Signing InDesign extensions

Hi,

We are signing our InDesign extensions using the ZXPSignCmd-64bit command

https://github.com/Adobe-CEP/CEP-Resources/blob/master/ZXPSignCMD/SigningTechNote_CC.pdf

 

We have recently started using Digicert certificate and it appears the new signing requirements are as per the link EV Authenticode Signing using SignTool (digicert.com)

 

I would like to know if there are any update to the instructions for signing InDesign extensions to align with the updated guidance from DigiCert

 

Thanks

Asaxena,

 

Did you try ErinF's suggestion of using a self-signed cert? Did it work?

 

TIA

Yes. It works and extension installs and works fine for us

Letting you know that the new build of the ZXPSignCmd seems like it can handle certificates again!

Hello,

 

Is the trouble here that the ZXPSignCMmd no longer supports DigiCert certificates? Just checking, as I know there was change in requirements a year or two ago...

 

The only workaround I have at the moment is to self-sign your ZXP packages. Self-signed ZXPs are allowed both in our Marketplace and are installable by InDesign.
