I want to encrypt my website

I want to encrypt my full website. For more details, I am giving exact thing and details for that:- At first, I want to say that I want to encrypt following:- 1. Database of WordPress ( That stored User id, password, email, checkout information, etc) 2. URL encryption ( I want to encrypt the URL so that user can not see the exact the URL) 3. Content Encryption ( I want to encrypt the content of the website so that the user can not see the source by view-source: Website Url) 4. Api encryption ( I have two sensitive API that contents "API key" and "API secret". I want to hide those text so that If anyone gets access then they can not see the actual one) Why do I want to? In this time, Many websites are hacked instead of they create strong passwords. So I want to secure the website as I have two sensitive information in API that I told above. The system can only decrypt it. The APIs are for SMS or Payment gateway. The next thing that I am collecting the sensitive information of users like password, Name, Phone number, Email Id, and more. Wordpress only stores the password in the database with the encrypted format. So If anyone gets access to it, he can get all information. I have an SSL by siteground that also I have installed. But I also collected some sensitive information during checkout. So I want to encrypt it all as well as the content. I think you have understand the reason why I want to do and what to do. If you have more ideas for security you may share with me. Actually I have done many simple basic steps for secure my website. Let me know how many days you need to do it. I have a time of the week. I am waiting for the project estimated and time details form you.
