OPENSC-TOOL(1)

✨ NAME ✨

okay so bestie, meet opensc-tool β€” it's the generic smart card utility from the OpenSC Tools manual (yes, that's section 1, the command-line girlies section πŸ’…). it's your little multitool for poking at smart cards from the terminal.


🌸 SYNOPSIS 🌸

opensc-tool [OPTIONS]

that's it. that's the whole vibe. you just run it with options and it does stuff. iconic.


πŸ¦‹ DESCRIPTION πŸ¦‹

so opensc-tool is the utility you call from the command line when you want to do miscellaneous smart card operations. we're talking getting the card ATR, sending arbitrary APDU commands to a card β€” the little everyday tasks, y'know? nothing dramatic, just your basic card-whispering. no cap, it's genuinely useful 🫢


πŸ’– OPTIONS πŸ’–

  • --version β€” prints the OpenSC package release version. like, which version of OpenSC are we even on rn? this tells you ✨
  • --atr, -a β€” prints the Answer To Reset (ATR) of the card. the output comes out in hex byte format, bestie πŸ”₯
  • *--card-driver *driver, -c driver β€” use the given card driver. the default is to auto-detect the correct card driver (she's independent, she figures it out herself). and if you pass the literal value ? it lists all available card drivers for you πŸ‘‘
  • --list-algorithms β€” lists algorithms supported by card. yes, this one's got a trailing comma in the original, we don't question it, we respect it πŸ’€
  • --info, -i β€” prints information about OpenSC, such as version and enabled components. the little self-intro moment πŸŽ€
  • --list-drivers, -D β€” lists all installed card drivers. all of them. the whole roster 🌈
  • --list-files, -f β€” recursively lists all files stored on card. recursive!! she goes deep 🌸
  • --list-readers, -l β€” lists all configured readers. who's plugged in? let's find out πŸ’œ
  • --name, -n β€” prints the name of the inserted card (driver). name check!! ⭐
  • *--get-conf-entry *conf, -G conf β€” gets a configuration key. the format is: section:name:key
  • *--set-conf-entry *conf, -S conf β€” sets a configuration key. the format is: section:name:key:value
  • *--reader *arg, -r arg β€” the number of the reader to use. by default, the first reader with a present card is used. and if arg is an ATR, then the reader with a matching card gets chosen instead 🫢
  • *--reset [type*] β€” resets the card in reader. the default reset type is cold, but a warm reset is also possible. pick your temperature bestie 🧊πŸ”₯
  • *--send-apdu *apdu, -s apdu β€” sends an arbitrary APDU to the card in the format AA:BB:CC:DD:EE:FF.... use this option multiple times if you wanna send more than one APDU, she's flexible like that.
⚠️ heads up bestie: the built-in card drivers may send additional APDUs for detection and initialization. to avoid this behavior, you may additionally specify --card-driver default. don't get caught off guard by extra APDUs showing up uninvited πŸ™ˆ
  • --serial β€” prints the card serial number (normally the ICCSN). output is in hex byte format πŸ’…
  • --verbose, -v β€” causes opensc-tool to be more verbose. specify this flag several times to enable debug output in the opensc library. the more times you say it, the louder she gets πŸ“’
  • --wait, -w β€” waits for a card to be inserted. patient queen energy, she'll just stand there until a card shows up ⏳
