Class Signature

  • All Implemented Interfaces:

    public final class Signature
extends com.google.protobuf.GeneratedMessageV3
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 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).
