Hello cedric,
If the file is actually damaged to this extent, no, it can’t be fixed. The data is just not there to decrypt it.
But we have a feature called Try Broken File. You can able to decrypt the corrupted AxCrypt encrypted files by navigating the menu File | Options | enable Debug from the AxCrypt app.
Now you can able to see the Debug the menu in the AxCrypt app. From the debug menu you have to select Try Broken File.
Now you will be prompted for file selection. Select the corrupted encrypted file and then AxCrypt will try to decrypt the file. If successfully decrypted, then you are able to see the decrypted file in the location. Otherwise sorry to say, AxCrypt can’t decrypt that file.
If your recover encrypted file(s) are good condition you can decrypt the files.otherwise, If the file is actually damaged/corrupted to this extent, no, it can’t be fixed. The data is just not there to decrypt it.
If you have any queries, please feel free to contact our support via support@axcrypt.net.
