SSL (Secure Sockets Layer) makes an encrypted connection between a web server and a browser. The connection makes sure smooth transmission of confidential and private information without obstacles such as data tampering, data stealing, as well as message forgery.
The certificates work using multiple ways: private keys as well as public keys. The latter is intended to encrypt a connection, whereas the former decrypts or unlocks it. These keys provide an additional layer of privacy to the data of a user from the rest of the internet world. These make users’ message safe from threats, such as hacking to name one. SSL certificates are inarguably the best way out there to keep information secure.
Web hosts provide different types of the certificate, and all of these use the same encryption methods. Each option has its own attributes and requirements. These are equally effective as well as safe.
Single Domain SSL Certificate
As its name implies, the certificate protects one domain name. It is an ideal option for a simple, content-based website. If you have an e-commerce or a normal B2B website, where all transaction takes place on one domain, this certificate will provide you with full security.
Multiple Domain (SAN) SSL
Also known as SAN (Subject Alternative Names) SSL, this certificate cover similar domains. It covers a full suite of websites. So they give flexibility for covering websites that might just go away or do not exist. A domain name registrar and its certificate of authority limit the of websites comprised under this SSL.
Organization SSL Certificate
The certificate tends to authenticate the identity of a company, and information like its primary address. It is similar to the first type of certificate mentioned in this post and tends to provide security to payment or e-commerce components of the site that uses it.
Wildcard SSL
This one offers comprehensive coverage against privacy and security threats to all subdomains on one hostname or root domain. This scenario would actually be pretty useful for a website having heavy transactional requirements.
Extended SSL Certificate
This is the most secured one among all types of certificate. It verifies the domain as well as double checks the legal corporation. In fact, when you open the site using this certificate in most modern browsers, you will see a green colored address bar.
Purchasing an SSL certificate is not complicated at all. A website owner can buy and set up one from the web hosting provider or domain registrar that they are using.
