• Fix cases of communication with T=0/1 cards

Improved documentation.

Bump release to trigger update at `deno.land/x/pcsc`

v0.3.1

cleanup for V0.3.0

ContextProvider and registry, reorg exports

Changes:

1. Adds ContextProvider, a static registry that

• Is a central point for obtaining Context implementations.
• Auto-registers the FFI implementation if required, when running under Deno.
• Allows additional implementations of Context to be registered, ready for card-emulator, node-compat, etc

2. Reorganized exports to facilitate tree-shaking,

• mod.ts - exports complete functionality
• iso7816/iso7816.ts exports ISO7816 types, enums and classes, non-Deno specific
• pcsc/pcsc.ts exports PC/SC types and enums, non-Deno specific
• deno-pcsc-ffi/deno-pcsc-ffi.ts exports Deno specific 'ffi' functionality

Basic functionality for HL and LL APIs.

This release includes the basic functionality for using Smartcards with Deno.

• Working low-level API - equivalent to PC/SC (winscard/pcsclite) API, useful for porting legacy applications.

• High Level abstraction for new applications, based on the following objects:

  • FFIContext - connection to PC/SC, list readers, listen for reader/card events
  • Reader - check status (PRESENT/MUTE/CONNECTED), connect to cards, listen for card events
  • Card - a connection to a powered-up smart-card, transmit APDU commands, status

Needs Deno 1.23.2 or greater for FFI functionality, along with --allow-ffi and --unstable flags.

Tests in ./tests.
