iv is optional here, but I have tried with 32 byte hex string as well.
It always return invalid result, anyone have idea why it fails?
@sagarHexa, I tried to get this moved to the developer section where it belongs, but, as usual, the moderators are ignoring my report.
You don't have enough hex bytes in your key. A "hex byte" is two characters from 00 to FF. You need 32 of them (or 64 characters total) and I don't know what it does with letters like the y you have in your key.
