Hi Gilad,

Thank you for testing it. Do you have access to a device having crypto
hardware with IV generation capability and associated drivers for let
say, aes with cbc or any another mode? I was wondering if I can customize
it to work with dm-crypt by generating IVs automatically. Please let
me know your thoughts.

Thanks,
Binoy
