Types

type CAClient

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

func NewCAClient(cfg *config.Config, userHomeDir ...string) (*CAClient, error)

NewCAClient initializes and returns a new Fabric CA client using configuration from the config package

func (*CAClient) Enroll

func (c *CAClient) Enroll(request *api.EnrollmentRequest) (*lib.Identity, error)

Enroll performs the enrollment process for a user or administrator. It takes an api.EnrollmentRequest and returns the resulting lib.Identity or an error.

func (*CAClient) EnrollAdmin

func (c *CAClient) EnrollAdmin() (*lib.Identity, error)

type GWClient

type GWClient struct {
	*client.Gateway
}

GWClient wraps the Fabric Gateway client.

func NewGatewayClient

func NewGatewayClient(ctx context.Context, conf ...config.Config) (*GWClient, error)

NewGatewayClient creates a new Fabric Gateway client. It establishes a gRPC connection to the Fabric peer, creates user identity and signing objects, and returns a GWClient instance for interacting with the Fabric network.

type MSPKeyCert

	Cert string `json:"msp.crt"`
	Key  string `json:"msp.key"`
}
