Encrypt Everything Everywhere (E3)

E³ (Encrypt-Everything-Everywhere) is an easy-to-use open-source homomorphic encryption framework developed by the MoMA Lab at New York University Abu Dhabi. The framework provides C++ classes for supporting computation on private data. E³ is usability-oriented, allowing programmers to incorporate privacy to their programs without expertise in cryptography.

In its first version, E³ encrypts variables using Fully Homomorphic Encryption and provides a rich set of C++ operators to the programmer.

To get started, take a look at the Introduction section to learn more about the framework.

If you use our framework, please cite our paper titled "E³: A Framework for Compiling C++ Programs with Encrypted Operands", which can be found here: https://eprint.iacr.org/2018/1013. The paper describes the process of using E³, as well as how to add new libraries to the framework.
