Types

type AccessControlShim

type AccessControlShim struct {
	// contains filtered or unexported fields
}

AccessControlShim wraps the object passed to chaincode for shim side handling of APIs to provide access control capabilities.

func NewAccessControlShim

func NewAccessControlShim(stub shim.ChaincodeStubInterface) *AccessControlShim

NewAccessControlShim create a new AccessControlShim instance

func (*AccessControlShim) ReadCertAttribute

func (shim *AccessControlShim) ReadCertAttribute(attributeName string) ([]byte, error)

ReadCertAttribute is used to read an specific attribute from the transaction certificate, *attributeName* is passed as input parameter to this function. Example:

attrValue,error:=stub.ReadCertAttribute("position")

func (*AccessControlShim) VerifyAttribute

func (shim *AccessControlShim) VerifyAttribute(attributeName string, attributeValue []byte) (bool, error)

VerifyAttribute is used to verify if the transaction certificate has an attribute with name *attributeName* and value *attributeValue* which are the input parameters received by this function. Example:

containsAttr, error := stub.VerifyAttribute("position", "Software Engineer")

func (*AccessControlShim) VerifyAttributes

func (shim *AccessControlShim) VerifyAttributes(attrs ...*accesscontrol.Attribute) (bool, error)

VerifyAttributes does the same as VerifyAttribute but it checks for a list of attributes and their respective values instead of a single attribute/value pair Example:

containsAttrs, error:= stub.VerifyAttributes(&attr.Attribute{"position",  "Software Engineer"}, &attr.Attribute{"company", "ACompany"})

func (*AccessControlShim) VerifySignature

func (shim *AccessControlShim) VerifySignature(certificate, signature, message []byte) (bool, error)

VerifySignature verifies the transaction signature and returns `true` if correct and `false` otherwise
