I’d like to store encrypted data on an external hard drive plugged to a Rapberry pi. For the moment, only my rootfs is crypted and secured via Zymkey.
I found a python script create_zk_crypt_vol which seems to be out of date.
I’d like the encryption key to be the same as the one used to crypt the root fs on the SD card and mount it once the system is booted.
How can I do that?
