OpenSC includes a number of command line tools for exploring smart cards,
testing, automatisation and debugging. The tools are (with links to the online
man pages):
- opensc-tool is the basic test tool. with "-l" you can see the readers, with
"-n" you can see if opensc identifies the card correctly. both is necessary for any other card tool to work.
with commands like ls, get information about files, read and write files and so on. only works on some cards, as not all cards have
the required functionality (for example no "ls"/"dir" command).
- pkcs15-init can erase your smart card, initialize it, create pins and generate keys
and store certificates and keys or complete p12 bundle files.
- pkcs15-tool will show you what is on your card, lets you browse pins, certificates and keys, and lets you unblock and change pins.
- pkcs15-crypt offers access to the crypto functionality, such as signing data or decrypting data.
- pkcs11-tool does all these things too, but uses the opensc PKCS#11 module. as such it works like mozilla and thus is nice for testing. it also has a test mode to check all most operations. pkcs11-tool uses opensc PKCS#11 module by default, but will work well with any other PKCS#11 implementation specified with "--module", too.
- cardos-info prints some information for Siemens CardOS/M4 cards. will not work at all with other cards.
- cryptoflex-tool can help you with cryptoflex cards, will not work with any other card.
- eidenv lets you access the extra data on belgian eid cards, like card holder, photo, etc.
- netkey-tool can help you with tcos cards in netkey format. will not work with any other card.
- piv-tool used to do primative card administration operations on PIV cards. Some vendor's cards may have additional functions not handled by the piv-tool.
- opensc-config was meant to ease developing with opensc, but now we recommend to use pkg-config instead. only provided for backwards compatibility.
