What is KEY file?

Files with the KEY extension are popular and used by various types of key files software, utilised in the process of registering a legal copy of a given program.

Moreover, KEY files are used by sewers utilising the SSL protocol (Secure Socket Layer), to store and export digital keys.

Additional information

Such files are stored as strings of encoded keys. The KEY files used for purpose of authorising a purchase of a software, can be stored in two ways – as a plain text file, or more often – as an encrypted string of keys. KEY files have no standardised structure, therefore, they are not supported by any specific program. Every application can generate its own file format with registration key, and such file will operate properly only with an indicated application.

Other purposes

Files with the KEY extension are used also to store the Apple Keystone data (a program designed for creating multimedia presentations on Mac OS X platform). Such files contain all the data of a presentation, just like in case of its Windows equivalent – the PPTX file. This may include images, ClipArts, texts, shapes, diagrams, audio or video data.

We hope we helped you solve the problem with the KEY 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 KEY file (apart from the lack of the proper application installed).

First - the KEY 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 KEY 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 KEY 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 KEY file has not been completed and it cannot be opened properly).
