OCSP with openSSL

Усманов Азат Анварович
Hi everyone! I have a web app running on tomcat and java 7 using apr for TLS related issues. I m still unable to have OCSP verification working with tomcat. I'm  NOT  talking about the client- certificate based auth here,  just the opposite. I want tomcat to present it's OCSP  status to the client(browser) when it connects to the server.  Since the options on OCSP  section tomcat docs talk about client-auth I figured I don't need to add anything on my HTTPS connector to get OCSP working.  So here is my  https connector
   <Connector  allowTrace="false" server=" " port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
      maxThreads="350" SSLEnabled="true"   enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" compression="force">
 <UpgradeProtocol  className="org.apache.coyote.http2.Http2Protocol" compression="force" />
        <SSLHostConfig sessionCacheSize="50"  honorCipherOrder= "true" protocols="TLSv1.3+TLSv1.2" ciphers="TLS_AES_256_GCM_SHA384,TLS_AES_128_GCM_SHA256ECDHE-ECDSA-AES256-GCM-SHA384,ECDHE-RSA-AES256-GCM-SHA384,ECDHE-ECDSA-AES128-GCM-SHA256,ECDHE-RSA-AES128-GCM-SHA256,ECDHE-ECDSA-AES256-SHA384,ECDHE-ECDSA-AES128-SHA256">
            <Certificate certificateKeyFile="/home/idis/server.key"
                         certificateFile="/home/idis/STAR_ieml_ru.crt"
                         certificateChainFile="/home/idis/authorities.crt"
                         type="RSA"/>
</SSLHostConfig>
    </Connector>
our ocsp certificate has ocsp responder address  http://ocsp.comodoca.com
 I thought that my issues  were  caused by the fact the server in question  sits behind a proxy but I just tested ocsp stapling  manually via OpenSSL ocsp utility and it working properly  when invoked through the command line
 openssl ocsp  -no_nonce  -issuer issuer.crt -cert /home/idis/STAR_ieml_ru.crt    -url  http://ocsp.comodoca.com/ -text

 I have tried running tcpdump on the server but don't' see any Comodo related IP addresses in the output when I access the server in question in the browser.
At this point I don't know what else to do, If it was java I would just put some System.out.println statements in OCSP SSL related source code and recompile the tomcat source, but since in my case tomcat uses OpenSSL and tomcat native I'm not sure how/where to do that. the only places I found in the TC-native source that mentions OCSP  is sslutils.c  source file. I'm not sure when/ if it is actually gets called in my case. Maybe be someone with more c experience c++ would help me with that.  I really want to get to the bottom of this. Any help is appreciated
 my tomcat version  is 8.5.39
 APR based Apache Tomcat Native library [1.2.21] using APR version [1.6.5].
Openssl version is [OpenSSL 1.1.1a  20 Nov 2018
OS: Linux RHEL 6.6

How did you build the Tomcat Native library? Was OCSP enabled?

Mark,  I installed it  just   by  downloading  tcnative src  tar.gz file from tomcat  website
and issued  ./configure --with-apr=/usr/local/apr --with-java-home=/usr/java/jdk1.7.0_79 -with-ssl=/usr/local/openssl && make && make install && make clean
I'm not sure  how to specify any ocsp related configure options  when building tomcat native    from source

What is your OpenSSL version and capabilities?

$ openssl version

$ openssl -help

$ openssl ocsp -help

Chris,
Yes the version is the same in
/usr/local/openssl/bin/openssl as well.
It is the same version Tomcat uses,I get this info in the logs

23-May-2019 12:55:42.145 INFO [main] org.apache.catalina.core.AprLife

Great. Is this also the same version in /usr/local/openssl/bin/openssl?

Excellent.

When you launch Tomcat, are you getting a message about the version of
OpenSSL in use, and does it agree with above?

AFAIK, OCSP is enabled by default in libtcnative. There were some posts
a few months/years ago about someone trying to get it to work, and
having to edit the JVM's security.properties file and all kinds of weird
stuff. I must admit it didn't make any sense to me at the time. I'm
sorry, but I don't personally have any experience with dealing with
OCSP, but hopefully this additio0nal information will give someone else
some good info.

RE: OCSP with openSSL

Усманов Азат Анварович
Just a quick follow up , trying to get some answers, I added  include <stdio.h> to sslutils.c (which has alll the ocsp functions )   to print some info.I  added printf calls to every function defined in this file.  Interestingly enough  when I issue  the  openssl s_client -connect debug.ieml.ru:8443  -tls1_2 -status -proxy 192.168.1.6:3131
both tls1_2 and tls 1_3  versions and when I access  the server from another machine via browser none of printf  calls are displayed,  however, when I issue ssllabs server test (which is also supposedly capable of detecting ocsp)   some of them start to appear.  sadly none of them are ocsp related. I did put basic  ifdef  test for HAVE_OCSP_STAPLING, surprisingly  it  shows that ocsp support is indeed enabled . So here are  both   the modified  sslutils.c file and tomcat log snippet (not sure if attachments are allowed on  the list  so posting it  here )
Not sure where to go from here

Chris,
Yes the version is the same in
/usr/local/openssl/bin/openssl as well.
It is the same version Tomcat uses,I get this info in the logs

Great. Is this also the same version in /usr/local/openssl/bin/openssl?

