Who needs a software publisher certificate?

When users buy software in an official physical store the source of this software is obvious. But it is not that easy to trust if they download your software file from the Internet, taking into account how easy it is for fraudsters to insert a malicious piece of code into your original software. Code Signing certificate ensures the integrity of the code and verifies the owner, and in this way it informs your customers that they can trust the software they are to install.

For example, when installing a program on Windows a user must allow the program to make changes to his computer. If the software is not signed with a Code Signing certificate, the user receives a warning that the publisher is unknown. On the contrary, if the program code has been signed using a Code Signing Certificate, the installation message will be colored in blue and no warnings will be shown.

In the first case the user does not know who created the program and whether he should trust it. That is why he can cancel the installation process and find another developer’s product. In the second case the publisher certificate guarantees that exactly this publisher has issued the software in question and no one has altered the code during its transmission to the user.
