Re: Cryptsetup re-encrypt with SHA-512 ?

[Sreyan Chakravarty <sreyan32@xxxxxxxxx>]

cryptsetup reencrypt --hash sha512 /dev/sdx 

This works but it will re-encrypt the entire device.

Is it possible to re-encrypt a partition with the

command, to use the SHA-512 hash ?

Currently, my partition uses SHA-256, so I want to reencrypt without losing any data. I have heard that the cryptsetup reencrypt does online re-encryption, but the man page is not clear about how you can introduce a new hash.

Is it even possible ?
