OpenCA Labs The OpenCA PKI Research Labs, born from the former OpenCA Project, is an open organization aimed to provide a framework for PKI studying and development of related projects. As the PKIs standards, interests and projects are growing fast, it has been decided to split the original project into smaller ones to speed up and reorganize efforts. Some projects have already started and received (whenever possible) funds, while others are finding their way to the final decisional stage.
