File extension .CNG

File description

.CNG file is related with CryptoNG software application. This is encryption software application. For encryption purpose AES-GCM 256bit encryption algorithm is used.

This ensures security of the data and its integrity as well. The .CNG file contains the content which is encrypted in AES-GCM encryption form. This format uses authenticated encryption and therefore it contains two parts; tag and data. The data is encrypted and tag is validated the cypher text when decryption is required. The password for decryption is not saved within CNG file format unlike other encryption techniques and there is no backdoor available in this format either.

Description of the problem

If you have on your computer a .CNG file that you cannot open, you are in exactly the same situation as thousands of other people who have similar problems with this or any other unknown file.

There may be several reasons why you cannot open the file with .CNG extension. Directly on this website you can find a solution of the most common problem with the .CNG file – that you do not have on your computer the appropriate program to open the file.

Solution

From the list below, select the appropriate program, install it and double click on the icon of a file that did not want to open - the problem with the .CNG file extension should be solved. However, if this does not happen, go back to the website to learn about other possible causes of the error, which have been described at the bottom of the website.

Other possible reasons why your .CNG file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .CNG file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .CNG file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .CNG file, so download the update and check again.

2. Incorrect .CNG file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .CNG file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
