# ASAuthorizationPublicKeyCredentialPRFAssertionInputValues

The values to use as inputs to the salts for deriving the symmetric key.

```
@interface ASAuthorizationPublicKeyCredentialPRFAssertionInputValues : NSObject
```

## Overview

This type is analogous to `AuthenticationExtensionsPRFValues` in the WebAuthn specification.

## Topics

### Creating an input values instance

[`initWithSaltInput1:saltInput2:`](/documentation/AuthenticationServices/ASAuthorizationPublicKeyCredentialPRFAssertionInputValues/initWithSaltInput1:saltInput2:)

Initializes an input values object with the given salts.

### Accessing salt inputs

[`saltInput1`](/documentation/AuthenticationServices/ASAuthorizationPublicKeyCredentialPRFAssertionInputValues/saltInput1)

A salt for the hashing function.

[`saltInput2`](/documentation/AuthenticationServices/ASAuthorizationPublicKeyCredentialPRFAssertionInputValues/saltInput2)

An optional second salt for the hashing function.
