# kSecOAEPEncodingParametersAttributeName

The OAEP encoding parameters.

## Declaration

```swift
let kSecOAEPEncodingParametersAttributeName: CFString
```

## Discussion

Discussion Set this value to a CFData object when the kSecPaddingKey attribute is set to kSecPaddingOAEPKey. If you don’t set this attribute, a zero length data object is used by default. This attribute is ignored when padding is not set to OAEP.
