I'm trying to call open banking production endpoint but It keeps kicking me out as I believe root certificate for MTLS is not picking up from the certificate store. How does postman pick the correct certificate from the certificate store?
Following is what my sandbox request looks like and it's working just fine as the certificate is getting from the certificate store.
But for production I get;
Error: write EPROTO 1316197336:error:10000410:SSL
routines:OPENSSL_internal:SSLV3_ALERT_HANDSHAKE_FAILURE:../../third_party/boringssl/src/ssl/tls_record.cc:587:SSL
alert number 40
When you uploading a certificate to your certificate store, is there any additional setup you have to do?
In order to use client mTLS certificates in Postman you need to configure them for each particular domain through Postman settings.
So you need to open Postman Settings -> select Certificates tab -> press Add Certificated (under Client Certificates) -> Provide Host you are connecting to as well as your certificate file and private key for the certificate (or alternatively you could use a PFX file). Also remember to provide a Passphrase from your private key, in case you use one.
And for another host you would be able to use another client certificate, which is handy.

Good day,
My web application need to connect to IBM third party to get some response. Thus, IBM give me a .p12 file which contain of client certificate.
At first I import this .p12 file into my existing CellDefaultKeyStore, and it will hit certificate chain error.
com.ibm.jsse2.util.j: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by xxx is not trusted; internal cause is:
java.security.cert.CertPathValidatorException: Certificate chaining error
Then I go import this .p12 file into NodeDefaultKeyStore, and surprisingly its work. My application able to call to the third party and get reponse code 200.
I am not understand how to explain to my client on this.
As my understanding, management scope in CellDefaultKeyStore is bigger because its in cell, NodeDefaultKeyStore should consider part of cell only, suppose CellDefaultKeyStore should work.
Anyone can advise on this?
Just to shortly explain few concepts:
CellDefaultTrustStore - is store for signer certificates, for the servers that you connect to, to be trusted. It is shared by all the nodes and servers by default
NodeDefaultKeyStore - is store for private certs, so the certs that are used for client authentication. Each node by default has its own store and private cert to authenticate.
CellDefaultKeyStore - is store for private certs associated with the cell. Used by deployment manager, not nodes serving apps. It is NOT used by federated nodes.
NodeDefaultSSLSettings - this manages SSL config for the given node, you can check it. By default it is using NodeDefaultKeyStore (not CellDefaultKeyStore), and CellDefaultTrustStore
But back to your question.
If you need to connect to some service using client certificate authentication, what you should do is:
create new keystore with cert from the p12 file
create new truststore with all signer certs required to connect to that service
create new SSL Config that will point to these stores
create Dynamic outbound endpoint SSL configuration settings, pointing to your ssl config, select correct client cert, and specify connection info in the form protocol,host,port
This configuration will be picked up when you will be doing outbound ssl connection that matches info you entered.
I have created a couple of API's and now I have to test them using Fiddler or any certificate friendly tools. The requests which are not having valid certificate must be rejected by the server.
Certificate Background
Here are the two certificate's issues by CA
I have one intermediate public certificate entitled as
MyIntermediate.cer
I have a private certificate for each device which will request my API to fetch data.
I have uploaded public certificate - MyIntermediate.cer to server [Azure APIM]
Now to test the API's, I have to use some tools like Fiddler or Postman or any other tool which supports certificate upload/reading from store
I do not see any options in these tools to upload or read from windows store. Here I need help
I see settings in postman but it seems like not for CA certificates because I do not have key file.
APIM Details
Azure API manager is the service provided by Microsoft. All the request will be processed by APIM. I have uploaded MyIntermediate.cer public certificate to APIM. So, to call GetCustomer someone has to have certificate which is trusted by MyIntermediate.cer.
You need to have "private certificate for each device" along with it's password (if it was saved with one) to make an authenticated call. If you want to rely on APIM's ability to validate certificate chain then you'll indeed need to upload intermediate certificate, and possible root certificate as well if it's not one of the public ones.
I have to develop a web application that is both secured over https and uses client authentication certificates. The clients are connecting via invitation, thus it is not intended for users stumbling upon this application by googling around.
The ideal would be to get an intermediate CA certificate form a public root authority and sign both the ssl certificate and use it to issue client authentication certificates. I think that won't work, as simply put I will never qualify for such an intermediate CA (as far as I know, but maybe I am wrong with that).
Second guess: create own Root CA, an intermediate CA and use them. Because of what I wrote about the users, I can embed the necessary certificate chain in the issued certificates. This technically works.
