Lime2-server : Encrypt SATA system HDD

[oly]

Hi,

Using this informations, I used the latest Olimage (A20-OLinuXino-bullseye-minimal-20211130-145129) on my Lime2-server.
Then I used the olinuxino-sd-to-sata script with succes.

Now I would like to encrypt the SATA HDD.

I found this old tutorial but seems tricky ... and I'm not sure it would match my context.

What is the best way to achieve that ?
