What Is a KEY File?

You are reading this because you might have come across a file that ends with .key file and your computer does not seem to be able to open it.

Maybe you just curious to know what a . key file is, do not worry it will be explained clearly. We will also show you some recommended software you can use to open a KEY file.

They are few files that use the .key extension but contain very different information in them. They are a few two most common and very popular types. Let us call them file type 1, file type 2, and file type 3.

File Type 1

File type one is what we call a computer key file (or just a key file). It contains encryption data or licenses keys. These files might just be plain text or a random encrypted license key.

These keys are used mostly for software registration and authentication. They are used to confirm if a user got or purchase software legally. For example, if a person wants to buy a Microsoft application like Microsoft Office, after buying the user might be given a license key type in the application to prove he is a legal purchaser.

File Type 2

File type two is what we call a security key. These are file that tightly encodes its other devices. They are devices with tough authentication that enable access into another device ( or devices), online systems, or even applications.

In simple terms security keys are like smartcards, their only use is to give you access to another device or application. They are used as a single sign-on (SSO) or a Multi-factor authentication key.

They can be also used as a one-time password to any device application. An example of a security key is Google’s Titan security key.

File Type 3

Another KEY file type is a KEYNOTE Presentation. The keynote presentation was created by apple and is mostly used by students professionals or basically anybody that wants to create a presentation.

It is free software available for Mac, iPad, and iPhone and also available in the AppStore if you need to download it.

It is similar to Microsoft’s PowerPoint and Google’s google slide.

Is It Safe to Open KEY Files?

Starting with file type 3, regularly it is safe to open it, as long you created it with a virus or malware-free system. But in the case where you collected this file from some else, it will be wise to find out how that person got the file and if it has done any damage to his digital files or system.

The reason why you have to be careful is that hackers often disguise malicious files as good clean files in other to corrupt your system or hack it to gain access to your information. So generally be careful when opening files that you cant verify if they are safe or not.

Know with file types 1 and 2, it will be wise not to open them, because they contain sensitive and important data. Just trying to open then can lead to loss of data if not done properly.

As for file type 1, you should only use it, if it came from a trusted party, and should be used with the instruction given by the trusted party.

For file type 2, due to the highly sensitive nature of this, it should not be tampered with. This type can hold access to various devices and systems from small computers to a encrypted safe holding millions if not billions of dollars.

So it will very smart not to even try to open it or use it except you are the owner and know its particular use.