What I would prefer is to get an ssl certificate from public authority and to use my own chain to issue authentication certificates and verify the users. According to this it is possible. But I haven't found anything about how to configure IIS for example (or Kestrel) to request client certificates issued by a specific CA, even less some standard specification where this flow is described.
Basically our iOS app needs to communicate with a server which has a self signed certificate for now. In my app, the https is failing with untrusted server certificate which is understandable. The error is like this:
Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “my host name here” which could put your confidential information at risk."
So I sent the self signed certificate via email to the iOS device and imported into the profiles and hoping that it would be used as part of root CA for https authentication. To my surprise, it is not and I am still getting the same error. I think that iOS would be default to use root CAs at keychain to validate the server certificate and from what I read, the imported certificate at profiles are at keychain as well. So I could not understand why my imported self signed certificate is not used as root CA.
At this point, I don't really want to trust this self signed certificate via the coding like this iOS authenticate HTTPS with self-signed certificate or In iOS, how to connect to a server using https with self-signed certificate on the server? since this won't work in customer case where they would install our server on their network and they could create their own self signed certificate.
Somehow I didn't really get much information around this from searching. Could anyone shed some lights here and what I need to do to debug this? Thanks very much.
Update on July 15:
More update around this. I also tried to use configuration profile to add a self signed CA to root CA at the iOS device by following Adding Trusted Root Certificate Authorities to iOS , from my testing on 6.0 iPad and iPhone, it doesn't work as well. So not sure if that only works on jail broken device or not. In the end, I end up by allowing user to import a self signed certificate into the app. The app would load such imported certificate for certificate verification similar to this In iOS, how to connect to a server using https with self-signed certificate on the server?. Hope that it would help others in this case.
looking at the first tutorial you linked to you should be able to use that or some more advanced form of that and once you have tested and have it working then all you have to do for a client to create and add their own certificate would be to override/replace the localhost.cer file in the apps folder where the file localhost.cer "or whatever name scheme you use" is located. there are many ways to do this but one could be telling the app a link where the certificate is online for download and once downloaded, then replace.
Any questions I'll try and help further but hopes this helps you in the right direction.
I'm working on Jboss 5 and WAS 7.
I was able to run my application via Mutual Authentication on Jboss following this doc,
https://community.jboss.org/wiki/SSLSetup/
Following the above doc I created server.keystore and server.truststore files that I injected into the Jboss server and everything works fine.
Now, I want to run the same application via Mutual Auth on WAS.
On WAS, the trust store and keystore are specified by navigating to
Security > SSL certificate and key management > SSL configurations > New > Key
stores and certificates
But there I don't see any type related to .keystore and .truststore.(snap below)
My question - what is the equivalent of .keystore and .truststore that can be used in WAS OR what's the way to set up a Browser based Mutual Authentication on a WAS server.
I'm using WAS 7.0.0.21.
Keystores and truststores are the same format in WebSphere. You choose the file format, but any of those formats can be used for either store.
You then point a configuration at specific files.
Security > SSL certificate and key management > Manage endpoint security configurations
Alternatively, what has been simpler for us is to use the existing default stores WebSphere already has and add our certificates to those.
Security > SSL certificate and key management > Key stores and certificates > CellDefaultKeyStore
Or CellDefaultTrustStore or NodeDefaultKeyStore, etc.
The link helped me setup SSL on WAS. I just had to add a couple of steps to enable it for Browser based Mutual Authentication.
Since, I had to do a POC hence I'm using Self Signed Certificates.
In a ideal scenario Certificates will be signed by a Certificate Authority and the Certificate of Certificate Authority will be imported to the Trust Store of a WAS Server.
Here are the steps,
Change the password for Default KeyStore and Default TrustStore in WAS
Create a Client Certificate in WAS
Create a Server Certificate in WAS
Export the Client Certificate in PKCS format, e.g. client.p12
Export the Server Certificate in PKCS format, e.g. server.p12
Import the Client Certificate to Default TrustStore
Import the Server Certificate to Default TrustStore
Enable SSL on WAS.
i. Make sure the to select server certificate for both Default server certificate alias and the Default client certificate alias.
ii. In the Quality of protection (QoP) settings, choose Client Authentication as Required.
Create a Web Container Transport Chain with a new SSL port, e.g. 9444.
Add the newly created SSL port to the virtual Host.
Restart the Server.
Import the Client Certificate created in Step 4 client.p12 to the Browser.
