Functions

func CommitterFrom 

func CommitterFrom(connect *grpc.ClientConn) orderer.AtomicBroadcastClient

func DERToPrivateKey 

func DERToPrivateKey(der []byte) (key interface{}, err error)

DERToPrivateKey unmarshal a der to private key

func FindKeyFilesOrPanic 

func FindKeyFilesOrPanic(dirname string) []string

func GetContractMetadata added in v0.0.10 

func GetContractMetadata(ctx context.Context, connection grpc.ClientConnInterface, signingIdentity format.MessageSigningIdentity, channelID, chaincodeName string) (cm metadata.ContractChaincodeMetadata)

Only works when using the Contract API for your chaincode implementation , your chaincode should have a "org.hyperledger.fabric:GetMetadata" transaction function that will provide you with information on the smart contracts and transaction functions contained in the chaincode.

func GetPrivateKey 

func GetPrivateKey(f string) (*ecdsa.PrivateKey, error)

func IsLowS 

func IsLowS(k *ecdsa.PublicKey, s *big.Int) (bool, error)

func ListChannelOnPeer added in v0.0.9 

func ListChannelOnPeer(ctx context.Context, connection grpc.ClientConnInterface, crypto *Crypto) (results []string)

func PEMtoPrivateKey 

func PEMtoPrivateKey(raw []byte, pwd []byte) (interface{}, error)

PEMtoPrivateKey unmarshal a pem to private key

func Ping 

func Ping(target string, params Params) (connect *grpc.ClientConn, err error)

func PingOrPanic added in v0.0.11 

func PingOrPanic(target string, params Params) *grpc.ClientConn

func ToAddress 

func ToAddress(url string) string

ToAddress is a utility function to trim the GRPC protocol prefix as it is not needed by GO 

If the GRPC protocol is not found, the url is returned unchanged

func ToLowS 

func ToLowS(k *ecdsa.PublicKey, s *big.Int) (*big.Int, bool, error)
