Sorry, accidentally hit return and submitted too soon. To continue... In accordance with my comments in bug 167572, please add the following certificates for Unizeto Certum CA (all trust bits on): Certum Root CA: http://www.certum.pl/keys/CA.crt Certum Level I CA: http://www.certum.pl/keys/level1.crt Certum Level II CA: http://www.certum.pl/keys/level2.crt Certum Level III CA: http://www.certum.pl/keys/level3.crt Certum Level IV CA: http://www.certum.pl/keys/level4.crt Certum Validation Service: http://www.certum.pl/keys/vs.crt (There's also an NSS patch attached to bug 167572, but it doesn't include the certificate for the Certum Validation Service.
Feank, how many of these certs are root certs? It has not been our practice to include intermediate CA certs for most CAs. I think we should NOT include intermediate CA certs unless there is a good reason to do so.
(In reply to comment #2) > Feank, how many of these certs are root certs? I think that the cert marked Certum Root CA is the only true root certificate, but I'd have to double-check that. If everything will work correctly with just that cert included then go ahead and just include that one. I'll let the folks from Certum comment on this too. (I'm adding them to the cc list for the bug.)
The Certum folks are glad to see that including process goes forward. However, it's a common practice not to add the subordinate CA to a Web server. Thus, we offen got the following situation: a browser (e.g Microsoft IE with only Certum CA) is going to establish a secure connection to a server, which has only one certificate (server ID but not subordinate root CA). In that case, the whole process gonna finish with "Unable to verify the identity of .... as a trusted site". We'd like to avoid similar situations in the futre. On the other hand, you can't validate (by means of OCSP) our IDs without Certum VA, I'm sure. So, we appreciate that you are willing to add our CA but please, don't pass over subordinate CA's or at least consider it.
Hi, IMO there is no need for intermediate CA certs in Mozillas cert store. SSL/TLS server (including OCSP responder) should be able to send a complete or almost complete (except the root cert) certificate chain to the client. SSL/TLS clients should be able to resemble the trustpath and verify it from a remotely supplied chain together with the local root certs and any optionally user installed certs. If a server, a client or an application that want's to be PKIX conform can't do this, I consider them to be broken in terms of PKIX/X.509 PKI. Usually Mozilla is working fine in this respect (can't say a thing about Mozillas OCSP implementation) and admins of IISs need to configure their IIS to deliver the cert chain, which is possible but not as easy to configure as it is with Apache webservers. Importing a PKCS12 file into the right Windows certificate store using the MMC with the certificate snapin does the job. With IISs out of the box simple standard certificate/request generation procedure wizard their admins will end up with no chain being delivered. That is tough. Ask MS to get their IIS cert wizard smarter! Or use proper software. An example for a kind of broken server is postfix's STARTTLS patch which can't handle verification of client certificates down to a root cert across intermediate CA certs. Cheers Reimer
(In reply to comment #5) Hi, That's true each server shall be able to send a full certificate chain and each client shall be able to handle a server response. But in fact it's not so easy. Mozilla can't handle a OCSP response with VA certificate in it. ISS imports hardly subordinate CAs into the keystore. Ther's another problem with the IIS - it requires not only manual inclusion of the intermediate certs in the proper store, but also requires the user to wait unsepcified time before the IIS notices inclusion. One of our clients had to wait for several hours before IIS decided to build complete chain (without any further modification of the stores). It looks like a "propagation" bug of the changes to cert stores content. Therefore we would like to secure our clients against such behaviour - and add not only root CA to the browser keystore, but subordinate certs as well. We also assume, that intermediate certificates presence both on the server and client side would render us fewer problems (with not-so-briliant administrators, for example). regards, /Wojtek
Putting on NSS 3.10 radar screen
Created attachment 153451 [details] [diff] [review] patch - Add Certum root CA to builtins This adds the cert with a nickname of "Certum Root CA". Frank, I think requests for new root CAs like this need to specify two additional things: a) the trust flags. What types of certs is this CA trusted to issue? choices include: SSL S/MIME Object Signing b) what should the nickname of the root CA cert be? Please let me know if "Certum Root CA" is not desirable. I used it because it appears in the request (original comment in this bug). NB: I will be on vacation the week of July 18, so I will not reply until then.
Comment on attachment 153451 [details] [diff] [review] patch - Add Certum root CA to builtins Julien, please review, then send to wan-Teh for super-review, thanks.
I have made a nssckbi.dll with Certum's root CA added to it. I would like someone from Certum to test it for me, and tell me that they are satisfied that it works OK for them. If you are that certum person, Please email me at the email address given for me in this bug.
This has been checked in on the trunk for NSS 3.10. So, I am marking this bug fixed. We may also choose to port this enhancement back to NSS 3.9.x.
Checked in on the 3.9 branch. Checking in builtins/certdata.c; new revision: 188.8.131.52; previous 1.27 Checking in builtins/certdata.txt; new revision: 184.108.40.206; previous 1.28 Checking in builtins/nssckbi.h; new revision: 220.127.116.11; previous 18.104.22.168
Verified with Firefox 1.0.2 that "Certum CA" is in the "Builtin Object Token" with the following trust settings: This certificate can identify web sites. This certificate can identify mail users. This certificate can identify software makers. Its nickname is "Certum Root CA".
