opensc: opensc (SmartCard utilities/libraries for PKCS#11/15 compatible cards) opensc: opensc: It provides a set of libraries and utilities to access smart cards. Its opensc: main focus is on cards that support cryptographic operations, and opensc: facilitate their use in security applications such as mail encryption, opensc: authentication, and digital signature. OpenSC implements the PKCS#11 opensc: API so applications supporting this API such as Mozilla Firefox and opensc: Thunderbird can use it. OpenSC implements the PKCS#15 standard and aims opensc: to be compatible with every software that does so, too. opensc: opensc: Homepage: http://www.opensc-project.org/opensc/
