I stuck with problem how to authorize java client application that consume rest api and need to autorize by ceritication issued by internal CA. So I have CA certificate, then Client certificate and client private key generate by OpenSSL. I'm looking for guide/ example how to tell OkHttpClient to sign request with Client certificate to bypass Apache SSL autorization. All is done on internal network. Can you guys help me?! I tried so much ways that I'm lost. I need good example. The stack is Retrofit with OkHTTPClient.
here is example via cURL what I need to implement in java in smart way

how to add SSL certificates to okHttp mutual TLS connection?
In my case was mistake in private key format. I got pkcs1 and it must by pkcs8.

I've generated classes from wsdl with wsimport, wsdl location: https://somehost/wsdl. There was no problem with generation.
But when I tried to send soap request, I've received exception:
com.sun.xml.internal.ws.client.ClientTransportException: The server sent HTTP status code 403: Client certificate required
I find out, surfing the internet, that I have to add certificate in my keystore. I've done it, but this doesn't help.
And I have no idea what to do or even what to google.
Can anybody help me?(
It sounds like a mutual authentication problem.
The server is requiring that your client use a known digital certificate to sign your messages and send that information within the request. It is like a user/password mechanism, but you and the server agree to use a known key-pair for identification.
This situation usually means that the web service server administrator will generate a key-pair and send the private part of the certificate to you.
But you can send the public certificate for him as well if you created it yourself. The server must have access to the public certificate, and it maybe you will have to publish it to a Certification Authority. In some cases it has to be a commercial certificate (you will have to buy it).
You will then use the private key to digitally sign your messages.
I've found some links that may help:
Authentication Mechanisms
Java client for the X.509 secured web-service
Java HTTPS client certificate authentication
If you already did those steps, then something is wrong with your implementation or the certificate/keys provided are invalid.
I recommend you to use a mock server to make sure you are implementing the client authentication properly before you try to connect to the real service. Making it to work locally will set the knowledge you need to call the real functions. You can also ask the web service administrator to send you debug information.
Hi i am new to security domain. So please let me know if i am missing something very obvious.
I am trying to create an application that runs on https and requires a SSL certificate.
i followed the this blog to create a ssl certificate and add it to the java security cacerts.
Now i want to create a https post request to this application. The request fails every time. What i found till now is
The certificate is not verified, thats why it is not authorizing the rest call to proceed.
When i open the application in browser, it asks me to confirm the certificate, once i accept it, all rest calls start working.
Can any one tell me what can i do to avoid this(confirming the certificate.)
1. Can i bypass the ssl certificate check ?
2. Can i add certificate to every rest call.
3. Anything else that i should try.
4. I saw looking at this grails plugin, how do i create a .jks file ?
Ay help will be appriciated.
You can't bypass the certificate check on the clients' side. A very important point of having a certificate at all is for it to be signed by a trusted authority. If you have signed it yourself, you can still have an encrypted connection, but the clients can't know you're verified by a trusted third party.
You can configure the application or web server to use the keystore that your certificate is in in order to attach it to every https request. Look up tomcat ssl configuration.
I would advise that you read up a bit more on https and certificates, it's important to understand some details.
It's preferable that you delegate the ssl management to the application server instead of doing that in your rest calls yourself. See 2. Also, a .jks is just a keystore file. You already have one from the tutorial you've followed.
I have been googling a lot for this problem. There are many relevant answers, but I simply didn't find one that gave a complete view IMHO. So, here I am.
The statement of problem is as follows. Given the API information of an HTTPS service, including URL and any required HTTP headers and body format, how do you use a Jersey client to access the service? Note that the statement doesn't assume the client side has any other information from the target service beforehand.
As we know, when a web browser tries to access an HTTPS site, behind the scene, the browser will first get a certificate and a public key from the site. Then, if the browser trusts the certificate, it will use the public key to encrypt the actual request and send it. I have found many examples that explain how to use Jersey client for HTTPS given a truststore that incorporates the certificate and the public key. However, what if the truststore is not available yet? Can we use Jersey client, programmatically, to get the site certificate and public key, and use them to send the actual request, as a web browser does?
Thank you very much.
I'm interested if Google App Engine provides a way to use a X.509 Certificate to create a HTTPS connection (the server where I have to connect provides the public certificate - to encrypt data that I send and the private key to decrypt the data received from that server).
According to this post https://groups.google.com/forum/?fromgroups#!topic/google-appengine-python/C9RSDGeIraE it's not possible but 3 years passed since this answer was posted.
SSL client certificates are not currently supported. The feature request is here.
AppEngine has the ability to work with SSL certificate on your custom domain, that means the you can assign a certificate to a domain that is running on the AppEngine.
You cannot AFAIK make a request and provide a custom certificate per request.
Documentation on AppEngine SSL.
I have a Java CXF client that connects to a SSL secured Web Service with mutual authentication.
I have my keystore and my truststore properly configured on the client-side and it works fine.
I am concerned here by the fact that my keystore contains only one client certificate and on the CXF configuration it is not possible to say "ok for this SSL communication you'll use this certificate".
As I only have one certificate it's not difficult to choose the good one for CXF durign SSL handshake.
But this client will be deployed in a environment where it will be used with multiple possible client having their own certificate and each of them will be signed by the same certification authority. When the server will ask for a client certificate that is signed by a specific authority, there will be no way to distinguish one certificate from another.
How can I tell CXF (or Java) to use the proper certificate in this context?
Do I need to build as many SSL context as client certificates? (ie. having N keystore each of them containing only one certificate).
Or is there a way (in CXF conf or in Java) to say "use this certificate in this context"?
Thanks in advance for your help.
All the certificates must refer to the same client, otherwise the CAs are derelect in their duty. So they should all have for example the same subjectX500Principal. So why do you need a specific certificate? All of them identify the same client, so from an authentication point of view they are all equivalent.
It's starting to sound as though you want to use a particular certificate for authorization purposes, not just to establish identity via authentication. If so it is the wrong approach, a misuse of PKI. Authorization is an application-controlled step once you have an authenticated identity: get the identity of of the peer certificate and look up your authorization database to see if that identity is allowed to access this part of the application. Don't try to use a cacerts file as an authorization database, that's not what it's for.
I don't know if this is an option for you but I've done dynamic alias selection using WSIT before (i.e. one keystore, many private key entries). See this article for more detail. (Let me know if that article isn't enough - I can post more detail if you need)
