One week ago Google sent me an email to go HTTPS. If I won't transfer HTTP to HTTPS then it will show my connection unsecured to all of my site visitors who will try to input text in my site.Without using SSL, is there any other way to make my connection secured ? As it is related to costly process to use SSL in web URL, I am searching for any other option instead. 
Are there other options besides HTTPS for securing a website to avoid text input warnings in Chrome?
