What os are you using?

I have seen on some systems a * means an invalid password exists.
Code:
Examples
Typical records that show an invalid password for smith and guest follow: 

smith:*:100:100:8A-74(office):/home/smith:/usr/bin/sh
guest:*:200:0::/home/guest:/usr/bin/sh  

The fields are in the following order: user name, password, user ID, primary group, general (gecos) information, home directory, and initial program (login shell). The * (asterisk) in the password field indicates that the password is invalid. Each attribute is separated by a : (colon). 

If the password for smith in the previous example is changed to a valid password, the record will change to the following: 

smith:!:100:100:8A-74(office):/home/smith:/usr/bin/sh 

The ! (exclamation point) indicates that an encrypted password is stored in the /etc/security/passwd file.

That x or * means that the encrypted password has been moved from /etc/passwd to /etc/shadow. It means the password has been "shadowed", not "encrypted".
