Can a wildcard SSL be used on multiple domains?

Can a wildcard SSL be used on multiple domains?

Yes, you can use wildcard SSL on multiple domains. Wildcards can be added to the Subject Name field and a domain matching the wildcard domain will be applied.

Wildcard SSL can be used on a single site or multiple domains. The certification that you purchase enables it to be shared across websites, but the certificate can only remain valid for as long as the domain that issued it.

A wildcard SSL certificate can be configured for multiple domains. With the wildcard approach, you declare one or more CAs that are trusted for subdomains.

How many sub domains can I secure with a wildcard certificate?

Unlimited, provided that every sub domain uses the same base domain. If “books.com” is your base domain, you can use a single wildcard certificate to secure sales.books.com, www.books.com, secure.books.com, and shop.books.com.

Is SSL safe on public WiFi?

With the growing prevalence of public WiFi, it is important to take some precautions to ensure that you are safe. If you’re using public WiFi without a VPN, your DNS requests will be unencrypted, which opens you up to being tracked and exposed just like your regular web browsing habits.

Of course, SSL encrypts everything it can. But if you’re accessing these sites on public WiFi, your sensitive data will be vulnerable to capture.

SSL on public WiFi comes with risks, however, in some instances it is the only way. If for example, you are using WiFi to upload sensitive information about your firm, then you will want to ensure that all data is kept safe without exposing yourself.

What is the cost of SSL?

An SSL certificate costs, on average, $60 a year, but prices might vary greatly. To give you an idea, it can cost anything between $5 and a staggering $1,000 each year, depending on the security requirements of your website.

Does Google give free SSL?

Google does provide free SSL integration for websites that have Google Apps for Business. Yes. Google will provide free SSL once you are using Google Chrome or Chromium as your browser. You can enable this by going to the URL settings section of a website that requires an https:// prefix. A message similar to “This site requires encryption” will appear along with a checkbox: “Show warnings for unencrypted connections and show an unencrypted icon in the address bar”

What is SSL’s replacement?

The SSL replacement technology is called Transport Layer Security (TLS). An enhanced version of SSL is TLS. Similar to how SSL operates, it uses encryption to safeguard the transmission of data and information.

Has SSL ever been hacked?

Although technically possible, there is a very low chance that an SSL will be exploited.