Excellent.

When you launch Tomcat, are you getting a message about the version of
OpenSSL in use, and does it agree with above?

AFAIK, OCSP is enabled by default in libtcnative. There were some posts
a few months/years ago about someone trying to get it to work, and
having to edit the JVM's security.properties file and all kinds of weird
stuff. I must admit it didn't make any sense to me at the time. I'm
sorry, but I don't personally have any experience with dealing with
OCSP, but hopefully this additio0nal information will give someone else
some good info.

Re: OCSP with openSSL

markt
Coming back to this as it has been on my TODO list for a while.

Having re-read the thread I think it would be helpful to first clarify
exactly what behaviour you are expecting and not seeing.

The issue relates to OCSP checks when Tomcat is presenting it's server
certificate to the client.

You are expecting Tomcat to use OCSP stapling to provide the OCSP
information to the client so that the client does not have to request it
itself.

Tomcat is not providing the OCSP information. It appears that OCSP
stapling is not working.

Is the above a fair summary? If not, please provide corrections.

Thanks,

Mark

having been in contact with Усманов, I can confirm your summary.

May I add my question from February with additional info to this thread:

Thanks.

Progress can be tracked here:
https://bz.apache.org/bugzilla/show_bug.cgi?id=56148

At the moment, the pure JSSE solutions (NIO+JSSE, NIO2+JSSE) support
OCSP stapling with appropriate configuration.

The OpenSSL ones (APR/native, NIO+OpenSSL, NIO2+OpenSSL) do not.

It might be simply a configuration issue with OpenSSL. It might need
code changes in APR/Native. I'm currently looking in to that.

I was testing Tomcat 9.0.x (latest source from Git) but with the
knowledge that we haven't made *any* changes to Tomcat to support OCSP
stapling and that 9.0.x and 8.5.x have very similar TLS code.

I have just tested with 8.5.42. Both NIO+JSSE and NIO2+JSSE support OCSP
stapling. My Connector configuration is:

    <Connector protocol="org.apache.coyote.http11.Http11Nio2Protocol"
               port="8443"
               proxyPort="443"
               maxThreads="150"
               useAsyncIO="true"
               SSLEnabled="true">
        <UpgradeProtocol
                 className="org.apache.coyote.http2.Http2Protocol"
                 useSendfile="false"
                 maxConcurrentStreamExecution="50" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="/.../privkey.pem"
                         certificateFile="/.../cert.pem"
                         certificateChainFile="/.../chain.pem"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

Thanks.

Progress can be tracked here:
https://bz.apache.org/bugzilla/show_bug.cgi?id=56148

At the moment, the pure JSSE solutions (NIO+JSSE, NIO2+JSSE) support
OCSP stapling with appropriate configuration.


Do you mean on trunk or really only configuration?

I just tried it on 8.5.42 and it will not send the message on my
letsencrypt cert.

If it should work out of the box, do you mind to share the "appropriate"
config here.

I was testing Tomcat 9.0.x (latest source from Git) but with the
knowledge that we haven't made *any* changes to Tomcat to support OCSP
stapling and that 9.0.x and 8.5.x have very similar TLS code.

I have just tested with 8.5.42. Both NIO+JSSE and NIO2+JSSE support OCSP
stapling. My Connector configuration is:

   <Connector protocol="org.apache.coyote.http11.Http11Nio2Protocol"
              port="8443"
              proxyPort="443"
              maxThreads="150"
              useAsyncIO="true"
              SSLEnabled="true">
       <UpgradeProtocol
                className="org.apache.coyote.http2.Http2Protocol"

                maxConcurrentStreamExecution="50" />
       <SSLHostConfig>

                        certificateChainFile="/.../chain.pem"

I’m lost. My conf is pretty much similar.

I use a JSSE keystore - that contains the correct cert. Openssl syntax did not change anything.

Running openssl to the letsencrypt ocsp responder from the machine gives a positive result. Tcpdump shows data.

$ openssl ocsp -verify_other intermediate.pem -issuer intermediate.pem -cert xxx.crt  -text -url http://ocsp.int-x3.letsencrypt.org -header "Host=ocsp.int-x3.letsencrypt.org"

But once I connect to tomcat from outside, I don’t see any tcpdump traffic.

Any debug info I can create?
