Types

type CAProtocol

type CAProtocol interface {
	// SendCSR send CSR request to the CA server.
	SendCSR(*pb.CsrRequest) (*pb.CsrResponse, error)
}

CAProtocol is the interface for talking to CA.

type GrpcConnection

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

GrpcConnection implements CAProtocol talking to CA via gRPC. TODO(incfly): investigate the overhead of maintaining gRPC connection for CA server compared with establishing new connection every time.

func NewGrpcConnection

func NewGrpcConnection(caAddr string, dialOptions []grpc.DialOption) (*GrpcConnection, error)

NewGrpcConnection creates a gRPC connection.

func (*GrpcConnection) Close

func (c *GrpcConnection) Close() error

Close closes the gRPC connection.

func (*GrpcConnection) SendCSR

func (c *GrpcConnection) SendCSR(req *pb.CsrRequest) (*pb.CsrResponse, error)

SendCSR sends a resquest to CA server and returns the response.
