OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitate their use in security applications such as authentication, mail encryption and digital signatures. OpenSC implements the standard APIs to smart cards, e.g. PKCS#11 API, Windows’ Smart Card Minidriver and macOS CryptoTokenKit.

OpenSC effort consists of various sub-projects that can be used independently as well, without OpenSC:
- libp11 is a wrapper library for PKCS#11 modules with OpenSSL interface
- pkcs11-helper is a wrapper library for PKCS#11 modules with extended callback mechanisms for user and token interaction
- PAM-PKCS#11 is a feature rich plugable authentication module (PAM) for authentication via PKCS#11 modules, which includes various tools to controls the login process
- pam_p11 is a simple plugable authentication module (PAM) for authentication via PKCS#11 modules
- OpenCT implements a reader driver interface for various non-standard readers on Linux
- OpenSC-Java is a Java PKCS#11 wrapper and JCE Provider
