# Decentraland crypto (Rust)

This crate is a port of [`@dcl/crypto`](https://github.com/decentraland/decentraland-crypto)
originally implemented on javascript and provides the necessary tools to create and validate
Decentraland's Authentication Chains.

## Test

To run all tests you need to provide a ethereum rpc endpoint.

First, create a `.cargo/config.toml` file using the template provided in the repository and set your rpc provider.

```bash
cp .cargo/config.toml.example .cargo/config.toml
```

Once configured you can run all tests

```bash
cargo test --doc
```
