SSL certificate has been described as “Saving the internet, one green lock at a time.” Having the little green padlock from a trusted SSL certificate issuer give more confidence to your clients to deal with you. If you don’t have the green lock, most browsers will tag your site as Not Secure.
An SSL certificate creates a secure tunnel through which information including usernames, passwords, credit card numbers and more can pass safely.
When a visitor enters an SSL-protected website, your SSL certificate automatically creates a secure, encrypted connection with their browser.
Once the connection is complete, a padlock icon and https:// prefix appear in the visitor’s browser bar to show them they are safe to share personal details, and that their data is virtually un-hackable.
It was the understanding the need to keep all websites secured that led to the “Let’s Encrypt SSL” initiative.
Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. It is a service provided by the Internet Security Research Group (ISRG).
The organisation gives the digital certificates to enable HTTPS (SSL/TLS) for websites, for free, in the most user-friendly way. The whole essence is to create a more secure and privacy-respecting web.
