Yes, it will totally disconnect your machine from the network and shut 
down ssh just to be sure.

..... o.O

No, it just manipulates text files.

Maybe you should be doing some independent research as to how the 
password files and pam works first.  I'd hate for you to find out that 
some other service you are using breaks because it suddenly can't 
authenticate users.  I mean, why in the world was the machine installed 
in the first place without md5 passwords?  Do you have a local service 
that authenticates directly off the password (shadow) file which doesn't 
understand md5/crypt?  This isn't unheard of.  Back in the day, radiusd 
was fun like that.

Those are questions that you should ask yourself.  I'm not looking for 
an answer, simply giving you a direction.
