type BCCSPNewOpts struct {
	NewBaseOpts
}

BCCSPNewOpts contains the options to instantiate a new BCCSP-based (X509) MSP

type Configuration 

type Configuration struct {
	// OrganizationalUnitIdentifiers is a list of OUs. If this is set, the MSP
	// will consider an identity valid only it contains at least one of these OUs
	OrganizationalUnitIdentifiers []*OrganizationalUnitIdentifiersConfiguration `yaml:"OrganizationalUnitIdentifiers,omitempty"`
	// NodeOUs enables the MSP to tell apart clients, peers and orderers based
	// on the identity's OU.
	NodeOUs *NodeOUs `yaml:"NodeOUs,omitempty"`
}

Configuration represents the accessory configuration an MSP can be equipped with. By default, this configuration is stored in a yaml file

type IdemixNewOpts 

type IdemixNewOpts struct {
	NewBaseOpts
}

IdemixNewOpts contains the options to instantiate a new Idemix-based MSP

type Identity 

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
	GetMSPIdentifier() string

	// Validate uses the rules that govern this identity to validate it.
	// E.g., if it is a fabric TCert implemented as identity, validate
	// 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
	Anonymous() bool

	// Verify a signature over some message using this identity as reference
	Verify(msg []byte, sig []byte) error

	// Serialize converts an identity to bytes
	Serialize() ([]byte, error)

	// SatisfiesPrincipal checks whether this instance matches
	// the description supplied in MSPPrincipal. The check may
	// involve a byte-by-byte comparison (if the principal is
	// a serialized identity) or may require MSP validation
	SatisfiesPrincipal(principal *msp.MSPPrincipal) error
}

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 IdentityDeserializer 

type IdentityDeserializer interface {
	// DeserializeIdentity deserializes an identity.
	// Deserialization will fail if the identity is associated to
	// an msp that is different from this one that is performing
	// the deserialization.
	DeserializeIdentity(serializedIdentity []byte) (Identity, error)

	// IsWellFormed checks if the given identity can be deserialized into its provider-specific form
	IsWellFormed(identity *msp.SerializedIdentity) error
}

IdentityDeserializer is implemented by both MSPManger and MSP

type IdentityIdentifier 

type IdentityIdentifier struct {

	// The identifier of the associated membership service provider
	Mspid string

	// The identifier for an identity within a provider
	Id string
}

IdentityIdentifier is a holder for the identifier of a specific identity, naturally namespaced, by its provider identifier.

type MSP 

type MSP interface {

	// IdentityDeserializer interface needs to be implemented by MSP
	IdentityDeserializer

	// Setup the MSP instance according to configuration information
	Setup(config *msp.MSPConfig) error

	// GetVersion returns the version of this MSP
	GetVersion() MSPVersion

	// GetType returns the provider type
	GetType() ProviderType

	// GetIdentifier returns the provider identifier
	GetIdentifier() (string, error)

	// GetSigningIdentity returns a signing identity corresponding to the provided identifier
	GetSigningIdentity(identifier *IdentityIdentifier) (SigningIdentity, error)

	// GetDefaultSigningIdentity returns the default signing identity
	GetDefaultSigningIdentity() (SigningIdentity, error)

	// GetTLSRootCerts returns the TLS root certificates for this MSP
	GetTLSRootCerts() [][]byte

	// GetTLSIntermediateCerts returns the TLS intermediate root certificates for this MSP
	GetTLSIntermediateCerts() [][]byte

	// Validate checks whether the supplied identity is valid
	Validate(id Identity) error

	// SatisfiesPrincipal checks whether the identity matches
	// the description supplied in MSPPrincipal. The check may
	// involve a byte-by-byte comparison (if the principal is
	// a serialized identity) or may require MSP validation
	SatisfiesPrincipal(id Identity, principal *msp.MSPPrincipal) error
}

MSP is the minimal Membership Service Provider Interface to be implemented to accommodate peer functionality

func New 

func New(opts NewOpts) (MSP, error)

New create a new MSP instance depending on the passed Opts

type MSPManager 

type MSPManager interface {

	// IdentityDeserializer interface needs to be implemented by MSPManager
	IdentityDeserializer

	// Setup the MSP manager instance according to configuration information
	Setup(msps []MSP) error

	// GetMSPs Provides a list of Membership Service providers
	GetMSPs() (map[string]MSP, error)
}

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.

func NewMSPManager 

func NewMSPManager() MSPManager

NewMSPManager returns a new MSP manager instance; note that this instance is not initialized until the Setup method is called

type MSPVersion 

type MSPVersion int

type NewBaseOpts 

type NewBaseOpts struct {
	Version MSPVersion
}

NewBaseOpts is the default base type for all MSP instantiation Opts

func (*NewBaseOpts) GetVersion 

func (o *NewBaseOpts) GetVersion() MSPVersion

type NewOpts 

type NewOpts interface {
	// GetVersion returns the MSP's version to be instantiated
	GetVersion() MSPVersion
}

NewOpts represent

type NodeOUs 

type NodeOUs struct {
	// Enable activates the OU enforcement
	Enable bool `yaml:"Enable,omitempty"`
	// ClientOUIdentifier specifies how to recognize clients by OU
	ClientOUIdentifier *OrganizationalUnitIdentifiersConfiguration `yaml:"ClientOUIdentifier,omitempty"`
	// PeerOUIdentifier specifies how to recognize peers by OU
	PeerOUIdentifier *OrganizationalUnitIdentifiersConfiguration `yaml:"PeerOUIdentifier,omitempty"`
}

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 OUIdentifier 

type OUIdentifier struct {
	// 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
	OrganizationalUnitIdentifier string
}

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

type OrganizationalUnitIdentifiersConfiguration 

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"`
}

OrganizationalUnitIdentifiersConfiguration is used to represent an OU and an associated trusted certificate

type ProviderType 

type ProviderType int

ProviderType indicates the type of an identity provider 

const (
	FABRIC ProviderType = iota // MSP is of FABRIC type
	IDEMIX                     // MSP is of IDEMIX type
	OTHER                      // MSP is of OTHER TYPE

)

The ProviderType of a member relative to the member API

type Role 

type Role int32

Role : Represents a IdemixRole 

const (
	MEMBER Role = 1
	ADMIN  Role = 2
	CLIENT Role = 4
	PEER   Role = 8
)

The expected roles are 4; We can combine them using a bitmask

type SigningIdentity 

type SigningIdentity interface {

	// Extends Identity
	Identity

	// Sign the message
	Sign(msg []byte) ([]byte, error)

	// GetPublicVersion returns the public parts of this identity
	GetPublicVersion() Identity
}

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.
