RapidSSL Wildcard is an SSL certificate designed to secure an unlimited number of subdomains under one root domain using a single certificate. It is a Domain Validation (DV) certificate that provides fast and automatic domain verification without the need to provide additional company documentation. The validation process is usually completed in a matter of minutes, making RapidSSL Wildcard an ideal solution for companies that need to quickly implement SSL protection on multiple subdomains. RapidSSL Wildcard supports data encryption using a 256-bit key, which is the modern security standard for data transmission over the network. The certificate is signed with a 2048-bit RSA key, which guarantees an appropriate level of protection against potential cryptographic threats. Additionally, this certificate supports encryption using ECC (Elliptic Curve Cryptography) keys, which allows for higher efficiency and shorter keys while maintaining a high level of security.

RapidSSL Wildcard is widely compatible with browsers and mobile devices, ensuring that over 99% of users will not encounter any issues with the certificate recognition. It works on both SSL-enabled web servers and mobile platforms. With the ability to install the certificate on an unlimited number of servers, this solution provides great flexibility in managing high-availability environments.

The Wildcard certificate protects all subdomains at one level, meaning that addresses such as mail.example.com, support.example.com, and blog.example.com are protected without the need for separate certificates. However, subdomains at deeper levels, such as mail.shop.example.com, will not be protected within the same certificate. RapidSSL Wildcard protects both www and non-www domains, which increases its flexibility in various application scenarios. The certificate is covered by a $10 000 guarantee, providing additional financial protection in the event of any certificate malfunctions. In addition to the protection itself, installing a certificate displays a padlock icon in the browser address bar, which increases the trust of site visitors.

RapidSSL Wildcard does not offer a dynamic security seal, but it does allow you to place a static seal on your page, which signals to users that your site is protected by an SSL certificate. This seal is not interactive, but it still increases visibility and trust in your site’s security. Technical support for RapidSSL users includes online documentation, knowledge bases, and the ability to contact technical support for questions about certificate installation or configuration.

RapidSSL Wildcard certificate security seal, like other RapidSSL certificates, is a static graphic that can be placed on a website to inform visitors that the site is protected by an SSL certificate. This seal is not dynamic, meaning that it does not contain an interactive link to certificate information, nor does it update its data automatically. The static RapidSSL Wildcard seal can be easily embedded into a page by placing the appropriate HTML code. It is usually placed in visible places, such as the footer of the page or payment pages, to emphasize that both the main domain and all of its subdomains are secured. Although the seal is static, its presence can increase user confidence in the site by indicating that advanced data protection mechanisms are in place.

RapidSSL Wildcard validation process includes two main methods: validation via email or DNS record. The process starts with placing an order for a certificate and providing the root domain. RapidSSL then sends an email to the addresses associated with the domain, such as admin@domain.com, administrator@domain.com, webmaster@domain.com or to the contact addresses listed in WHOIS. Alternatively, instead of email validation, you can choose DNS validation. In this case, the user must add a special TXT record to the DNS zone of their domain. This record is a unique identifier that confirms the ownership of the domain. Once the DNS record is correctly added or confirmed via email, RapidSSL processes the application and generates a certificate. This certificate protects all subdomains within a given root domain, and the entire validation process usually takes from a few minutes to a few hours.

Important: Wildcard SSL certificates cannot be verified via a file method.

The wildcard feature in the RapidSSL Wildcard certificate allows you to secure an unlimited number of subdomains within a single root domain using a single SSL certificate. With this solution, instead of generating separate certificates for each subdomain (e.g. www.example.com, shop.example.com, mail.example.com), you can protect all subdomains at once using a single wildcard certificate issued for the *.example.com format. The asterisk (*) in the domain name means that the certificate covers each subdomain at a given level, which makes domain security management much more efficient and simpler. The wildcard feature is especially beneficial for companies that have dynamic environments with many subdomains, because each new subdomain is automatically protected without the need to make changes to the certificate or purchase additional licenses. It is worth noting that wildcard certificates only protect subdomains at a single level. This means that a certificate issued for *.example.com will cover subdomains such as blog.example.com or support.example.com, but will not secure subdomains at deeper levels such as mail.shop.example.com.

RapidSSL certificates, including RapidSSL Wildcard, are highly compatible with web browsers and mobile devices. They are recognized by over 99% of browsers, which includes popular desktop browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, as well as mobile browsers on Android and iOS. The high compatibility of RapidSSL certificates means that users visiting sites secured with this certificate will not encounter any issues with warnings about unsafe connections, which translates into a smooth and secure browsing experience across devices. Additionally, RapidSSL certificates are regularly updated to meet the increasing security and compliance requirements, ensuring their long-term compatibility with new versions of browsers and mobile devices.
