is my root password encrypted?

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"?
