AXX file is associated with AxCrypt encryption software. This software application allows the user to secure the data using 128bit encryption.
The encrypted file is then stored with AXX file format. A security key is required to decrypt AXX file and there is no backdoor in AXX file format making it secure. The key wrapping of the key file is done with NIST specifications. AES key wrap is used as the main structure of key file. The encryption done in the AXX file is through 128bit Cipher Block Chaining mode which has a random IV for secure data protection measure.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .AXX file, there may be several reasons that cause problems with opening and operation of the data format:
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 .AXX file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .AXX file, so download the update and check again.
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:
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.
There may be several reasons why you cannot open the file with .AXX extension. Directly on this website you can find a solution of the most common problem with the .AXX file – that you do not have on your computer the appropriate program to open the file.
