Digital Certificate

I searched the reddit post for Digital Certificate signature and I saw that about a year ago, people said that it will be released in the future releases and 7 months ago someone said that it will be released in the next one. Now I am using PDFgear V2.1.12 (latest version) but there isn't any Digital Certificate option yet. Or maybe there is but I cannot find it.

Don't get me wrong, I am very happy with PDFgear but I would be much happier to completely put Adobe out of my computer!!
