# evm-signer

The `evm-signer/` package contains libraries for signing messages and transactions with hardware security modules (HSMs).
At this time, only GCP KMS-managed HSMs are supported, but we hope to add support for AWS Cloud HSM, Azure Dedicated HSM, and self-hosted HSMs.

## Prerequisites
We'll assume that you've set up a Google Cloud account and created an HSM key with Purpose `Asymmetric sign` and with Algorithm `Elliptic Curve secp256k1 - SHA256 Digest`.

You'll need to set appropriate `GOOGLE_APPLICATION_CREDENTIALS` for submitting requests.
The easiest way is to create a service account with the `roles/cloudkms.signer` and `roles/cloudkms.publicKeyViewer` minimum permission set.

You should add a new JSON key to your service account, and download it. Then set

```sh
$ export GOOGLE_APPLICATION_CREDENTIALS=key.json
```

pointing to the downloaded keyfile.

## Installing

You can install with npm:

```sh
$ npm install @dropyacht/evm-signer
```
