public static final class Signature.Builder extends GeneratedMessageV3.Builder<Signature.Builder> implements SignatureOrBuilder
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 serializedsignature
bytes). Verifiers MUST ignore any "attached" payload and only verify signatures with respect to explicitly provided payload (e.g. apayload
field on the proto message that holds this Signature, or the canonical serialization of the proto message that holds this signature).
