It will allow me to ask for the certificate. If I return right now to my machine with that executable for being signed I can exit from PowerShell, and go to certificate management by typing certmgr. Click okay and now my Certificate Authority will issue certificates for the purpose of signing. If I return to the Certificate Authority console I can click new certificate template to issue and I can select secure signing for code signing purposes. Of course, I can click okay and I have a CQ Signing template being present. Now I can right click, select manage, go to the templates and select code signing template, duplicate it and apply my own name: CQ Signing.Īnd go to other properties to verify how I can issue a certificate based on this template if all those properties are acceptable for me. It has to be loaded from Active Directory. I will launch my Certificate Authority console and under certificate templates and by default there is no template about code signing.
I will switch to Certificate Authority over here. If you are signing file for internal usage like your own company utilities and so on, you can use CA your own Certificate Authority for this purpose. It will verify if the file was not altered. But such certificate will be next to useless because it will be only trusted by myself. It can be any certificate with the proper purpose, for example, I can run PowerShell and then issue a command New-SelfSignedCertificate with the proper KeyUsage and then CertSign and so on and so on.
To have a digital signature, first, we have to have the certificate used for signing. Step by step on how to get the certificate There is an interesting fact here: it is not written as you can spot by the icon in any of Microsoft development environments and still can be perfectly well signed, without any problem. You can see there is no digital signature over here. This utility is written for some forensic purposes and it’s not digitally signed.
I have my virtual machine up and running and on my desktop, I have my RDcache utility. We will also discuss what will happen with your signed code if your certificate expires. In this episode, we will show you everything about Code Signing: how to get a certificate (commercial certificate or your own one), how to sign a code, verify those signatures and show how do they work and what we can do about it.
