The opensc-tool utility can be used from the command line to perform miscellaneous smart card operations such as getting the card ATR or sending arbitrary APDU commands to a card.
Print the OpenSC package release version.
- --atr, -a
Print the Answer To Reset (ATR) of the card. Output is in hex byte format
- --card-driver driver, -c driver
Use the given card driver. The default is to auto-detect the correct card driver. The literal value ? lists all available card drivers.
Lists algorithms supported by card
- --info, -i
Print information about OpenSC, such as version and enabled components.
- --list-drivers, -D
List all installed card drivers.
- --list-files, -f
Recursively list all files stored on card.
- --list-readers, -l
List all configured readers.
- --name, -n
Print the name of the inserted card (driver).
- --get-conf-entry conf, -G conf
Get configuration key, format: section:name:key
- --set-conf-entry conf, -S conf
Set configuration key, format: section:name:key:value
- --reader arg, -r arg
Number of the reader to use. By default, the first reader with a present card is used. If arg is an ATR, the reader with a matching card will be chosen.
- --reset [type],
Resets the card in reader. The default reset type is cold, but warm reset is also possible.
- --send-apdu apdu, -s apdu
Sends an arbitrary APDU to the card in the format AA:BB:CC:DD:EE:FF.... Use this option multiple times to send more than one APDU.
The built-in card drivers may send additional APDUs for detection and initialization. To avoid this behavior, you may additionally specify --card-driver default.
Print the card serial number (normally the ICCSN). Output is in hex byte format
- --verbose, -v
Causes opensc-tool to be more verbose. Specify this flag several times to enable debug output in the opensc library.
- --wait, -w
Wait for a card to be inserted.
