recipe

object (Recipe)

metadata

object (Metadata)
materials[]

Index in materials containing the recipe steps that are not implied by recipe.type. For example, if the recipe type were "make", then this would point to the source containing the Makefile, not the make program itself. Set to -1 if the recipe doesn't come from a material, as zero is default unset value for int64.
entryPoint

string

String identifying the entry point into the build. This is often a path to a configuration file and/or a target label within that file. The syntax and meaning are defined by recipe.type. For example, if the recipe type were "make", then this would reference the directory in which to run make as well as which target to use.
arguments[]

object

Collection of all external inputs that influenced the build on top of recipe.definedInMaterial and recipe.entryPoint. For example, if the recipe type were "make", then this might be the flags passed to make aside from the target, which is captured in recipe.entryPoint. Since the arguments field can greatly vary in structure, depending on the builder and recipe type, this is of form "Any".

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
environment[]

Fields
builder

object (SlsaBuilder)

recipe

object (SlsaRecipe)

Identifies the configuration used for the build. When combined with materials, this SHOULD fully describe the build, such that re-running this recipe results in bit-for-bit identical output (if the build is reproducible). required
metadata

object (SlsaMetadata)
materials[]

object (Material)

The collection of artifacts that influenced the build including sources, dependencies, build tools, base images, and so on. This is considered to be incomplete unless metadata.completeness.materials is true. Unset or null is equivalent to empty.

string

URI indicating what type of recipe was performed. It determines the meaning of recipe.entryPoint, recipe.arguments, recipe.environment, and materials.
definedInMaterial

string (int64 format)

Index in materials containing the recipe steps that are not implied by recipe.type. For example, if the recipe type were "make", then this would point to the source containing the Makefile, not the make program itself. Set to -1 if the recipe doesn't come from a material, as zero is default unset value for int64.
entryPoint

string

String identifying the entry point into the build. This is often a path to a configuration file and/or a target label within that file. The syntax and meaning are defined by recipe.type. For example, if the recipe type were "make", then this would reference the directory in which to run make as well as which target to use.
arguments

object

Collection of all external inputs that influenced the build on top of recipe.definedInMaterial and recipe.entryPoint. For example, if the recipe type were "make", then this might be the flags passed to make aside from the target, which is captured in recipe.entryPoint. Depending on the recipe Type, the structure may be different.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
environment

object

AttestationOccurrence

Occurrence that represents a single "attestation". The authenticity of an attestation can be verified using the attached signature. If the verifier trusts the public key of the signer, then verifying the signature is sufficient to establish trust. In this circumstance, the authority to which this attestation is attached is primarily useful for lookup (how to find this attestation if you already know the authority and artifact to be verified) and intent (for which authority this attestation was intended to sign.

JSON representation 
{
  "serializedPayload": string,
  "signatures": [
    {
      object (Signature)
    }
  ],
  "jwts": [
    {
      object (Jwt)
    }
  ]
}
Fields
serializedPayload

string (bytes format)

Required. The serialized payload that is verified by one or more signatures.

A base64-encoded string.
signatures[]

object (Signature)

One or more signatures over serializedPayload. Verifier implementations should consider this attestation message verified if at least one signature verifies serializedPayload. See Signature in common.proto for more details on signature structure and verification.
jwts[]

object (Jwt)

One or more JWTs encoding a self-contained attestation. Each JWT encodes the payload that it verifies within the JWT itself. Verifier implementation SHOULD ignore the serializedPayload field when verifying these JWTs. If only JWTs are present on this AttestationOccurrence, then the serializedPayload SHOULD be left empty. Each JWT SHOULD encode a claim specific to the resourceUri of this Occurrence, but this is not validated by Grafeas metadata API implementations. The JWT itself is opaque to Grafeas.

Signature

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 publicKeyId to public key material (and any required parameters, e.g. signing algorithm).

In particular, verification implementations MUST NOT treat the signature publicKeyId as anything more than a key lookup hint. The publicKeyId 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 publicKeyId is not recognized by the verifier. * The public key that publicKeyId 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).

JSON representation 
{
  "signature": string,
  "publicKeyId": string
}
Fields
signature

string (bytes format)

The content of the signature, an opaque bytestring. The payload that this signature verifies MUST be unambiguously provided with the Signature during verification. A wrapper message might provide the payload explicitly. Alternatively, a message might have a canonical serialization that can always be unambiguously computed to derive the payload.

A base64-encoded string.
publicKeyId

string

The identifier for the public key that verifies this signature. * The publicKeyId is required. * The publicKeyId SHOULD be an RFC3986 conformant URI. * When possible, the publicKeyId SHOULD be an immutable reference, such as a cryptographic digest.

Examples of valid publicKeyIds:

OpenPGP V4 public key fingerprint: * "openpgp4fpr:74FAF3B861BDA0870C7B6DEF607E48D2A663AEEA" See https://www.iana.org/assignments/uri-schemes/prov/openpgp4fpr for more details on this scheme.

RFC6920 digest-named SubjectPublicKeyInfo (digest of the DER serialization): * "ni:///sha-256;cD9o9Cq6LG3jD0iKXqEi_vdjJGecm_iXkbqVoScViaU" * "nih:///sha-256;703f68f42aba2c6de30f488a5ea122fef76324679c9bf89791ba95a1271589a5"
