I have installed my Fedora Workstation version 23 using native disk encryption.
Since it, I am upgrading it using dnf system-upgrade plugin.
Some time ago, I’ve discovered about SHA1 is now discontinued.
Reading the cryptsetup luksDump of my encrypted system, I can see it was installed using SHA1:
Version: 1 Cipher name: aes Cipher mode: xts-plain64 Hash spec: sha1 Payload offset: 4096 MK bits: 512
My password has more than 70 characters. But, should I reinstall the full system to update my hash encryption ?
I am really unsafe for keeping SHA1 ?
