    Returns:
      An object of the form:

      "nextPageToken": "A String", # Token to provide to skip to a particular spot in the list.

            "attestation": { # Occurrence that represents a single "attestation". The authenticity of an attestation can be verified using the attached signature. If the verifier trusts the public key of the signer, then verifying the signature is sufficient to establish trust. In this circumstance, the authority to which this attestation is attached is primarily useful for look-up (how to find this attestation if you already know the authority and artifact to be verified) and intent (which authority was this attestation intended to sign for). # Required.

                  { # 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).
                    "publicKeyId": "A String", # The identifier for the public key that verifies this signature. * The `public_key_id` is required. * The `public_key_id` SHOULD be an RFC3986 conformant URI. * When possible, the `public_key_id` SHOULD be an immutable reference, such as a cryptographic digest. Examples of valid `public_key_id`s: OpenPGP V4 public key fingerprint: * "openpgp4fpr:74FAF3B861BDA0870C7B6DEF607E48D2A663AEEA" See https://www.iana.org/assignments/uri-schemes/prov/openpgp4fpr for more details on this scheme.

Implementations may choose to acknowledge "LONG", "SHORT", or other abbreviated key IDs, but only the full fingerprint is guaranteed to work. In gpg, the full fingerprint can be retrieved from the `fpr` field returned when calling --list-keys with --with-colons. For example: ``` gpg --with-colons --with-fingerprint --force-v4-certs \ --list-keys attester@example.com tru::1:1513631572:0:3:1:5 pub:...... fpr:::::::::24FF6481B76AC91E66A00AC657A93A81EF3AE6FB: ``` Above, the fingerprint is `24FF6481B76AC91E66A00AC657A93A81EF3AE6FB`.
                "signature": "A String", # Required. The raw content of the signature, as output by GNU Privacy Guard (GPG) or equivalent. Since this message only supports attached signatures, the payload that was signed must be attached. While the signature format supported is dependent on the verification implementation, currently only ASCII-armored (`--armor` to gpg), non-clearsigned (`--sign` rather than `--clearsign` to gpg) are supported. Concretely, `gpg --sign --armor --output=signature.gpg payload.json` will create the signature content expected in this field in `signature.gpg` for the `payload.json` attestation payload.
