Welcome to SCAPI

SCAPI is an open-source Java library for implementing secure two-party and multiparty computation protocols (SCAPI stands for the “Secure Computation API”). It provides a reliable, efficient, and highly flexible cryptographic infrastructure. SCAPI also has a c++ version - currently in beta. SCAPI is free and is licensed under an adaptation of the MIT license, you can read more about the license here.
