SSL Certificates are SSL (Secure Sockets Layer) certificates that authenticate websites and allow them to switch from HTTP to HTTPS encryption, protecting the exchange of valuable information visitors send to or receive from a website.
When you’ve got an SSL certificate protecting your site, your customers can rest assured that the information they enter on any secured page is private and can’t be viewed by any bad actors. it easy to install your certificate and protect sensitive customer data on your site.
SSL stands for Secure Sockets Layer, the SSL certificate displays information to verify the owner of a website and encrypting web traffic with SSL/TLS — including the public key, the issuer of the certificate and associated subdomains. And SSL, commonly known as TLS, is a protocol for encrypting Internet traffic and verifying server identity. All websites with an HTTPS web address uses SSL/TLS.
It's very important that you have an SSL certificate on your site to instill user's trust: you need it to keep user data secure, verify ownership of your website,and to prevent attackers from creating a false version of your site.
Authentication: SSL certificates verify clients that owns the domain. This prevents domain attacks and spoofs.
Encryption: SSL/TLS encryption is possible via the public-and-private key pairing that facilitates SSL certificates. Clients get the public key to open a TLS connection from the server's SSL certificate.
HTTPS: SSL certificates are required for the HTTPS web address. HTTPS (the secure version of HTTP) appear on websites that have traffic encrypted by SSL/TLS. Plus, in addition to securing user data, HTTPS displays a credible "trust factor" from the perspective of the site visitor.
