## Component format

The purpose of this component is to load keys from a local directory.

The component accepts as input the name of a folder, and loads keys from there. Each key is in its own file, and when users request a key with a given name, Dapr loads the file with that name.

Supported file formats:

- PEM with public and private keys (supports: PKCS#1, PKCS#8, PKIX)
- JSON Web Key (JWK) containing a public, private, or symmetric key
- Raw key data for symmetric keys

{{% alert title="Note" color="primary" %}}
This component uses the cryptographic engine in Dapr to perform operations. Although keys are never exposed to your application, Dapr has access to the raw key material.

A Dapr `crypto.yaml` component file has the following structure:

```yaml
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: mycrypto
spec:
  type: crypto.dapr.localstorage
  metadata:
    version: v1
    - name: path
      value: /path/to/folder/
```

{{% alert title="Warning" color="warning" %}}
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets, as described [here]({{< ref component-secrets.md >}}).

## Spec metadata fields

| Field              | Required | Details | Example |
|--------------------|:--------:|---------|---------|
| `path`             | Y        | Folder containing the keys to be loaded. When loading a key, the name of the key will be used as name of the file in this folder.  | `/path/to/folder` |

**Example**

Let's say you've set `path=/mnt/keys`, which contains the following files:

- `/mnt/keys/mykey1.pem`
- `/mnt/keys/mykey2`

When using the component, you can reference the keys as `mykey1.pm` and `mykey2`.
