libp11 is a library implementing a thin layer on top of PKCS#11 API to make using PKCS#11 implementations easier.

The official name for PKCS#11 is "RSA Security Inc. PKCS #11 Cryptographic Token Interface (Cryptoki)".

The official header files for PKCS#11 Standard were released under a non-free license. libp11 does not include these header files, but instead uses a rewritten pkcs11.h header file from the Scute project.

libp11 is written by an international team. It is a free software licensed under LGPL license version 2.1 or later:
