with their keygrips. Note that a keygrip is not an id but more like a file name of the key. Key id looks similar to ssb rsa2048/0xA2C4A5CDABE2CAEA 2019-01-01 [E], where A2C4A5CDABE2CAEA is the key id.
  • gpg --export-secret-subkeys --armor [encryption subkey id]! > encryption.gpg - export the encryption subkey ([E] in the list of keys).
  • gpg --export-secret-subkeys --armor [signing subkey id]! > signing.gpg - export the signing subkey ([S] in the list of keys).
  • gpg --import encryption.gpg signing.gpg - import the public subkey, the encryption subkey, and the signing subkey.
  • gpg --send-keys [key id] - send the key to a keyserver.
  • gpg --delete-secret-keys [key id] - delete the master key.
