Sign windows application

Question

I have an SSL X.509-certificate, which is issued for me and signed by an official CA (Certification Authority) .

I know, that VS allows to sign your .NET-Assemblies with a given certificate. Will this remove the Windows The publisher of this Application could not be verified -message when someone executes my signed application?

And if this is not the case, what must I do to the remove the message mentioned above?

Answer 1

You cannot use SSL certificate to sign the code as it is intended for Server Authentication purposes only. You have to purchase a special code signing certificate that includes Code Signing (1.3.6.1.5.5.7.3.3) entry in the Enhanced Key Usages extension.
