NAMEopensc-explorer − generic interactive utility for accessing smart card and similar security token functions

SYNOPSISopensc−explorer [OPTIONS] [SCRIPT]

DESCRIPTIONThe opensc−explorer utility can be used to perform miscellaneous operations such as exploring the contents of or sending arbitrary APDU commands to a smart card or similar security token​. If a SCRIPT is given, opensc−explorer runs in non−interactive mode, reading the commands from SCRIPT, one command per line​. If no script is given, opensc−explorer runs in interactive mode, reading commands from standard input​.

OPTIONSThe following are the command−line options for opensc−explorer​. There are additional interactive commands available once it is running​. −−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 and terminates opensc−explorer​. −−mf path, −m path Select the file referenced by the given path on startup​. The default is the path to the standard master file, 3F00​. If path is empty (e​.g​. opensc−explorer −−mf ""), then no file is explicitly selected​. −−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​. −−verbose, −v Cause opensc−explorer 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​.

COMMANDSopensc−explorer supports commands with arguments at its interactive prompt or in script files passed via the command line parameter SCRIPT​. Similar to a command shell like e​.g​. bash, each input line is split into white−space separated words​. Of these words, the first one is used as the command, while the remaining ones are treated as arguments to that command​. The following commands are supported: # ... Treat line as a comment​. Ignore anything until the end of the line introduced by #​. apdu data... Send a custom APDU command to the card​. data is a series of sequences of hexadecimal values and strings enclosed in double quotes ("​.​.​.")​. asn1 file−id [rec−no] [offs] Parse and print the ASN​.1 encoded content of the working EF specified by file−id​. If the optional parameter rec−no is given and the file is a record−oriented EF, parse and print only the record indicated by this parameter​. If the optional parameter offs is given, start parsing and printing the file or record at the offset indicated by the value given​. If this parameter is not given, the default offset is 0​. cat [file−id | sfi:short−id] [rec−no] Print the contents of the working EF specified by file−id or the short file id short−id​. If the optional second parameter rec−no is given, only print the record indicated by this parameter​. If no argument is given, print the the contents of the currently selected EF​. cd {​.​. | file−id | aid:DF−name} Change to another DF specified by the argument passed​. If the argument given is ​.​., then move up one level in the file system hierarchy​. If it is a file−id, which must be a DF directly beneath the current DF, then change to that DF​. If it is an application identifier given as aid:DF−name, then jump to the MF of the application denoted by DF−name​. change CHVpin−ref [[old−pin] new−pin] Change the PIN specified by pin−ref from the value given by old−pin and change its value to new−pin​. old−pin and new−pin can be sequences of hexadecimal values, strings enclosed in double quotes ("​.​.​."), empty (""), or absent​. If absent, the values are read from the card reader's pin pad​. Examples: change CHV2 00:00:00:00:00:00 "foobar" Change PIN CHV2 to the new value foobar, giving the old value 00:00:00:00:00:00​. change CHV2 "foobar" Set PIN CHV2 to the new value foobar​. change CHV2 Change PIN CHV2 using the card reader's pinpad​. create file−id size Create a new EF​. file−id specifies the numeric id, and size the size of the EF to create​. debug [level] Set OpenSC debug level to level​. If level is omitted, show the current debug level​. delete file−id Remove the EF or DF specified by file−id​. do_get hex−tag [output] Copy the contents of the card's data object (DO) specified by hex−tag to the local host computer's file named output​. If output is not given, the contents of hex−tag will be displayed as hex−dump​. do_put hex−tag data Change the contents of the card's data object (DO) specified by hex−tag to data​. data is either a sequence of hexadecimal values or a string enclosed in double quotes ("​.​.​.")