This means that any changes introduced by hackers after launching are also identified. The protected application checks itself in the active RAM, and not simply the files stored on the hard drive. With AxProtector, the application trusts itself alone, but that is not the only step that goes beyond the standard protections built into Windows. If its signature does not match the application in the RAM, the application will close and notify the user. Trust no one, but yourself – that is the thinking behind this approach, which has the protected application check itself upon launching. The public key is also hidden within the application. Windows - AxProtectorĪxProtector encrypts the entire executable file (.exe) and appends a fingerprint with a dedicated signature. Little reason for the makers or users of pirated software to stop their wrongdoings. However, the users are only giving a simple warning message, and they can even opt out of these messages. Windows uses a built-in code signing mechanism (Authenticode) to notify users when they are using software from an unknown source, that is, software that is not signed, whose certificate cannot be traced back to a trusted root certificate, or whose signature is incorrect. This is where AxProtector and ExProtector enter the fray. It is not, however, enough to give the software developers themselves a means of avoiding piracy or tampering. This common mechanism was originally developed to protect end users from the all too frequent threat of viruses. This allows the end user to verify which developer made the software he or she is using and whether it has been tampered with. A certificate is produced by a trusted certification body and links the public key with the identity of the software developer.
