@railgun-community/curve25519-scalarmult-neon v0.1.11

Node.js addon for Curve25519 Scalarmult, written in Rust

Uses the Rust Dalek library to implement a performant scalarmult function.

Installing curve25519-scalarmult-neon

Installing curve25519-scalarmult-neon requires a supported version of Node and Rust.

You can install the project with npm. In the project directory, run:

$ npm install

This fully installs the project, including installing any dependencies and running the build.

Building curve25519-scalarmult-neon

If you have already installed the project and only want to run the build, run:

$ npm run build

This command uses the cargo-cp-artifact utility to run the Rust build and copy the built library into ./index.node.

Available Scripts

In the project directory, you can run:

npm install

Installs the project, including running npm run build.

npm build

Builds the Node addon (index.node) from source.

Additional cargo build arguments may be passed to npm build and npm build-* commands. For example, to enable a cargo feature:

npm run build -- --feature=beetle

npm build-debug

Alias for npm build.

npm build-release

Same as npm build but, builds the module with the release profile. Release builds will compile slower, but run faster.

npm test

Runs the unit tests by calling cargo test. You can learn more about adding tests to your Rust code from the Rust book.

Making prebuilds

For Android

Make sure you have the cross-compilation targets supported:

rustup target add arm-linux-android

rustup target add aarch64-linux-android

rustup target add x86_64-linux-android

Use Android NDK version 24 or higher by ensuring you have the env var ANDROID_NDK_HOME pointed at the NDK 24 directory. If you get a compilation error about -lgcc, you might have to apply this hack deep in your NDK.

npx prebuild-for-nodejs-mobile android-arm --sdk31 --verbose

npx prebuild-for-nodejs-mobile android-arm64 --sdk31 --verbose

npx prebuild-for-nodejs-mobile android-x64 --sdk31 --verbose

For iOS

Make sure you have the cross-compilation targets supported:

rustup target add x86_64-apple-ios

rustup target add aarch64-apple-ios

Then compile the prebuilds:

npx prebuild-for-nodejs-mobile ios-arm64 --verbose

npx prebuild-for-nodejs-mobile ios-x64 --verbose
