box will display the machine ID of the user's
computer. The user can send his/her own machine ID to
you, and you can create a Read Password based on the
user's machine ID. After that the user can use this
Read Password to open your file on his/her computer.

machine ID, the user will not be able to share the
Read Password with other users, the user will not be
able to re-distribute your files;
