How to set 'Publisher' in a .NET ClickOnce application

Question

I'm publishing a .NET ClickOnce application and when the user installs it the Publisher is set as Unknown Publisher (see below).

What do I need to do to change this field? Do I need a valid SSL certificate?

Answer 1

Have a look at this article on the subject :

• A certificate generated using the MakeCert.exe utility is commonly called a "self-cert" or a "test cert". This kind of certificate works much the same way that a .snk file works in the .NET Framework: it consists solely of a public/private cryptographic key pair, and contains no verifiable information about the publisher. You can use self-certs to deploy ClickOnce applications with high trust on an intranet; however, when these applications run on a client computer, ClickOnce will identify them as coming from an "Unknown Publisher." By default, ClickOnce applications signed with self-certs and deployed over the Internet cannot utilize Trusted Application Deployment.

• By contrast, if you receive a certificate from a CA—such as a certificate vendor, or a department within your enterprise—the certificate offers more security for your users. It not only identifies the publisher of the signed software, but it verifies that identity by checking with the CA that signed it. If the CA is not the root authority, Authenticode will also "chain" back to the root authority to verify that the CA is authorized to issue certificates. For greater security, you should use a certificate issued by a CA whenever possible.

您需要由受信任的来源（例如Versign）颁发的证书，或者用户需要在安装应用程序之前将证书安装到其受信任的证书存储中。
