Please note, I am new to ubuntu system and need some help.

My /etc/passwd and /etc/shadow files have the following details:

  • /etc/passwd:

    root:x:0:0:Super-User:/:bin/sh

  • /etc/shadow:

    root:giPrt.M0Q66Yc:1:0:99999::::

I understand that the passwd file has the root password set to x which means it is encrypted as listed in shadow file. But the root password in the shadow file has a different format compared to the following format:

  • $1$ is MD5,
  • $2a$ is Blowfish,
  • $2y$ is Blowfish,
  • $5$ is SHA-256,
  • $6$ is SHA-512,
  • $y$ is yescrypt,

So, my question is, is my password stored as plain text "giPrt" in the shadow file and what is "M0Q66Yc"?

No passwords are stored in plain text anywhere on your system. All passwords in /etc/shadow are hashed (not encrypted).

Note that a stock install of Ubuntu from an install iso has the root account disabled, and it has no password at all. Best practice is to leave it that way.
