Crate iso7816_tx

ISO7816 Smart Card T=1 Transmission protocol

This Library provides ISO/IEC 7816 T=1 transmission protocol in ‘no_std’ environment.

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

Examples

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

// Interface errors
