Create Test Certificate Dialog Box
The Create Test Certificate dialog box creates a test certificate to be used for signing your ClickOnce application and deployment manifests. Provide this dialog box with a password for the new strong-name key file.
To access this dialog box, select a project node in Solution Explorer, then on the Project menu, click Properties. When the Project Designer appears, click the Signing tab. On the Signing page, click the Create Test Certificate button.
Enter password for new file <filename>
Enter a password for the new strong-name key file for the test certificate. The file is named projectname_TemporaryKey.pfx. If you click OK without typing a password, the .pfx file will not be password encrypted.
Confirm your password
Re-enter the password.
