Keys
This section provides public keys of various forms. All packages released on Maven Central are signed by the current release key. Personal correspondence is signed by the current personal key. The current key policy is yearly-expiring keys, with each new set of keys being signed by the previous set. Expired/revoked keys are archived here in order to allow for the verification of old releases.
