Types ¶
type Envelope ¶
type Envelope struct {
PayloadType string `json:"payloadType"`
Payload string `json:"payload"`
Signatures []interface{} `json:"signatures"`
}
Envelope is the outermost layer of the attestation, handling authentication and serialization. The format and protocol are defined in DSSE and adopted by in-toto in ITE-5. https://github.com/in-toto/attestation/blob/main/spec/README.md#envelope
type Predicate ¶
type Predicate struct {
slsa.ProvenancePredicate
// contains filtered or unexported fields
}
func NewSLSAPredicate ¶
func NewSLSAPredicate() Predicate
NewSLSAPredicate returns a new SLSA provenance predicate
func (*Predicate) AddMaterial ¶
AddMaterial adds an entry to the listo of materials
func (*Predicate) SetImplementation ¶
func (p *Predicate) SetImplementation(impl PredicateImplementation)
setImplementation sets the predicate implementation
type PredicateImplementation ¶
type Statement ¶
type Statement struct {
intoto.StatementHeader
Predicate Predicate `json:"predicate"`
// contains filtered or unexported fields
}
Statement is the middle layer of the attestation, binding it to a particular subject and unambiguously identifying the types of the predicate. https://github.com/in-toto/attestation/blob/main/spec/README.md#statement
func LoadStatement ¶
LoadStatement loads a statement from a json file
func NewSLSAStatement ¶
func NewSLSAStatement() *Statement
NewSLSAStatement creates a new attestation
func (*Statement) AddSubject ¶
AddSubject adds an entry to the listo of materials
func (*Statement) AddSubjectFromFile ¶
AddSubjectFromFile adds a subject to the list by checking a file in the filesystem
func (*Statement) ClonePredicate ¶
ClonePredicate reads a provenance metadata file from `manifestPath` and clones the predicate data to the current object.
func (*Statement) LoadPredicate ¶
LoadPredicate loads a predicate from a json file
func (*Statement) ReadSubjectsFromDir ¶
ReadSubjectsFromDir reads a directory and adds every file as a subject to the statement.
func (*Statement) SetImplementation ¶
func (s *Statement) SetImplementation(si StatementImplementation)
func (*Statement) VerifySubjects ¶
VerifySubjects checks the provenance metadata of the attestation subjects by reading them from `path`.
type StatementImplementation ¶
type StatementImplementation interface {
AddSubject(*Statement, string, common.DigestSet)
ReadSubjectsFromDir(*Statement, string) error
SubjectFromFile(string) (intoto.Subject, error)
Write(*Statement, string) error
ToJSON(s *Statement) ([]byte, error)
ClonePredicate(*Statement, string) error
VerifySubjects(path string, subjects *[]intoto.Subject) (err error)
}
