Please help this newbie

[heather]

Im not quite sure, but i think something missing.

How did you get the IV and hash from a cloudstorage? is there any export function? if yes, how can you export these data without primary signin in?

some other aspects like iterations are also not mentioned, i dont think that you have all the data you need to crack these password

Thanks for responding.  The cloudstorage is "open source" program set up by family member, and we have access to the  hash and "source code" of the program.   The iterations is 1,000.
