go-libpcsclite

A golang implementation of the libpcpsclite client. It connects to the pcscd daemon over sockets.

Purpose

The goal is for major open source projects to distribute a single binary that doesn't depend on libpcsclite. It provides an extra function CheckPCSCDaemon that will tell the user if pcscd is running.

Example

func main() {
	client, err := EstablishContext(2)
	if err != nil {
    fmt.Printf("Error establishing context: %v\n", err)
    os.Exit(1)
	}

	_, err = client.ListReaders()
	if err != nil {
    fmt.Printf("Error getting the list of readers: %v\n", err)
    os.Exit(1)
	}

	card, err := client.Connect(client.readerStateDescriptors[0].Name, ShareShared, ProtocolT0|ProtocolT1)
	if err != nil {
    fmt.Printf("Error connecting: %v\n", err)
    os.Exit(1)
	}

	resp, _, err := card.Transmit([]byte{0, 0xa4, 4, 0, 0xA0, 0, 0, 8, 4, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0})

	card.Disconnect(LeaveCard)
}
