AIUI, openssl ca isn't really intended for production use. I did see the RESTRICTIONS [1] and WARNINGs [2] sections in the openssl-ca documentation. I think that I can handle the problems described there but would still be interested if you have any concerns beyond those warnings and the functional limitations I am currently running into. Also what (open source) ca software do you recommend instead?
