APDU Channel Swift Library

Basis for all synchronous data stream communication to a security device.

This library implements the IChannel protocol for establishing the generic synchronous communication channel. An example for this type of channel is a NFC or a PCSC channel. IChannel class is extended to implement the communication channel as shown in the below example.

Example

ExampleChannel class extends the IChannel interface and implements the functionality to open, connect, transmit data(command), disconnect, and close the communication channel.

import Foundation
import InfineonChannel

public class ExampleChannel: IChannel {
    public func open(exclusive: Bool) throws {
        // TODO: Begin session to the secure element or smart card.
    }

    public func close() throws {
        // TODO: Closes the connection to the secure element or smart card.
    }

    public func connect(request: Data?) async throws -> Data {
        // TODO: Connects to the secure element or smart card for exchange of commands.
        return Data()
    }

    public func disconnect(request: Data?) throws {
        // TODO: Disconnects from the secure element or smart card.
    }

    public func reset(request: Data?) async throws {
        // TODO: Resets the state of the card.
    }

    public func transmit(stream: Data) async throws -> Data {
        // TODO: Transceive the data between the host and secure element or smart card.
        return Data()
    }

    public func isOpen() -> Bool {
        // TODO: Checks the session state.
        return true
    }

    public func isConnected() -> Bool {
        // TODO: Checks the connection state.
        return true
    }

    public func getName() -> String {
        // TODO: Gets the name of connected device.
        return ""
    }
}
