# integrityAlgorithm

The algorithm used by the Security Association to verify the integrity of data.

## Declaration

```swift
var integrityAlgorithm: NEVPNIKEv2IntegrityAlgorithm { get set }
```

## Discussion

Discussion The default value of this property is NEVPNIKEv2IntegrityAlgorithm.SHA256. The system infers its IKE psedo-random number generation algorithm based on the integrity algorithm.
