OpenCT
CTAPI is a German standard for PC to smartcard reader communication, which is implemented by OpenCT. The international standard is in contrast PC/SC.
Installation
Kernel
You have to enable kernel support depending on how your cardreader is connected:
- For USB cardreader see the USB article.
- For PC-Card cardreader see the PC-Card article.
- For serial cardreader enable serial support.
USE flags
Portage knows the global openct USE flag for enabling support for OpenCT in other packages. Enabling this USE flag will pull in dev-libs/openct automatically:
/etc/portage/make.confUSE="openct"
Other USE flags of openct include:
USE flags for dev-libs/openct library for accessing smart card terminals
debug
|
Add debug output to the driver library for pcsc-lite. |
doc
|
Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally |
pcsc-lite
|
Build a driver library for sys-apps/pcsc-lite, providing PC/SC API access to devices supported by OpenCT. |
selinux
|
!!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur |
usb
|
Add USB support to applications that have optional USB support (e.g. cups) |
Emerge
After setting this you want to update your system so the changes take effect:
root #emerge --ask --changed-use --deep @worldConfiguration
Permissions
Add your user to the openct group to be able to access the cardreader:
root #gpasswd -a larry openctServices
OpenRC
To tart OpenCT:
root #/etc/init.d/openct startTo start OpenCT at boot time, add it the default runlevel:
root #rc-update add openct defaultThe OpenCT daemon blocks all detected cardreaders for every other software. An exception is, if you use the ifdhandler for PCSC-Lite.
Usage
Listing readers
List all detected cardreaders:
user $openct-tool listIf there is a detected cardreader, insert a smartcard. Test the access by checking the ATR:
user $openct-tool atrDetected CCID Compatible Card present, status changed ATR: 3B 75 94 00 00 62 02 02 03 01
