What is CER file?

CER file is an internet security file associated with websites. The main purpose of such files is to provide the user with authentication and identification of the website itself along with the verification of the security of the website. These CER files are created by a security certificate authority which is generally a third party.

These certificates also tell about the security level of a specific website. Any person visiting the website is given certificate and the web browser checks that certificate. In case the certificate is expired or does not exist a warning is shown to the about the possible threats.

We hope we helped you solve the problem with the CER file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the CER file (apart from the lack of the proper application installed).

First - the CER file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the CER file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the CER file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the CER file has not been completed and it cannot be opened properly).
