We present and demo of Lattigo, a multiparty homomorphic encryption library in Go. After a brief introduction of the origin and history of the library, we dive into the most relevant technical aspects that differentiate Lattigo from other existing libraries. From the cryptographic research perspective, we describe our realization of the keyswitch and CKKS bootstrapping operations. We also present our approach to multiparty homomorphic encryption and its importance for Lattigo use-cases. From the software perspective, we elaborate on the choice of the Go language and the benefits it brings to application developers who use the library. We then present performance benchmarks and the main use-case applications the library had so far. The last part of the presentation comprises a tutorial on how to use Lattigo to build a" toy" use-case: a privacy-preserving web-application for scheduling meetings.
