# secureUnarchiveFromDataTransformerName

The name of the value transformer that creates then returns an object by attempting to unarchive the data to a class that supports secure coding.

```
static let secureUnarchiveFromDataTransformerName: NSValueTransformerName
```

## Discussion

The transformer this property references returns the [`NSData`](/documentation/Foundation/NSData) instance created by archiving the value using secure keyed archiving. This transformer requires that an object implement the [`NSSecureCoding`](/documentation/Foundation/NSSecureCoding) protocol in order to archive and unarchive with this transformer.
