# [node-seal](https://github.com/s0l0ist/node-seal) · [](https://github.com/s0l0ist/node-seal/blob/main/LICENSE) [](https://codecov.io/gh/s0l0ist/node-seal) [](https://www.npmjs.com/package/node-seal) [](https://app.fossa.com/projects/git%2Bgithub.com%2Fs0l0ist%2Fnode-seal?ref=badge_shield&issueType=license)
node-seal is a homomorphic encryption library for TypeScript or JavaScript.
- **Web Assembly:** Fastest web implementation of the C++ [Microsoft
SEAL](https://github.com/microsoft/SEAL) library
- **Zero dependencies:** Very lean, only contains a low level API which is very
close to the C++ calls from Microsoft SEAL.
- **Node.js, Browser:** Install once, work in any server/client configuration.
**Now supporting Microsoft SEAL 4.1.2**
## Installation
node-seal can be installed with your favorite package manager:
```shell
npm install node-seal
```
```shell
yarn add node-seal
```
Import the library using `import` or `require` syntax:
```javascript
// Auto-detects browser or nodejs.
// Defaults to "node-seal/throws_wasm_node_umd" for NodeJS
// Defaults to "node-seal/throws_wasm_web_umd" for Browsers
// Defaults to "node-seal/throws_wasm_web_es" for Modules
import SEAL from 'node-seal'
const SEAL = require('node-seal')
```
You may also specify a deep import to target your environment better. This is
useful for environments that aren't detected properly or do not support
WebAssembly. In addition, there are two separate bundles for throwing on
transparent ciphertexts and another for allowing transparent ciphertexts. If
you're unsure what you need, start with the build that **throws** on transparent
ciphertexts. This is also the default import that is used.
The deep import link is structured like the following:
`node-seal / _wasm__`
```javascript
// Always Pick a variant which throws on transparent ciphertexts unless you
// have a specific reason to allow the use of transparent ciphertexts.
import SEAL from 'node-seal/throws_wasm_node_umd'
// Or pick a variant which allows transparent ciphertexts (only use this if you know what you're doing)
import SEAL from 'node-seal/allows_wasm_node_umd'
```
#### React-Native
React-native does not support WASM libraries; however, it is possible to run a
WASM library, including `node-seal` by using a
[WebView](https://github.com/react-native-webview/react-native-webview#readme)
to load both the library and a simple interface to communicate with on top of
the built-in `postMessage` API. Instead of publicly hosting the web application
to be rendered by the WebView, it is possible to bundle the mini web application
into a single HTML file (with JS inlined) and load the HTML file directly to the
WebView.
## Demo
Go to the [sandbox](https://s0l0ist.github.io/seal-sandbox/)
This sandbox was built for users to experiment and learn how to use Microsoft
SEAL featuring node-seal.
- **Encryption Parameters:** experiment with many settings to prototype a
context.
- **Keys:** Create, download, upload Secret/Public Keys - even for
Relinearization and Galois Keys.
- **Variables:** Create, download, upload PlainTexts or CipherTexts
- **Functions:** Create a list of HE functions to execute!
- **Code Generation:** After your experimentation is complete, generate working
code to use!
## Usage

## Examples
Check out the [Sandbox](https://s0l0ist.github.io/seal-sandbox/) to run HE functions and even
generate working code!

## Benchmarking
Microsoft SEAL has a native benchmark tool that we compile directly to WASM.
1. `npm run seal:build:bench`
2. `npm run benchmark`
## Performance
Microsoft SEAL now comes with a benchmark binary that can be directly compiled
to WASM. All numbers are measured in `us` and are ran on an arm64 system
Test specs:
- MacBook Pro (14-inch, 2021)
- MacOS Ventura 13.1 (22C65)
- Apple M1 Pro (8 performance and 2 efficiency), 32 GB

## Caveats
Conversion from C++ to Web Assembly has some limitations:
- **±2^53 bit numbers:** JavaScript uses 2^53 numbers (not true 64 bit). This
means we lose some precision after cryptographic operations are computed in
WASM and we want to send the results to JS for consumption (across the WASM <>
JS boundary). If you're using the `CKKS` scheme, you need to keep this in
mind. `BFV` users will inherently adhere to these limitations due to the
Int32Array/Uint32Array TypedArrays. Recently, `BFV` users now have support for
BigInt64Array/BigUint64Array TypedArrays but at a significant encode/decode
penalty - encyption/evaluation/decryption performance is the same.
- **Memory:** Generating large keys and saving them in the browser could be
problematic. We can control NodeJS heap size, but not inside a user's browser.
Saving keys is very memory intensive especially for `polyModulusDegrees`s
above `16384`. This is because there's currently no way (that we have found)
to use io streams across JS and Web Assembly code, so the strings have to be
buffered completely in RAM and they can be very, very large when using the
default `zstd` compression. User's who are experiencing OOM exceptions when
saving `GaloisKeys` should try specifying a compression override such as
`none` or the less performant `zlib`. Ex:
`galoisKeys.save(seal.ComprModeType.zlib)`
- **Garbage Collection:** Unfortunately, the typical way of cleaning up
dereferenced JS objects will leave behind a the Web Assembly (C++) object in
memory. There is no way to automatically call the destructors on C++ objects.
JavaScript code must explicitly delete any C++ object handles it has received,
or the heap will grow indefinitely.
```javascript
.delete()
```
