## SSH host key fingerprints

When connecting to a dev desktop for the first time, you should verify the
SSH host key fingerprint. The following fingerprints are used by the dev
desktops.

| Machine | ED25519 |
|--------------------|------------------------------------------------------|
| `dev-desktop-eu-1` | `SHA256:QPuC8ODm+no9wjAtrSMCuqj+iGXsFI5ZGR3C+nX7Im0` |
| `dev-desktop-us-1` | `SHA256:UOZn6OKFrCRt+CLPl5fHZd93Tym4ckBrr8rgfgEPT5g` |
| `dev-desktop-eu-2` | `SHA256:biz6c8LJ6cdb6Ku9mlELzl1qh8sODZWtpNfAJPxBi2I` |
| `dev-desktop-us-2` | `SHA256:u6SNCQw++6LV+IhQYEqIcuFo4GIaiU7DyUhaqWEmQdI` |

You can verify the fingerprint by running this script and compare the output with the table above:

```shell
ssh-keygen -lf <(ssh-keyscan -t ed25519 <name>.infra.rust-lang.org 2>/dev/null | grep -v '^#')
```

For convenience, the host keys are also available as `known_hosts` entries:

```text
