Smart Card Applications

OpenSC comes with a bunch of utilities to test, debug and initialize smartcards. In addition to these smart card targeted utilities other applications can be made 'smartcard aware' using:

• OpenSC PKCS#11 module opensc-pkcs11 (or pkcs11-spy if one has to debug PKCS#11 issues). This is the preferred interface.
• OpenSSL engine - engine_pkcs11 (together with a/the PKCS#11 module) and engine_opensc (deprecated). This can be used in scripts via the openssl utility or existing OpenSSL based applications can be extended to support dynamic openssl engines.
