## Verifying Artifacts

We sign our artifacts using this [key][signing_key]:

```
pub rsa4096/dbd744ace7ade6aa50dd591f66b50994442d2d40 2021-07-09T14:50:19Z
	 Hash=a79b48fd6a1f31699c788b50c97d0b98

uid Square Clippy <opensource@squareup.com>
sig  sig  66b50994442d2d40 2021-07-09T14:50:19Z 2041-07-04T14:50:19Z ____________________ [selfsig]
```

The best way to verify artifacts is [automatically with Gradle][gradle_verification].
