Types

type Client

type Client interface {
	GetIssuerPubKey() (*scheme.IssuerPublicKey, error)
	GetCSP() bccsp.BCCSP
}

Client represents a client that will load/store an Idemix credential

type Credential

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

Credential represents an Idemix credential. Implements Credential interface

func NewCredential

func NewCredential(signerConfigFile string, c Client, id idemix4.CurveID) *Credential

NewCredential is constructor for idemix.Credential

func (*Credential) CreateToken

func (cred *Credential) CreateToken(req *http.Request, reqBody []byte) (string, error)

CreateToken creates authorization token based on this Idemix credential

func (*Credential) EnrollmentID

func (cred *Credential) EnrollmentID() (string, error)

EnrollmentID returns enrollment ID associated with this Idemix credential

func (*Credential) Load

func (cred *Credential) Load() error

Load loads the Idemix credential from the location specified by the signerConfigFile attribute

func (*Credential) RevocationHandle

func (cred *Credential) RevocationHandle() (string, error)

RevocationHandle returns revocation handle associated with this Idemix credential

func (*Credential) RevokeSelf

func (cred *Credential) RevokeSelf() (*api.RevocationResponse, error)

RevokeSelf revokes this Idemix credential

func (*Credential) SetVal

func (cred *Credential) SetVal(val interface{}) error

SetVal sets *SignerConfig for this Idemix credential

func (*Credential) Store

func (cred *Credential) Store() error

Store stores this Idemix credential to the location specified by the signerConfigFile attribute

func (*Credential) Type

func (cred *Credential) Type() string

Type returns Idemix

func (*Credential) Val

func (cred *Credential) Val() (interface{}, error)

Val returns *SignerConfig associated with this Idemix credential

type SignerConfig

type SignerConfig struct {
	// Cred represents the serialized idemix credential of the default signer
	Cred []byte `protobuf:"bytes,1,opt,name=Cred,proto3" json:"Cred,omitempty"`
	// Sk is the secret key of the default signer, corresponding to credential Cred
	Sk []byte `protobuf:"bytes,2,opt,name=Sk,proto3" json:"Sk,omitempty"`
	// OrganizationalUnitIdentifier defines the organizational unit the default signer is in
	OrganizationalUnitIdentifier string `` /* 140-byte string literal not displayed */
	// Role defines whether the default signer is admin, member, peer, or client
	Role int `protobuf:"varint,4,opt,name=role,json=role" json:"role,omitempty"`
	// EnrollmentID contains the enrollment id of this signer
	EnrollmentID string `protobuf:"bytes,5,opt,name=enrollment_id,json=enrollmentId" json:"enrollment_id,omitempty"`
	// CRI contains a serialized Credential Revocation Information
	CredentialRevocationInformation []byte `` /* 156-byte string literal not displayed */
	// CurveID specifies the name of the Idemix curve to use, defaults to 'amcl.Fp256bn'
	CurveID string `protobuf:"bytes,7,opt,name=curve_id,json=curveID" json:"curveID,omitempty"`
	// RevocationHandle is the handle used to single out this credential and determine its revocation status
	RevocationHandle string `protobuf:"bytes,8,opt,name=revocation_handle,json=revocationHandle,proto3" json:"revocation_handle,omitempty"`
}
