Types

type AttestationParams

type AttestationParams struct {
	Params []string `json:"params"`
}

TODO replace this with a proto? TBD

type IdentityEvaluator

type IdentityEvaluator struct {
}

func (*IdentityEvaluator) EvaluateCreatorIdentity

func (id *IdentityEvaluator) EvaluateCreatorIdentity(creatorIdentityBytes []byte, ownerMSP string) error

EvaluateCreatorIdentity check that two identities have the same msp id. This function requires marshalled msp.SerializedIdentity as inputs.

type IdentityEvaluatorInterface

type IdentityEvaluatorInterface interface {
	EvaluateCreatorIdentity(creatorIdentityBytes []byte, ownerMSP string) error
}

type PolicyEvaluator

type PolicyEvaluator struct {
}

func (*PolicyEvaluator) EvaluateIdentity

func (id *PolicyEvaluator) EvaluateIdentity(policyBytes []byte, identityBytes []byte) error

EvaluateIdentity checks that the provided identity is a valid endorser as specified in the endorsement policy This function requires a marshalled pb.ApplicationPolicy and a marshalled msp.SerializedIdentity as input.

type PolicyEvaluatorInterface

type PolicyEvaluatorInterface interface {
	EvaluateIdentity(policyBytes []byte, identityBytes []byte) error
}

func NewPolicyEvaluator

func NewPolicyEvaluator() PolicyEvaluatorInterface

type Response

type Response struct {
	ResponseData []byte `json:"ResponseData"`
	Signature    []byte `json:"Signature"`
	PublicKey    []byte `json:"PublicKey"`
}

Response contains the response data and signature produced by the enclave TODO remove once ecc uses new ChaincodeResponseMessage

func UnmarshalResponse

func UnmarshalResponse(respBytes []byte) (*Response, error)
