Password is used to encrypt full traffic
between local and remote wodVPN peer using AES128 cipher. Both sides
must use same password for successful connection. It is never actually
shown on the network, but no one that doesn't know the password will be
able to hijack your connection.
If wrong password is used, you will not be able to establish
connection with remote side at all. You can leave password property
empty, in which case data isn't encrypted at all. Password cannot be
changed during connection lifetime. If you wish to change it, use
Stop method, make the password
change, and then Start wodVPN
again.
