 Please see the attached file.
 This is an example configuration for the background encyption.

 This configuration is 'defconfig'-sytled.
 You should modify the 'storage' section in your defconfig,
 that exists at root of the source code tree, using the example.
 Especilly you must adjust the 'data_lba', 'keys', 'lba-low' and
 'lba-high' parameters for your environment.
 Then you can rebuild bitvisor.elf with the modified defconfig.

 You cannot use the boot/login-simple and the boot/login
 if you want to validate 'defconfig' since bitvisor.conf overwrites
 the whole parameters defined by defconfig.
 If you would like to use the login authentication, you can try to
 rewrite the example for bitvisor.conf.
 Unfortunately I have never tried to enable/configure the
 background encyption with bitvisor.conf, but it must work.

 Thanks,
