| Parameters | |
|---|---|
| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ payload |
string
Required. 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
Required. A signature over the payload. The container image digest is incorporated into the signature as follows: 1. Generate a SimpleSigning format payload that includes the container image digest. 2. Generate a signature over SHA256 digest of the payload. The signature generation process can be represented as follows: |
↳ public_key |
string
Required. An associated public key used to verify the signature. |
↳ sig_alg |
int
Required. The algorithm used to produce the container image signature. |
getPayload

getSignature
Required. A signature over the payload.
The container image digest is incorporated into the signature as follows:
- Generate a SimpleSigning format payload that includes the container image digest.
- Generate a signature over SHA256 digest of the payload.
The signature generation process can be represented as follows:
Sign(sha256(SimpleSigningPayload(sha256(Image Manifest))))
| Returns | |
|---|---|
| Type | Description |
string | |
setSignature
Required. A signature over the payload.
The container image digest is incorporated into the signature as follows:
- Generate a SimpleSigning format payload that includes the container image digest.
- Generate a signature over SHA256 digest of the payload.
The signature generation process can be represented as follows:
Sign(sha256(SimpleSigningPayload(sha256(Image Manifest))))
