Identity interface defining operations associated to a "certificate". That is, the public part of the identity could be thought to be a certificate, and offers solely signature verification capabilities. This is to be used at the peer side when verifying certificates that transactions are signed with, and verifying signatures that correspond to these certificates.///
type Identity interface {
// ExpiresAt returns the time at which the Identity expires.
// If the returned time is the zero value, it implies
// the Identity does not expire, or that its expiration
// time is unknown
ExpiresAt() time.Time
// GetIdentifier returns the identifier of that identity
GetIdentifier() *IdentityIdentifier
// GetMSPIdentifier returns the MSP Id for this instance

// will check the TCert signature against the assumed root certificate
// authority.
Validate() error
// GetOrganizationalUnits returns zero or more organization units or
// divisions this identity is related to as long as this is public
// information. Certain MSP implementations may use attributes
// that are publicly associated to this identity, or the identifier of
// the root certificate authority that has provided signatures on this
// certificate.
// Examples:
// - if the identity is an x.509 certificate, this function returns one
// or more string which is encoded in the Subject's Distinguished Name
// of the type OU
// TODO: For X.509 based identities, check if we need a dedicated type
// for OU where the Certificate OU is properly namespaced by the
// signer's identity
GetOrganizationalUnits() []*OUIdentifier
// Anonymous returns true if this is an anonymous identity, false otherwise

IdentityDeserializer is implemented by both MSPManger and MSP

IdentityIdentifier is a holder for the identifier of a specific identity, naturally namespaced, by its provider identifier.
type IdentityIdentifier struct {
// The identifier of the associated membership service provider
Mspid string
// The identifier for an identity within a provider
Id string
}

func New(opts NewOpts) (MSP, error)
New create a new MSP instance depending on the passed Opts
MSPManager is an interface defining a manager of one or more MSPs. This essentially acts as a mediator to MSP calls and routes MSP related calls to the appropriate MSP. This object is immutable, it is initialized once and never changed.

type NewBaseOpts struct {

func (o *NewBaseOpts) GetVersion() MSPVersion
NewOpts represent
type NewOpts interface {

NodeOUs contains information on how to tell apart clients, peers and orderers based on OUs. If the check is enforced, by setting Enabled to true, the MSP will consider an identity valid if it is an identity of a client, a peer or an orderer. An identity should have only one of these special OUs.
type NodeOUs struct {
// Enable activates the OU enforcement
Enable bool `yaml:"Enable,omitempty"`
// ClientOUIdentifier specifies how to recognize clients by OU

OUIdentifier represents an organizational unit and its related chain of trust identifier.

// CertifiersIdentifier is the hash of certificates chain of trust
// related to this organizational unit
CertifiersIdentifier []byte
// OrganizationUnitIdentifier defines the organizational unit under the
// MSP identified with MSPIdentifier

OrganizationalUnitIdentifiersConfiguration is used to represent an OU and an associated trusted certificate
type OrganizationalUnitIdentifiersConfiguration struct {
// Certificate is the path to a root or intermediate certificate
Certificate string `yaml:"Certificate,omitempty"`
// OrganizationalUnitIdentifier is the name of the OU
OrganizationalUnitIdentifier string `yaml:"OrganizationalUnitIdentifier,omitempty"`

ProviderType indicates the type of an identity provider
type ProviderType int
The ProviderType of a member relative to the member API
const (
FABRIC ProviderType = iota // MSP is of FABRIC type
IDEMIX // MSP is of IDEMIX type
OTHER // MSP is of OTHER TYPE
)
Role : Represents a IdemixRole
type Role int32
The expected roles are 4; We can combine them using a bitmask
const (
MEMBER Role = 1
ADMIN Role = 2
CLIENT Role = 4
PEER Role = 8
)
SigningIdentity is an extension of Identity to cover signing capabilities. E.g., signing identity should be requested in the case of a client who wishes to sign transactions, or fabric endorser who wishes to sign proposal processing outcomes.
type SigningIdentity interface {
// Extends Identity
Identity
// Sign the message
Sign(msg []byte) ([]byte, error)
// GetPublicVersion returns the public parts of this identity
