Overview

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).

Instance Attribute Summary

end

Instance Attribute Details

#public_key_id ⇒ 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_ids: OpenPGP V4 public key fingerprint: * "openpgp4fpr: 74FAF3B861BDA0870C7B6DEF607E48D2A663AEEA" See https://www.iana.org/assignments/ uri-schemes/prov/openpgp4fpr for more details on this scheme. RFC6920 digest- named SubjectPublicKeyInfo (digest of the DER serialization): * "ni:///sha-256; cD9o9Cq6LG3jD0iKXqEi_vdjJGecm_iXkbqVoScViaU" * "nih:///sha-256; 703f68f42aba2c6de30f488a5ea122fef76324679c9bf89791ba95a1271589a5" Corresponds to the JSON property publicKeyId

Returns:

• (String)

# File 'generated/google/apis/binaryauthorization_v1beta1/classes.rb', line 675

def public_key_id
  @public_key_id
end

#signature ⇒ String

The content of the signature, an opaque bytestring. The payload that this signature verifies MUST be unambiguously provided with the Signature during verification. A wrapper message might provide the payload explicitly. Alternatively, a message might have a canonical serialization that can always be unambiguously computed to derive the payload. Corresponds to the JSON property signature NOTE: Values are automatically base64 encoded/decoded in the client library.

Returns:

• (String)
