pcsc-lite is a Free Software implementation of the PC/SC (or WinSCard) API for Unix systems.

Changes:
1.8.22: Ludovic Rousseau
17 June 2017
  • SCardCancel() was broken in 1.8.21. The call was blocking.
  • Enable use of info level logging for pcscd using -i/--info

pcsc_scan on Windows

Since version 1.5.0 of pcsc-tools (see "New version of pcsc-tools: 1.5.0, 1.5.1, 1.5.2") it is possible to build and run pcsc_scan on Windows.

MSYS2

From the project webpage:

MSYS2 is a software distro and building platform for Windows


At its core is an independent rewrite of MSYS, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. It provides a bash shell, Autotools, revision control systems and the like for building native Windows applications using MinGW-w64 toolchains.

It features a package management system to provide easy installation of packages, Pacman. It brings many powerful features such as dependency resolution and simple complete system upgrades, as well as straight-forward package building.

Using MSYS2 it is easy to build/port a Unix program on Windows.

Build

To build the program use the classic sequence:
  1. ./configure
  2. make

$ ./configure
configure: loading site script /etc/config.site
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes

configure: creating ./config.status

Windows does not use pcsc-lite but its own natice WinSCard implementation. So it is not surprising that libpcsclite is not found by the configure script. What is important is that the header file winscard.h is found and that the function SCardEstablishContext() can be used.

$ make
make  all-am
make[1] : on entre dans le répertoire « /home/Ludovic/pcsc-tools »
  CC       pcsc_scan-pcsc_scan.o
  CCLD     pcsc_scan.exe
make[1] : on quitte le répertoire « /home/Ludovic/pcsc-tools »

Run

$ ./pcsc_scan.exe
PC/SC device scanner
V 1.5.2 (c) 2001-2017, Ludovic Rousseau

 Reader 1: Broadcom Corp Contactless SmartCard 0
  Card state: Card removed, 
 Reader 2: \\?PnP?\Notification
  Card state: 

Limitations

The program has some limitations:
  • the special reader name \\?PnP?\Notification, used for reader hotplug events, has its name listed.
    This is not the case on GNU/Linux or macOS.
  • the program does not exit when the key sequence Ctrl-C is used. On Unix the Control-C sequence is used to send a SIGINT signal to the process. On Windows I do not know an equivalent.
    To quit pcsc_scan you have to terminate the process using the task manager. Not really a good User eXperience.

Conclusion

I do not plan to put a lot of effort into the Windows version of pcsc_scan. It was just an experiment.

If you want a change you can submit a Pull Request at the pcsc-tools github project.

New PyKCS11 1.4.2 available

I just released a new version of PyKCS11, a Python wrapper above the PKCS#11 API.

See PyKCS11 introduction for more details about PyKCS11.

Changes:
1.4.2 - May 2017, Ludovic Rousseau
  • Moved the project from https://bitbucket.org/PyKCS11/pykcs11 to https://github.com/LudovicRousseau/PyKCS11
  • Makefile: use a better default value for PREFIX
  • Fix PyKCS11.__del__(): test that every module is accessible
  • getSlotList(): add optional tokenPresent parameter
    By default the method returns all the slots (like before the change).
  • Always call C_Initialize() in ::Load() to work with some bogus PKCS#11 library (like libCryptoki2 from Safenet Luna SA HSM)
  • LowLevel samples: use PYKCS11LIB environment variable
  • some minor improvements

Google Open Source Peer Bonus winner

I am pleased to announce that I am one of the 2017 "Google Open Source Peer Bonus winners" for my work on pcsc-lite and the CCID driver.

The latest round of Google Open Source Peer Bonus winners


Monday, March 27, 2017
Google relies on open source software throughout our systems, much of it written by non-Googlers. We’re always looking for ways to say “thank you!” so 5 years ago we started asking Googlers to nominate open source contributors outside of the company who have made significant contributions to codebases we use or think are important. We’ve recognized more than 500 developers from 30+ countries who have contributed their time and talent to over 400 open source projects since the program’s inception in 2011. Today we are pleased to announce the latest round of awardees, 52 individuals we’d like to recognize for their dedication to open source communities. The following is a list of everyone who gave us permission to thank them publicly:

Congratulations to all of the awardees, past and present! Thank you for your contributions.
By Helen Hu, Open Source Programs Office

The bonus (I should receive) is a credit card with 250$.

That is not much compared to Google annual profit. Google operating profit for 2016 was 30 419 M$.
My bonus part is 250 / 30 419 000 000 = 0.000 000 008 218 548.

That is not much for Google, but this is twice the amount I received in bitcoin for now ("How to help my projects? Send me bitcoins!").
