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.

The latest release is 2.4.0 and can be found here. Alternately you can simply clone the repository to get the latest and greatest.

Go to http://scapi.readthedocs.org/ for a prebuilt version of the current documentation. Otherwise build them yourself from the sphinx sources in the docs folder.

We also added the javadoc reference under docs/javadoc/ directory, and you can view it online here.

More information about SCAPI and the motivation behind it appears in this paper.

See the documentation for explanations, but if you get stuck we are always happy to help. Email us at scapi@biu.ac.il with any questions you have.

We will be very happy to receive contributions of new code that extends SCAPI (under the condition that it is cleanly written, well documented, and fits into the SCAPI design paradigm).

We also encourage you to open new issues and let us know of any problems you find, or any new features you feel are necessary.
