SSL Certificate Frequently asked questions

What happens when a computer connects to an authenticated website?

  • The browser will ask the website to provide information to confirm the customer's identity.
  • The website will send the browser its previously issued SSL certificate.
  • The browser will check if the SSL certificate is real or not. If it is, it will notify your website that the SSL has been accepted.
  • The website will send back digits for encryption and decryption during Internet transactions.
  • The data between the website and the browser is successfully encrypted.

What does the browser do to check if an SSL is real or not?

  • When a website sends the browser an SSL certificate, the browser sends them to a server that hosts the approved digital certificates. Technically, SSL uses public key encryption to help the website and the browser negotiate a set of keys to use throughout the information exchange process.
  • In the next transaction, the key set will be changed. Another person will not be able to decrypt it even if it has the data of the server hosting the SSL certificate.

What does SSL/TLS have to do with HTTPS?

  • When setting up a website's security certificate, you need to configure it to transmit data over https. These two technologies often go hand in hand and you cannot use either one. Urls uses either http (Hypertext Transfer Protocol) or https (Hypertext Transfer Protocol Secure). These protocols determine how much data is transmitted and recorded.
