/**

 *
 * <pre>
 * Verifiers (e.g. Kritis implementations) MUST verify signatures
 * with respect to the trust anchors defined in policy (e.g. a Kritis policy).
 * Typically this means that the verifier has been configured with a map from
 * `public_key_id` to public key material (and any required parameters, e.g.
 * signing algorithm).
 * In particular, verification implementations MUST NOT treat the signature
 * `public_key_id` as anything more than a key lookup hint. The `public_key_id`
 * DOES NOT validate or authenticate a public key; it only provides a mechanism
 * for quickly selecting a public key ALREADY CONFIGURED on the verifier through
 * a trusted channel. Verification implementations MUST reject signatures in any
 * of the following circumstances:
 *   * The `public_key_id` is not recognized by the verifier.
 *   * The public key that `public_key_id` refers to does not verify the
 *     signature with respect to the payload.
 * The `signature` contents SHOULD NOT be "attached" (where the payload is
 * included with the serialized `signature` bytes). Verifiers MUST ignore any
 * "attached" payload and only verify signatures with respect to explicitly
 * provided payload (e.g. a `payload` field on the proto message that holds
 * this Signature, or the canonical serialization of the proto message that
 * holds this signature).
