Hi All,

I have generated two SSL certificates and both the certificates are present in one Keystore. And the keystore is associated with Broker and eg.

I have shared one certificate to one application and another to another application who sends the messages to the application where the certificates are generated?

I have not tested this. Kindly let me know if having two SSL certificates in single keystore and two applications are trying to connect and is that works?

Why not? Probably faster than posting here and waiting for a reply.

By which can we take it to mean you've generated 2 public/private certificate pairs and you've add one half to the broker's keystore? And you expect you to guess what half of the pair?

No application should be generating any certificates. Clearly again you expect use to guess which certificates you're sharing.

We can't possibly tell you if this is going to work. You make no reference to the trust store and if no-one trusts the certificates it doesn't matter if you've done it right or not. You also don't make any reference to how the applications you've shared the certificates with plan to use them. Web services? WMQ messages? Just stored in a keystore in the hope that's good enough.

1 quick test will give you much more information than any reply here possibly could from what you've told us.

The Applications use the web services. The both the certificates generated are the privatekeys.

Actually the certificate which the applications are using, is got expired. even after the expiry the web services are working.

I have used the below command to generate key.

gsk7cmd -cert -create
-db keystore_name
[-pw password]
-label cert_label
-dn "distinguished_name"

Now, I have created the new certificate and provided the new certificate to the applications.

So, now As I am having both the certificates in the keystore as generated by the above command. If one of the applications not changed to the new certificate which I have provided. Does both the applications still be able to communicate?

This is the production issue and we can not test.

Then your SSL configuration is hosed. New certificates will not fix this.

And you only have a production environment? There's nowhere else on your site you can test?
