What is an SSL Certificate?
An SSL (Secure Sockets Layer) certificate is a digital certificate that encrypts online communication between a user’s web browser and a web server. SSL certificates ensure that data transmitted between the two endpoints is secure and cannot be intercepted by third parties. When a website has an SSL certificate installed, the website’s URL begins with “https” instead of “http,” and a padlock icon appears in the browser’s address bar.
SSL certificates work by using a public key and a private key to encrypt data. For instance, when a user visits a website with an SSL certificate, their web browser sends a request to the web server. The web server responds by sending the SSL certificate, which includes the web server’s public key.
The user’s web browser then generates a unique session key and encrypts it using the web server’s public key. The encrypted session key is sent to the web server, which decrypts it using its private key. Afterward, all data exchanged between the user’s web browser and the web server is encrypted using the session key.
Types of SSL Certificates
- Domain Validated certificates are the most basic level of validation and SSL certificate type. They verify that the website’s domain name belongs to the person or organization applying for the certificate.
- Organization Validated certificates provide a higher level of assurance. In addition to verifying the domain name, the certificate authority (CA) verifies that the organization is legitimate and registered.
- Extended Validation certificates provide the highest level of assurance. Here, the CA verifies the domain name and organization and that the organization is legally registered and has the right to use the domain name.
Benefits of Using SSL Certificates
- Protection against data breaches and cyber attacks: SSL certificates encrypt data transmitted between a user’s web browser and a web server, making it impossible for third parties to intercept and steal sensitive personal data or contact information such as passwords and credit card numbers.
- Improved search engine rankings: Google and other search engines give higher rankings to websites with SSL certificates, which can lead to increased visibility and traffic.
- Compliance with data protection regulations: Many data protection regulations, such as the General Data Protection Regulation (GDPR) in Europe, require websites to use SSL certificates when collecting and transmitting sensitive information.
How to Obtain an SSL Certificate
Many web hosting providers offer SSL certificates as part of their hosting packages. This is often the easiest and most affordable option for small to medium-sized websites.
For larger websites or those with specific security requirements, third-party CAs may be a better option. Third-party CAs offer a wider range of SSL certificate options, including EV certificates, and may offer additional security features, such as vulnerability scanning and malware removal.
To install an SSL certificate on your website, you must generate a Certificate Signing Request (CSR) and provide it to the CA. The CA will then issue the SSL certificate to install on your web server. The installation process will vary depending on your web server and hosting environment, but most CAs provide detailed instructions for installing SSL certificates.
It is worth noting that SSL certificates are not a one-time purchase. SSL certificates have a limited validity period, usually between one and three years, after which you must renew. Further, SSL certificates must be kept up-to-date with the latest security protocols to ensure maximum protection against cyber attacks.
