SSL Certificate FAQs

SSL certificates are a great medium to solve issues of threat, spying, sniffing, and phishing activities as they authenticate and protect ongoing information between two ends (user browser and web server). However, many newbies have little knowledge about SSL practices, so keeping this in mind, we have listed FAQs (Frequently Asked Questions) that generally strike an individual’s mind when anyone wants to know about SSL certificates.

What is SSL?

SSL (secure socket layer) is a protocol designed to protect online information over the web. Encryption technology works on public key infrastructure (public and private key). SSLv3.0 was in practice but deprecated in 2015 due to vulnerability, and TLS was introduced. TLS1.0, TLS1.1, TLS1.2, and TLS1.3 versions have been in practice. The current version is TLS1.3 which was published in 2018.
