What is SSL certification?

An SSL (Secure Sockets Layer) certificate is a digital file that authenticates a website's identity and enables an encrypted link between its server and a user's browser, turning HTTP into HTTPS, indicated by a padlock icon and secure URL. It protects sensitive data like logins and credit card numbers from hackers by scrambling information during transmission, ensuring privacy and trust for online transactions and personal data submission. Essentially, it acts as a digital passport and key for secure online communication.

What is the purpose of an SSL certificate?

SSL certificates are what enable websites to use HTTPS, which is more secure than HTTP. An SSL certificate is a data file hosted in a website's origin server. SSL certificates make SSL/TLS encryption possible, and they contain the website's public key and the website's identity, along with related information.

What are the three types of SSL certificates?

There are three types of SSL Certificate available today; Extended Validation (EV SSL), Organization Validated (OV SSL) and Domain Validated (DV SSL).

Who needs an SSL certificate?

Any website asking users for information requires an SSL certificate to prevent cyber criminals from intercepting data. Confidential information isn't just credit card numbers; it could mean any personal information, including an email address or phone number.

What happens if I don't have an SSL certificate?

SSL certificates grant authentication to your websites or domains and are critical for ensuring proper encryption of internet traffic and verified server identity. Without these certificates, end users will have no way of knowing if the website they are currently browsing is what it claims to be.

SSL/TLS Explained in 7 Minutes

Why is SSL no longer used?

SSL (Secure Sockets Layer) is obsolete because its older versions (SSL 2.0, SSL 3.0) contain critical, unfixable security flaws like POODLE, allowing attackers to decrypt data, and it lacks modern cryptographic strength, leading to its replacement by the much more secure and advanced TLS (Transport Layer Security), with TLS 1.2 and 1.3 being current standards. While the term "SSL" is still colloquially used, technically, any reliance on actual SSL protocols leaves systems vulnerable to major breaches, prompting organizations and browsers to phase it out completely for TLS. 

What is SSL called now?

SSL was replaced by TLS, or Transport Layer Security, some time ago. SSL handshakes are now called TLS handshakes, although the "SSL" name is still in wide use.

What is an example of SSL?

SSL provides a secure channel between two machines or devices operating over the internet or an internal network. One common example is when SSL is used to secure communication between a web browser and a web server. This turns a website's address from HTTP to HTTPS, the 'S' standing for 'secure'.

What is better than SSL?

TLS is built with advanced features that SSL lacks. This makes it a more reliable choice for today's security needs. Older versions have been discontinued due to security risks. The latest versions of TLS are considered the most secure and efficient.

How long do SSL certificates last?

Certificate Lifetime refers to how long an SSL/TLS certificate is valid after it's issued. Right now, certificates can last up to 398 days, but with the upcoming changes, they'll expire much sooner, down to just 47 days by 2029.

Can I get an SSL certificate for free?

Start securing your websites with free SSL/TLS certificates from Let's Encrypt. In order to get a certificate for your website's domain, you have to demonstrate control over the domain. Learn about our certificate issuance process and best practices.

Should I pay for an SSL certificate?

Why do people pay for SSL certificates?

The Benefits of a Paid SSL Certificate

Stronger Encryption: Paid SSL certificates from commercial CAs often offer higher levels of encryption, providing enhanced security for your website.

What happens if an SSL certificate expires?

When an SSL certificate expires, it means that the certificate is no longer valid. This causes disruption to the secure connection between a website and its visitors and can mean that sensitive data such as login credentials, payment information, or personal details, are not secure.

What is SSL for dummies?

An SSL certificate is a file installed on a website's origin server. It's simply a data file containing the public key and the identity of the website owner, along with other information. Without an SSL certificate, a website's traffic can't be encrypted with TLS.

Who provides an SSL certificate?

DigiCert delivers certificate management and security solutions to the majority of the Global 2000.

Does anyone still use SSL?

In fact, most modern web browsers no longer support SSL at all. TLS is the up-to-date encryption protocol that is still being implemented online, even though many people still refer to it as "SSL encryption." This can be a source of confusion for someone shopping for security solutions.

What does an SSL certificate look like?

SSL certificates create a foundation of trust by establishing a secure connection. To assure visitors their connection is secure, browsers provide special visual cues that we call EV indicators—anything from a green padlock to branded URL bar. SSL certificates have a key pair: a public and a private key.

What is replacing SSL?

TLS is the direct successor to SSL, and all versions of SSL are now deprecated. However, it's common to find the term SSL describing a TLS connection. In most cases, the terms SSL and SSL/TLS both refer to the TLS protocol and TLS certificates.
