cryptsetup reencrypt help...

Hey guys, I just ran this command;

sudo cryptsetup reencrypt --hash whirlpool /dev/nvme0n1p2

and i am wondering what exactly I have just done... I am trying to change the hash function being used to whirlpool but without the other options being specified in this command, will they all be reset to their defaults? IE. aes-xts cipher, and etc?

Thanks.

Re: cryptsetup reencrypt help...

Okay so I ran that and it only changed the hash function, for anybody interested. Now i have one more question...

I am trying to run

sudo cryptsetup reencrypt --cipher aes-xts-plain64 --key-size 512 --hash sha256 --iter-time 4000 --use-random /dev/nvme0n1p2

and it is telling me that:

cryptsetup: Option --use-[u]random is allowed only for luksFormat.

How can I have this working, please?

Thank you...
