HDD FDE is available from all HDD vendors using the OPAL and Enterprise standards via the [[Trusted Computing Group]].<ref>[https://www.trustedcomputinggroup.org/ Trusted Computing Group: Home<!-- Bot generated title -->]</ref> [[Key management]] takes place within the hard disk controller and encryption keys are 128 or 256 [[Binary digit|bit]] [[Advanced Encryption Standard]] keys.