​. echo string... Print the strings given​. erase Erase the card, if the card supports it​. get file−id [output] Copy an EF to a local file​. The local file is specified by output while the card file is specified by file−id​. If output is omitted, the name of the output file will be derived from the full card path to file−id​. get_record file−id rec−no [output] Copy a record of a record−oriented EF to a local file​. The local file is specified by output while the card file and the record are specified by file−id and rec−no, If output is omitted, the name of the output file will be derived from the full card path to file−id​. and the rec−no​. help [pattern] Display the list of available commands, their options and parameters together with a short help text​. If pattern is given, the commands shown are limited to those matching pattern​. info [file−id] Display attributes of a file specified by file−id​. If file−id is not supplied, the attributes of the current file are displayed​. ls [pattern...] List files in the current DF​. If no pattern is given, then all files are listed​. If one or more patterns are given, only files matching at least one pattern are listed​. find [start−id [end−id]] Find all files in the current DF​. Files are found by selecting all file identifiers in the range from start−fid to end−fid​. If not given, the default value for start−fid is 0000, while the default for end−fid is FFFF​. find_tags [start−tag [end−tag]] Find all tags of data objects in the current context​. Tags are found by using GET DATA in the range from from start−tag to end−tag​. If not given, the default value for start−tag is 0000, while the default for end−tag is FFFF​. mkdir file−id size Create a DF​. file−id specifies the numeric id, and size the size of the DF to create​. pin_info key−typekey−id Get information on a PIN or key from the card, where key−type can be one of CHV, KEY, AUT or PRO​. key−id is a number representing the key or PIN reference​. put file−id input Copy a local file to the card​. The local file is specified by input while the card file is specified by file−id​. quit Exit the program​. random count [output−file] Generate count bytes of random data​. If output−file is given, write the data to the host computer's file denoted by it, otherwise show the data as hex dump​. rm file−id Remove the EF or DF specified by file−id​. unblock CHVpin−ref [puk [new−pin]] Unblock the PIN denoted by pin−ref using the PUK puk, and potentially change its value to new−pin​. puk and new−pin can be sequences of hexadecimal values, strings enclosed in double quotes ("​.​.​."), empty (""), or absent​. If absent, the values are read from the card reader's pin pad​. Examples: unblock CHV2 00:00:00:00:00:00 "foobar" Unblock PIN CHV2 using PUK 00:00:00:00:00:00 and set it to the new value foobar​. unblock CHV2 00:00:00:00:00:00 "" Unblock PIN CHV2 using PUK 00:00:00:00:00:00 keeping the old value​. unblock CHV2 "" "foobar" Set new value of PIN CHV2 to foobar​. unblock CHV2 00:00:00:00:00:00 Unblock PIN CHV2 using PUK 00:00:00:00:00:00​. The new PIN value is prompted by pinpad​. unblock CHV2 "" Set PIN CHV2​. The new PIN value is prompted by pinpad​. unblock CHV2 Unblock PIN CHV2​. The unblock code and new PIN value are prompted by pinpad​. update_binary file−id offs data Binary update of the file specified by file−id with the literal data data starting from offset specified by offs​. data can be supplied as a sequence of hexadecimal values or as a string enclosed in double quotes ("​.​.​.")​. update_record file−id rec−nr rec−offs data Update record specified by rec−nr of the file specified by file−id with the literal data data starting from offset specified by rec−offs​. data can be supplied as a sequence of hexadecimal values or as a string enclosed in double quotes ("​.​.​.")​. verify key−typekey−id [key] Present a PIN or key to the card, where key−type can be one of CHV, KEY, AUT or PRO​. key−id is a number representing the key or PIN reference​. key is the key or PIN to be verified, formatted as a colon−separated sequence of hexadecimal values or a string enclosed in double quotes ("​.​.​.")​. If key is omitted, the exact action depends on the card reader's features: if the card readers supports PIN input via a pin pad, then the PIN will be verified using the card reader's pin pad​. If the card reader does not support PIN input, then the PIN will be asked interactively​. Examples: verify CHV2 31:32:33:34:00:00:00:00 Verify CHV2 using the hex value 31:32:33:34:00:00:00:00 verify CHV1 "secret" Verify CHV1 using the string value secret​. verify KEY2 Verify KEY2, get the value from the card reader's pin pad​. sm {open | close} Call the card's open or close Secure Messaging handler​.
