From time to time I need to forward forms encrypted to third parties and my usual app would be to use 7Zip to zip it with password and then forward the password separately. In some cases I may use Dropbox with a shared folder. Any other suggestions on either a program for file encryption or some means to send a file securely. Some parties will not accept anything to download from a website or wish to install another program. What would be the easiest and most convenient way to do that now leaving the file contents still safe?
