This tutorial details the steps involved in implementing a new backend engine utilizing the C++ wrapper for use with the testing framework.

Refer to Glossary for a list of terms that will be mentioned throughout this tutorial.

This guide is intended to be a beginner's guide for people who are looking to get a backend with a single test implemented quickly. It is based on using the api_bridge_example_backend as a starting point for a new backend implementation which uses the C++ wrapper.

For the purposes of this guide, we will be creating a very basic backend implementing a benchmark for the vector element-wise addition workload, under the offline category, with first operand in plain text and second encrypted.

Select your preferred library below. The tutorial will follow up using that library to perform Homomorphic Encryption (HE) operations.
