Dear Gervase,

Yes, the certificate issuance process is performed by each of these five 
components, except, TSA is used for code issuance and PDF issuance, not related 
with SSL certificates issuance.

Thanks,
Xiaosheng Tan

    It might be useful if you were to explain what function in the

    Presumably the fact that this code is shared with WoSign explains why
    the StartCom serial numbers changed to be "WoSign-style" in December 2015.

    Is this server involved in SSL certificate issuance at all?
