How do SSL certificates work?

SSL certificates provide a secure connection between client and server by encrypting communications end-to-end. Data is encrypted with the certificate, and decrypted with the proper cryptographic key.

An SSL certificate gives a level of trust and authenticity in the website you’re visiting, and is widely used for all kinds of websites especially business websites and eCommerce websites.

Each certificate contains the following information:

  • Certificate owner’s name
  • Certificate serial number and expiration date
  • Copy of the certificate owner’s public key
  • Digital signature of Certificate Authority (CA)
