What is a CER file?

CER is a file extension used by web servers for security and identity verification of the site in question. The security is provided by a third-party certificate authority such as Verisign, global sign, or Thawte. An SSL encryption is the file certificate file format that secures the use of a site. A digital signature is used by the certificate to bind an identity and public key together. With a certificate, the public key can be verified that they belong to an individual.
To open a CER file, you must have suitable software like an internet security certificate file. With the proper software, you will easily open your CER file. You will get an alert from your windows, mac, iPhone, or android on how you want to open the file. To successfully install an SSL on your server, it would help to determine which type your device or server requires. You can view a CER file by clicking on the lock icon at the edge of the browser window.
