This type represents the inputs for the WebAuthentication PRF extension, when used during assertion requests.
The PRF extension lets you create general purpose SymmetricKeys from passkeys, which could useful for tasks such as encryption of user data.
The same input values used with the same passkey will always produce the same SymmetricKey.

perCredentialInputValues
TypeScript
get perCredentialInputValues(): (NativeMap<ArrayBuffer, ASAuthorizationPublicKeyCredentialPRFAssertionInput_InputValues>) | null
Swift declaration
let perCredentialInputValues: [Data : ASAuthorizationPublicKeyCredentialPRFAssertionInput.InputValues]?
A map of `credentialID`s to input values for the PRF extension. If the user selects a passkey which matches a `credentialID` in this dictionary, the corresponding input values will be used.
If the selected passkey does not match and `inputValues` is non-nil, that will be used instead. Otherwise, no PRF output will be returned.
When this value is non-empty, the request must specify `allowedCredentials`.
The inputs for the PRF extension, when not specifying general input values.
- Parameter perCredentialInputValues: This dictionary maps `credentialID`s to input values. If the user selects a passkey with a `credentialID` that matches one of these keys, the corresponding input values will be used. If the selected passkey does not match, no PRF result will be returned. When using this option, the dictionary must be non-empty and the request must use `allowedCredentials`.
- Returns: A configured instance of `ASAuthorizationPublicKeyCredentialPRFAssertionInput`.

inputValues
TypeScript
get inputValues(): (ASAuthorizationPublicKeyCredentialPRFAssertionInput_InputValues) | null
Swift declaration
let inputValues: ASAuthorizationPublicKeyCredentialPRFAssertionInput.InputValues?
If specified, the input values to use when generating the PRF extension output.
When also using `perCredentialInputValues`, the corresponding value from that dictionary may be used instead.
The inputs for the PRF extension.
- Parameters:
- inputValues: These are the default inputs that will be used for generating the PRF.
- perCredentialInputValues: This optional dictionary maps `credentialID`s to alternate input values. If the user selects a passkey with a `credentialID` that matches one of these keys, the corresponding input values will be used instead of those from the first argument. When specifying a non-empty value here, the request must use `allowedCredentials`.
- Returns: A configured instance of `ASAuthorizationPublicKeyCredentialPRFAssertionInput`.
