Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ payload string

Optional. The binary signature payload following the SimpleSigning format https://github.com/sigstore/cosign/blob/main/specs/SIGNATURE_SPEC.md#simple-signing. This payload includes the container image digest.
↳ signature string

Optional. A signature over the payload. The container image digest is incorporated into the signature as follows: 1.
