NMAOutOfBandPayloadDecode

@objc
public protocol NMAOutOfBandPayloadDecode : NMAOperation

The object that decodes an NMAOutOfBandPayload from a String in JSON format or a Base64 URL encoded {@code String} representing the JSON. The NMAOutOfBandPayload can be used to trigger an out-of-band operation NMAOutOfBandOperation.

Usage example:

id<NMAOutOfBandPayloadDecode> oobPayloadDecode = [[client operations] outOfBandPayloadDecode];
[oobPayloadDecode json:jsonPushNotification]];
[oobPayloadDecode onSuccess:^(NMAOutOfBandPayload * _Nonnull oobPayload) {
    // Payload is returned by the SDK.
}];
[oobPayloadDecode onError:^(NMAOutOfBandPayloadError * _Nonnull error) {...}];
[oobPayloadDecode execute];

The JSON is obtained from a push notification, or as a Base64 URL encoded JSON in QR codes generated by the server. JSON example:

{
    "nma_data" : {
        "token" : "b4b07559-f934-4597-a1c5-44d89f691e8f",
        "redeem_url" : "https://fido.siven.ch/nevisfido/token/redeem/authentication",
        "attributeName" : "some additional data to be included in the QR code"
    },
    "nma_data_content_type" : "application/json",
    "nma_data_version" : "1"
}
