create-hash(<variable>, type="sha256")
```

## Parameters

| Parameter  | Type   | Required | Description                                                              |

| `type`     | string | Yes      | Hash algorithm: `"sha256"`, `"sha512"`, `"sha1"`, `"md5"`, or `"sha224"` |
| `encoding` | string | No       | Output encoding: `"hex"` (default) or `"base64"`                         |

## Examples

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
create-hash(<variable>, type="sha256")
create-hash(<variable>, type="md5", encoding="base64")
```
