Does Linux know if my passwords are similar?

On my Linux machine, I'm trying to change the user password but when I tried to keep it similar to the old one, Linux said that they were too close. But how would Linux know that? Isn't the password saved as a hash?

    It knows it because you typed your old password in order to logon to the session in the first place. It has to have the plain-text version in order to hash it before comparing against the password file. This is completely separate from the hashed version and is only available in the active session.
