```

## Values

| Name                    | Value | Description                                                                                                                          |
| ----------------------- | ----- | ------------------------------------------------------------------------------------------------------------------------------------ |
| `SignatureFormat.PADES` | `0`   | PAdES / CAdES-detached (`ETSI.CAdES.detached`). This is the default and the format required for the PAdES baseline levels above B-B. |
| `SignatureFormat.CMS`   | `1`   | Classic CMS (`adbe.pkcs7.detached`) — the traditional Adobe signature format.                                                        |

## Usage Example

```python

from nutrient_sdk import SignatureFormat

# Access enum values

value = SignatureFormat.PADES
print(f"Value: {value}")  # Output: Value: SignatureFormat.PADES

print(f"Integer value: {value.value}")  # Output: Integer value: 0

```
