How to create a cerfiticate and install it on client machine automatically.

[luciano]

Hi everyone,

I want to create a application and a webservice, application connect to
web service to activate, web sevice will create a certificate to
authenticate this client, for each transaction between client anh
server, server will check cerfiticate of client connect to it. How do i
do that? Thanks for your reply.

In general: (warning... it has been years since I have done this... I may be
fuzzy).

You will need to install certificate services on your server. Then, you
will need to make sure that your client trusts the certificates issued by
your server's certificate authority. Then, you will need to set up your web
service to require client certificates. Your client will have to generate a
public key and send it to the server. The server will embed it in a
certificate, sign it, and return it to the client to become your client
cert. Your app will have to make sure to select the correct client cert
when calling the web service (there could very well be more than one client
cert on the client machine).

In specifics: I haven't tried this. I couldn't tell you the calls needed to
make it work.

This is a bit complicated. It also doesn't appear to buy you much. If you
are trying to make sure that the client has a license to use your service
before calling the service, this could potentially work. It is unclear if
this is what you are trying to do and if it is, why you would need to
automate it. Certificates are rarely if ever issued to machines. They are
issued to people. Your app concept appears to issue the cert to a machine.

What is your intent in this interaction? What specific threat scenario are
you trying to mitigate?
