iso7816_tx

Implement ISO7816 Smart Card T=1 Transmission protocol

The T=1 protocol are commonly called the ISO protocols. They are primarily based on the provisions of the ISO/IEC 7816 family of standards

Usage

Basic APDU Transmission

fn main() {
    use iso7816_tx::TransmissionBuilder;

    let mut buf = [0u8; 258];
    let mut t = TransmissionBuilder::new()
        .set_init_cb(open)
        .set_release_cb(close)
        .set_reset_cb(reset)
        .set_read_cb(read)
        .set_write_cb(write)
        .set_sleep_cb(sleep)
        .set_nad(15, 51)
        .build();

    let atr = t.atr().expect("Failed to get ATR");

    let capdu = &[0x80, 0xca, 0x9f, 0x7f];
    let rapdu = t.transmit(capdu, &mut buf).expect("Failed to transmit");
}

fn open() -> Result<Option<Interface>, Error> {
    // Initialize connection interface
    // ...

    Ok(Some(Interface::default()))
}

fn close(interface: Option<&Interface>) -> Result<Option<Interface>, Error> {
    // Release connection interface
    // ...

    Ok(None)
}

fn reset(interface: Option<&Interface>) -> Result<(), Error> {
    // Cold reset implementation
    // ...

    Ok(())
}

fn read(interface: Option<&Interface>, buf: &mut [u8]) -> Result<usize, Error> {
    // Read data from connection interface
    // ...

    Ok(0)
}

fn write(interface: Option<&Interface>, buf: &[u8]) -> Result<usize, Error> {
    // Write data to connection interface
    // ...

    Ok(0)
}

fn sleep(ms: u32) {
    // Sleep implementation
    // ...
}

// Connection interface context
#[derive(Default)]
struct Interface{}

// Interface errors
#[derive(Debug)]
enum Error {}
