Personally identifiable information - such as full name, address, date of birth, or telephone number. Credit card transactions or bank account information. Most browsers tag HTTP sites – those without SSL certificates – as "not secure." This sends a clear signal to users that the site may not be trustworthy – incentivizing businesses who have not done so to migrate to HTTPS.Īn SSL certificate helps to secure information such as: HTTPS is the secure form of HTTP, which means that HTTPS websites have their traffic encrypted by SSL. More relevant to businesses is the fact that an SSL certificate is required for an HTTPS web address. SSL certificates help keep online interactions private and assure users that the website is authentic and safe to share private information with. If a website is asking users to sign in, enter personal details such as their credit card numbers, or view confidential information such as health benefits or financial information, then it is essential to keep the data confidential. Websites need SSL certificates to keep user data secure, verify ownership of the website, prevent attackers from creating a fake version of the site, and convey trust to users. The public key (the private key is not revealed). The Certificate Authority's digital signature. Which person, organization, or device it was issued to. 
The domain name that the certificate was issued for. Details typically included within SSL certificates include: To view an SSL certificate's details, you can click on the padlock symbol located within the browser bar. This signals trust and provides reassurance to those visiting the website. A padlock icon will also display in the URL address bar. Without an SSL certificate, only the letters HTTP – i.e., without the S for Secure – will appear. 
When a website is secured by an SSL certificate, the acronym HTTPS (which stands for HyperText Transfer Protocol Secure) appears in the URL. This process is sometimes referred to as an "SSL handshake." While it sounds like a lengthy process, it takes place in milliseconds.
Encrypted data is shared between the browser or server and the webserver. The web server then returns a digitally signed acknowledgment to start an SSL encrypted session. If it does, it signals this to the webserver. The browser or server checks to see whether it trusts the SSL certificate. The web server sends the browser or server a copy of its SSL certificate in response. The browser or server requests that the web server identifies itself. A browser or server attempts to connect to a website (i.e., a web server) secured with SSL. This data includes potentially sensitive information such as names, addresses, credit card numbers, or other financial details. 
It uses encryption algorithms to scramble data in transit, which prevents hackers from reading it as it is sent over the connection. SSL works by ensuring that any data transferred between users and websites, or between two systems, remains impossible to read. However, the initials SSL stuck, so the new version of the protocol is still usually called by the old name. A revamped and renamed version followed - TLS (Transport Layer Security), which is still in use today. Since its inception about 25 years ago, there have been several versions of SSL protocol, all of which at some point ran into security troubles. When you see a padlock icon next to the URL in the address bar, that means SSL protects the website you are visiting. In short: SSL keeps internet connections secure and prevents criminals from reading or modifying information transferred between two systems. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.Ĭompanies and organizations need to add SSL certificates to their websites to secure online transactions and keep customer information private and secure. An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection.
