How to find SSL certificate version and URL expiration date in PHP? A lot of people want to know because PHP is very popular. Of course, SSL certificates are also fast gaining in popularity and for good reason.
The Need for Improved Security
Computers are changing the world every single day. When the World Wide Web came along, the way computers do things really took a whole new direction. Being able to have a website with information made it necessary for computer engineers and other people with the technological knowledge to put certain security measures into place. Security is everything now because when a person goes on the World Wide Web to buy something or to pay a bill, everyone wants that website to be as safe as possible.
What is the Solution?
To help come up with ways to make websites safe, web browsers implement something called an SSL protocol and certificates. Of course, you want to make sure that everything is in place. This is why you want to know how to find the SSL certificate version. In addition, you also want to know the URL expiration date. But just how can check the expiration date of the SSL, which stands for secure socket layer? Also, is there a way to check these things in PHP? Here is more information on how to find SSL certificate version and URL expiration date in PHP.
Here are the steps you need to follow to find the information you are looking for:
Step 1: It is time to do a little experiment and a test to see just how secure things are. You need to change the settings on your server involving your host file to another domain name. You can use any web address you want.
Step 2: Time to set up a host: You are going to create your own certificate for a host that you are setting up. You can just use an IP in your area.
Step 3: Now it is time for you to do a little test to see what will happen. Place a file on the URL, this will be your test.
Step 4: With your little test file in place, now you need to make a PHP script that will test the file of yours on the server you set up. Be sure you use the https://, and you can use a CURL or Zend HTTP.
Step 5: Now it is time to run the big test and see what exactly is going to happen.
Step 6: You will more than likely see an error when you run your little experiment.
What does all this mean and what exactly did all of this prove? Did you get an error or did you test full of fake stuff worked just fine? If you did not get an error then you are having a major security problem with the SSL certification. You need to do something about this before a hacker comes along and does some pretty serious damage.
