## What it is
TFHE-rs is a pure Rust implementation of the TFHE fully homomorphic encryption scheme, enabling boolean and integer arithmetic over encrypted data. It provides a Rust API, C bindings, and a client-side WASM/JavaScript API, with features like programmable bootstrapping and ciphertext compression.

## Use cases
- compute on encrypted data without decrypting it
- perform boolean logic on encrypted bits
- do arithmetic on encrypted integers up to 8 bits
- build privacy-preserving applications with FHE in Rust
- use homomorphic encryption from C or JavaScript via WASM
- research and experiment with TFHE programmable bootstrapping

## When to choose
- you need fully homomorphic encryption for boolean or short integer computation
- you want a high-performance, production-oriented FHE library in Rust
- you need client-side encryption with a WASM/JavaScript API
- you want ciphertext and server key compression for efficient transfer

## When to avoid
- you need general-purpose FHE over arbitrary data types or machine learning workloads (consider other Zama libraries like Concrete or Concrete-ML)
- you need fast computation - FHE has large performance overheads compared to plaintext
- you need a lightweight encryption scheme without homomorphic properties

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security, sdk
- domain: security, privacy, developer-tools
- platform: rust, cpp, c, wasm, cross-platform
