Hi Folks,
Following this discussion I've realized I don't know how to determine
whether a password is encrypted with DES or MD5.
Can someone shed some light on how to do this?
Thanks,
Grant

I believe that it depends upon what library /usr/lib/libcrypt.so is
symlinked to at the time the password is set.

yes, it worked! maybe you are right... I read the passwd man page and
notice that passwd "read" the login.conf file where its writen:
...
default:\
:passwd_format=md5:\
...
thanks
