Статья

Asynchronously creates an OutputStream for writing protected content.

This method is asynchronous as it may require server client communication.

When publishing content your app is required to call CustomProtectedOutputStream.close after it is finished writing the content to the CustomProtectedOutputStream. If the flush() is not called we cannot guarantee that all the encrypted data is stored to the backing stream.

Signature

public static IAsyncControl create(OutputStream backingOutputStream,
                                       UserPolicy userPolicy,
                                       CreationCallback<CustomProtectedOutputStream> callback)
            throws InvalidParameterException

Parameters
