Functions

func GetConnection 

func GetConnection(connConfig *ConnectionConfig) (*grpc.ClientConn, error)

GetConnection attempts to return a connection to a gRPC server based on the provided configuration of connection details. Note that several clients can be passed the same connection, as the gRPC framework is able to multiplex several RPCs on the same connection, thus reducing the overhead.

func GetLogger 

func GetLogger() log.Logger

GetLogger returns the instance of log.Logger currently configured for this package.

func SetLogger 

func SetLogger(lgr log.Logger)

SetLogger assigns the log.Logger instance passed as argument to the logger of this package. This is to support loggers other than log.StdoutLogger, which is set as default in init function.

Types

type CLClient 

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

func NewCLClient 

func NewCLClient(conn *grpc.ClientConn) (*CLClient, error)

func (*CLClient) GetAcceptableCreds 

func (c *CLClient) GetAcceptableCreds() (map[string][]string, error)

func (*CLClient) GetCredentialStructure 

func (c *CLClient) GetCredentialStructure() (*cl.RawCred, error)

func (*CLClient) IssueCredential 

func (c *CLClient) IssueCredential(credManager *cl.CredManager, regKey string) (*cl.Cred, error)

func (*CLClient) ProveCredential 

func (c *CLClient) ProveCredential(credManager *cl.CredManager, cred *cl.Cred,
	revealedAttrs []string) (*string, error)

ProveCredential proves the possession of a valid credential and reveals only the attributes the user desires to reveal.

func (*CLClient) UpdateCredential 

func (c *CLClient) UpdateCredential(credManager *cl.CredManager, rawCred *cl.RawCred) (*cl.Cred,
	error)

type ConnectionConfig 

type ConnectionConfig struct {
	Endpoint           string // Server's Endpoint
	ServerNameOverride string // When ServerNameOverride != "",
	// server cert's CN will be compared with the provided ServerNameOverride instead of server's
	// hostname
	CACertificate []byte // CA certificate for validating the server
	TimeoutMillis int    // timeout (in millis) for establishing initial connection with the server
}

ConnectionConfig holds all the details required for establishing a connection to the server.

func NewConnectionConfig 

func NewConnectionConfig(endpoint, serverNameOverride string, certificate []byte,
	timeoutMillis int) *ConnectionConfig

type PseudonymsysCAClient 

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

func NewPseudonymsysCAClient 

func NewPseudonymsysCAClient(conn *grpc.ClientConn,
	group *schnorr.Group) (*PseudonymsysCAClient, error)

func (*PseudonymsysCAClient) GenerateCertificate 

func (c *PseudonymsysCAClient) GenerateCertificate(userSecret *big.Int, nym *pseudsys.Nym) (
	*pseudsys.CACert, error)

GenerateCertificate provides a certificate from trusted CA to the user. Note that CA needs to know the user. The certificate is then used for registering pseudonym (nym). The certificate contains blinded user's master key pair and a signature of it.

func (*PseudonymsysCAClient) GenerateMasterNym 

func (c *PseudonymsysCAClient) GenerateMasterNym(secret *big.Int) *pseudsys.Nym

GenerateMasterNym generates a master pseudonym to be used with GenerateCertificate.

type PseudonymsysCAClientEC 

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

func NewPseudonymsysCAClientEC 

func NewPseudonymsysCAClientEC(conn *grpc.ClientConn, curve ec.Curve) (*PseudonymsysCAClientEC, error)

func (*PseudonymsysCAClientEC) GenerateCertificate 

func (c *PseudonymsysCAClientEC) GenerateCertificate(userSecret *big.Int, nym *ecpseudsys.Nym) (
	*ecpseudsys.CACert, error)

GenerateCertificate provides a certificate from trusted CA to the user. Note that CA needs to know the user. The certificate is then used for registering pseudonym (nym). The certificate contains blinded user's master key pair and a signature of it.

func (*PseudonymsysCAClientEC) GenerateMasterNym 

func (c *PseudonymsysCAClientEC) GenerateMasterNym(secret *big.Int) *ecpseudsys.Nym

GenerateMasterNym generates a master pseudonym to be used with GenerateCertificate.

type PseudonymsysClient 

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

func NewPseudonymsysClient 

func NewPseudonymsysClient(conn *grpc.ClientConn,
	group *schnorr.Group) (*PseudonymsysClient, error)

func (*PseudonymsysClient) GenerateMasterKey 

func (c *PseudonymsysClient) GenerateMasterKey() *big.Int

GenerateMasterKey generates a master secret key, representing a random integer betweeen 0 and order of the group. This key will be used subsequently by all the protocols in the scheme.

func (*PseudonymsysClient) GenerateNym 

func (c *PseudonymsysClient) GenerateNym(userSecret *big.Int,
	caCertificate *pseudsys.CACert, regKey string) (
	*pseudsys.Nym, error)

GenerateNym generates a nym and registers it to the organization. Do not use the same CACert for different organizations - use it only once!

func (*PseudonymsysClient) ObtainCredential 

func (c *PseudonymsysClient) ObtainCredential(userSecret *big.Int,
	nym *pseudsys.Nym, orgPubKeys *pseudsys.PubKey) (
	*pseudsys.Cred, error)

ObtainCredential returns anonymous credential.

func (*PseudonymsysClient) TransferCredential 

func (c *PseudonymsysClient) TransferCredential(orgName string, userSecret *big.Int,
	nym *pseudsys.Nym, credential *pseudsys.Cred) (*pb.SessionKey, error)

TransferCredential transfers orgName's credential to organization where the authentication should happen (the organization takes credential issued by another organization).

type PseudonymsysClientEC 

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

func NewPseudonymsysClientEC 

func NewPseudonymsysClientEC(conn *grpc.ClientConn, curve ec.Curve) (*PseudonymsysClientEC, error)

func (*PseudonymsysClientEC) GenerateMasterKey 

func (c *PseudonymsysClientEC) GenerateMasterKey() *big.Int

GenerateMasterKey generates a master secret key to be used subsequently by all the protocols in the scheme.

func (*PseudonymsysClientEC) GenerateNym 

func (c *PseudonymsysClientEC) GenerateNym(userSecret *big.Int,
	caCertificate *ecpseudsys.CACert, regKey string) (
	*ecpseudsys.Nym, error)

GenerateNym generates a nym and registers it to the organization. Do not use the same CACert for different organizations - use it only once!

func (*PseudonymsysClientEC) ObtainCredential 

func (c *PseudonymsysClientEC) ObtainCredential(userSecret *big.Int,
	nym *ecpseudsys.Nym, orgPubKeys *ecpseudsys.PubKey) (
	*ecpseudsys.Cred, error)

ObtainCredential returns anonymous credential.

func (*PseudonymsysClientEC) TransferCredential 

func (c *PseudonymsysClientEC) TransferCredential(orgName string, userSecret *big.Int,
	nym *ecpseudsys.Nym, credential *ecpseudsys.Cred) (*pb.SessionKey, error)

TransferCredential transfers orgName's credential to organization where the authentication should happen (the organization takes credential issued by another organization).

type ServiceInfo 

type ServiceInfo struct {
	Name        string
	Description string
	Provider    string
}

ServiceInfo holds the data related to the service supported by emmy. All fields are exported to ensure access to data from any package.
