VB.net Signing/Test Certificate


On the "Signing" tab of my project form of my VB.net Excel Add-in project I use the "Create Test Certificate" button to extend
the period that my users can use the add-in. This only creates a period a year long. Is there a way to make this longer?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you could create your own test certificate before you deploy the application and set the limit to whatever you desire

ou need to create a certificate and a private key file, and then convert those files into a .pfx file that can be used by Visual Studio. Use the following command to create the certificate and the private key file:
makecert -sv yourprivatekeyfile.pvk -n "cert name" yourcertfile.cer -b mm/dd/yyyy -e mm/dd/yyyy -r
-sv yourprivatekeyfile.pvk is the name of the file containing the private key.
-n "cert name" is the name that will appear on the certificate (and in the certificate store).
yourcertfile.cer is the name of the certificate file.
-b mm/dd/yyyy is the date when the certificate becomes valid.
-e mm/dd/yyyy is the date when the certificate expires.
-r indicates that this will be a self-signed certificate.
