other	ContainerImageSignature

Properties

Payload

public ByteString Payload { get; set; }

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.

Property Value
Type	Description
ByteString

PublicKey

public ByteString PublicKey { get; set; }

Optional. Reserved for future use.

Property Value
Type	Description
ByteString

SigAlg

public SigningAlgorithm SigAlg { get; set; }

Optional. Reserved for future use.

Property Value
Type	Description
SigningAlgorithm

Signature

public ByteString Signature { get; set; }

Optional. 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: Sign(sha256(SimpleSigningPayload(sha256(Image Manifest))))
