This works for ksh93 and should be easily modifable for bash.
Code:
passwd=""
omodes=`stty -g`

echo "Enter Password: \c"
while :
do
   stty raw
   c=$(dd bs=1 count=1 2>/dev/null)
   stty -raw

   # break out of loop if CR found
   [[ -z $(echo $c | tr -d "\015") ]] && break

   stty echo
   echo "*\c"
   passwd=${passwd}${c}
   stty -echo
done

stty $omodes

echo
echo "Password entered: $passwd"

NAME

       sim, SIM - Software phrase input method

DESCRIPTION

       The  phrase  input  method is an input method that is commonly used in a Chinese environment. The software phrase input method (SIM) is a a
       mechanism supported by the Asian tty driver, atty and the simd daemon through the utx facility (see atty(7), simd(8), and utx(7)).

       The stty command activates the software phrase input method, while the phrase utility creates and manages the phrase database (see  stty(1)
       and phrase(1)).

       Changes	to  the phrase database may not be reflected in SIM sessions that were started before the changes were made. Therefore, users have
       to stop and then restart SIM sessions using the stty command to have access to the changed phrase database.

SEE ALSO

       Commands: phrase(1), stty(1), simd(8), utxd(8)

       Files: atty(7), utx(7)
