     .SH "SYNOPSIS"

	  .HP 288u

	       opensc-tool		   [OPTIONS]



     .SH "DESCRIPTION"

		     .PP 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.



     .SH "OPTIONS"

		     .PP


		    .PP --version

							    Print the OpenSC
	 package release version.

			     .RE		     .PP --atr, -a

								Print the Answer
	     To Reset (ATR) of the card. Output is in hex byte format

				 .RE			 .PP --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.

				     .RE		     .PP
		 --list-algorithms,

									Lists
		     algorithms supported by card

					 .RE			 .PP --info, -i


						  Print information about
			 OpenSC, such as version and enabled components.

					     .RE		     .PP
			 --list-drivers, -D


						      List all installed card
			     drivers.

						 .RE			 .PP
			     --list-files, -f


							  Recursively list all
				 files stored on card.

						     .RE		     .PP
				 --list-readers, -l


							      List all
				     configured readers.

							 .RE
							 .PP --name, -n


								  Print the name
					 of the inserted card (driver).

							     .RE
							     .PP
					 --get-conf-entry conf, -G conf


								      Get
					     configuration key, format:
					     section:name:key

								 .RE
								 .PP
					     --set-conf-entry conf, -S conf


									  Set
						 configuration key, format:
						 section:name:key:value

								     .RE
								     .PP
						 --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.


									 .RE
									 .PP
						     --reset [type],


										  Resets
							 the card in reader. The
							 default reset type is
							 cold, but warm reset is
							 also possible.

									     .RE
									     .PP
							 --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.


										 .RE
										 .PP
							     --serial


											  Print
								 the card serial
								 number
								 (normally the
								 ICCSN). Output
								 is in hex byte
								 format

										     .RE
										     .PP
								 --verbose, -v


											      Causes
								     opensc-tool

								     this flag
								     several

								     enable
								     debug
