SSL certificates help keep customer information safe, authenticate websites, and offer safe web transactions. After the browser verifies the CA and the certificate, it assures the users that the website is safe. The browser and the web server establish a connection through an SSL handshake by encrypting and decrypting public and private keys, thereby creating a session key to encrypt all the transmitted data. An SSL certificate includes three main entities-a public key, a private key, and the subject (which can be the name of the certificate or of the domain). The digital certificate that enables identity authentication and ensures that the connection is encrypted is known as an SSL/TLS certificate. The CA will verify your signature using the public key and will verify your identity, after which you'll be provided with a digital certificate. This certificate is a data file containing the identity credentials of websites, people, or devices, and it acts as its online identity proof. To obtain a digital certificate for your site, you can raise a request to any CA with your distinguished name, public key, and signature. A CA is a trusted authority that verifies the sites that are available online to ensure safe and transparent digital interaction. The lock icon on a website, the green address bar, and the HTTPS at the beginning of a link are extended validation indicators that indicate the website is SSL or TLS secured.Ī certificate authority (CA) will issue an SSL certificate to a website or a domain to certify that a trusted third party has verified the site's authenticity.

SSL is a security protocol that creates an encrypted connection between the server and the client. You need a valid Secure Sockets Layer (SSL) certificate to secure your online presence. To offer a secure and reliable service, you need to identify loopholes, implement preventive measures to thwart attacks, and ensure customer data privacy.
