public
An ordered list of Ed25519 public keys to use for validating signed requests. You must specify public_keys or validation_shared_keys (or both). The keys in public_keys are checked first. You may specify no more than one Google-managed public key. If you specify public_keys, you must specify at least one (1) key and may specify up to three (3) keys. Ed25519 public keys are not secret, and only allow Google to validate a request was signed by your corresponding private key. Ensure that the private key is kept secret, and that only authorized users can add public keys to a keyset. Structure is documented below.
