## What it is
Lattigo is a pure Go library implementing lattice-based (RLWE) homomorphic encryption schemes such as BFV/BGV and CKKS, along with their multiparty variants. It enables computation on encrypted data in distributed systems and microservices, with WASM support for browser clients.

## Use cases
- perform computations on encrypted data without decrypting it
- implement secure multiparty computation protocols in Go
- encrypt numeric data with CKKS for privacy-preserving machine learning inference
- build privacy-preserving distributed systems and microservices
- run homomorphic encryption in the browser via WASM
- generate RLWE keys and ciphertexts for lattice-based cryptography research

## When to choose
- your stack is Go and you need homomorphic encryption
- you need multiparty (threshold) homomorphic encryption
- you need cross-platform or WASM builds of HE primitives
- you want performance comparable to C++ HE libraries without cgo

## When to avoid
- you need a non-Go language binding or C++ ecosystem tooling
- you need fully homomorphic encryption with bootstrapping beyond the supported schemes
- you need general-purpose secure computation beyond RLWE-based HE
- your project requires FHE schemes like TFHE with programmable bootstrapping
