OpenSC is a library for accessing SmartCard devices. It is also
the core library of the OpenSC project.
Basic functionality (e.g. SELECT FILE, READ BINARY) should work on
any ISO 7816-4 compatible SmartCard. Encryption and decryption
using private keys on the SmartCard is possible with PKCS #15
compatible cards, such as the FINEID (Finnish Electronic IDentity)
