SSL Certificate

128-bit SSL means that data communication between the website and the visitor is protected with a 128-bit encryption key. This encryption method prevents the transmitted information from being read by third parties, providing a basic level of secure data transfer and offering sufficient security for many standard websites.

256-bit SSL refers to data communication being protected with a 256-bit encryption key. It has a much stronger security level than 128-bit encryption and is especially preferred for e-commerce sites, payment systems and platforms processing sensitive user data.

To add an SSL certificate, you first purchase an SSL certificate and install it on the domain via the hosting panel or server. After the installation is complete, the website is configured to run over the HTTPS protocol instead of HTTP, and with the necessary redirects all site traffic is served over a secure connection.

SSL certificate prices vary depending on the certificate type, the brand provider and the validation level. While simple domain-validated (DV) SSL certificates usually start from a few hundred liras per year, organization-validated (OV) and extended-validation (EV) SSL certificates may be offered in higher price ranges.

SSL certificate migration is the process of transferring an existing SSL certificate to another hosting account or server. As long as the same domain continues to be used, the certificate can be reissued and installed on the new server, and thanks to this process it can continue to be used on a different infrastructure before it expires.

SSL certificates are divided into different types according to their validation level and purpose of use. The most common SSL types are domain-validated (DV) SSL, organization-validated (OV) SSL and extended-validation (EV) SSL certificates. There are also special certificate types used to protect multiple domains or subdomains, such as wildcard SSL, multi-domain SSL and SAN SSL.

If your website does not have an SSL certificate, a prominent "Not Secure" warning appears in the URL bar of your visitors' browsers, and since all data flow between the server and the user is transmitted unencrypted as plain text, sensitive information such as passwords, credit card details or personal data can easily be intercepted, read and stolen by cyber attackers.

Yes, an SSL certificate is absolutely necessary in today's web world; because it both increases brand trust in your site by ensuring user security, forms the basis for compliance with legal data protection standards such as KVKK/GDPR, and directly affects your site's visibility since search engines like Google use a secure HTTPS connection as a search engine optimization (SEO) ranking criterion.

To fix an SSL error you encounter on your website, you should first check whether the certificate has expired; if you are getting a mixed content error, you should use redirect plugins or database queries to update the links starting with HTTP (images, CSS or JS files) in your site's source code to HTTPS; and finally you should make sure that your server's date/time settings are correct and that the CA root certificates were fully installed during the SSL setup.

An invalid SSL certificate means that the security certificate presented by the visited website is not considered trustworthy by the web browser for various reasons; this is usually caused by the certificate's expiry date having passed, the certificate being created by an untrusted source (for example, self-signed), the domain in the address bar not matching the domain registered to the certificate, or the intermediate validation files in the certificate chain being incompletely installed on the server.
