I am using jboss as the server and my java program as the client, I have modified the server.xml file in jboss to send certificate from server to the client. this happens automatically, when the requesting client has the same domain as the domain in the server keystore.
But I want the jboss server to validate the client certificate also. How can I send the client certificate to jboss and receive it in jboss?
You are trying to achieve a two way ssl so lookup "jboss two way ssl".
The steps would be similar to setting up ssl on the server ; the only difference would be that you would need to import the client cert into the server truststore (assuming the client cert is self-signed).

Supposing I have a nginx server with mtls enabled. The nginx instance works ok for the client certificates already configured.
Is there any way to add extra client certificates (newly registered_ without restarting the server?
If not are there any servers or software solutions that resolve certificates dynamically?
A Certified Domain should be accessible only if SSL public certificate of the domain is already present in client's trust store. If not, client should prompt to import server certificate instead of getting it from tomcat server automatically(Via SSL handshake)
This will not work: the server has no knowledge which CA certificates are known to the client so the server cannot decide what to send to the client. Also, the server can only send a certificate to the client but not make the client import a new root CA - no matter if with or without prompt.
Apart from that it makes no sense: the idea of TLS/HTTPS is that the client will only connect to a server which identity can be verified. If the server can make a client import a new trusted root CA an attacker could do the same and thusman in the middle attacks would be possible.
If one instead just want to know if the client will trust a specific certificate or not one could include a resource (image, script...) served with this certificate into a known good HTML page and then check with some script in the page if the resource was loaded successfully. This check could also result in a redirect of the client, for example to some page describing the problem and linking to the correct root CA.
I am rather confused by the purpose of the trustore file in a tomcat server.
I.e use of the truststoreFile parameter when setting up a TLS enabled connector.
According to the tomcat docs:
truststoreFile
The trust store file to use to validate client certificates. The
default is the value of the javax.net.ssl.trustStore system property.
If neither this attribute nor the default system property is set, no
trust store will be configured.
To me this is telling me that for an inbound connection to my tomcat server, this is where I would store certificates that a client would present. (e.g. a users browser)
Would I really put in 3rd party CA certificates here or other 3rd party server certificates, if my tomcat server wants to make an outbound connection to a TLS enabled server (e.g. an LDAPS server)
As per my understanding the place to do this is the cacerts file.
Is my understanding of the truststore wrong?
Yes, you are right, it is quite confusing.
If you need to make an outbound connection a 3rd party, you need to add the certificates to cacerts.
There is a very popular "signing, validation, etc." service for government-owned companies here in Spain, #firma, that just changed its wildcard server certificate and we had to add it to cacerts.
iam using jboss application server.
created my own self signed certificate using keytool key and certificate management tool and configured this certificate in jboss configuration file.
for accessing different applications like in my case using web service calls between applications using https, imported my own self signed certificate to java run time environment trusted keystore i.e, cacerts.
my question is i want to access the application with ip address as well as my domain using https.
any suggestions ?
You have to make your self-signed certificate look like this:
In the certificate SubjectAltName extension, you need to add the dnsName and ipAddress extensions to it.
You could use KeyStore Explorer GUI tool to create them.
Looking to port Outbound SSL configuration from Websphere to JBoss. In my case, JBoss is the client. It wants to pass a client cert to a remote machine as part of a 2-way SSL communication.
In Websphere, you explicitly specify...
keystore / keystore password (where are the certs?)
certificate alias (which client cert to apply?)
matching outbound url pattern (when do i apply the client cert?)
You may have many of these configurations. Between these 3 pieces of info, the container can selectively choose when/which client certificate to include when making outbound SSL calls.
What is the JBoss way of doing the same thing as I described above ?
Can this be done by simply configuring your JRE ?
Are there parts of this that cannot be done in JBoss and/or java?
Thanks,
Wade.
