# Cupcake
Cupcake is an efficient Rust library for the (additive version of) Fan-Vercauteren homomorphic encryption scheme, offering capabilities to
encrypt vectors, add/subtract two encrypted vectors, and rerandomize a ciphertext.
## Requirements
Cupcake requires or works with
* Mac OS X or Linux
## Installation
Add the following line to the dependencies of your Cargo.toml:
```
Cupcake = "0.2.1"
```
## Building from source
```bash
git clone https://github.com/facebookresearch/Cupcake
cd cupcake
cargo build --release
```
## Examples
Several examples are included in `examples/.rs`, and can be run via
`cargo run --example `
## Documentation
Documentation on the API can be built from `cargo doc`.
## Benchmarks and Tests
We have included benchmarks and tests for both homomorphic operations and underlying arithmetic operations. They can be run using `cargo bench` and `cargo test`.
## Supported parameters
Currently, we provide only one set of secure parameter, namely `FV::::default_2048();`. This parameter set has an estimated security level of about 128 bits according
to the homomorphic encryption security standards [link](http://homomorphicencryption.org/wp-content/uploads/2018/11/HomomorphicEncryptionStandardv1.1.pdf). Use other parameters at your own risk! With the default parameter set, the plaintext type is vector of `u8` with a fixed length 2048.
