How To Export LTPA Keys From WebSphere Application Server

In this tutorial, we will learn and figure out how to export LTPA keys from WebSphere application server. The LTPA keys are used to help single sign-on (SSO) in WebSphere Application Server (WAS) over multiple WAS domains or cells, you just have to share the LTPA keys and the password across domains.

A common set of server encryption keys will be created and exported to enable single sign-on on all servers running the application. The visitors who are accessing the website for the first time will have to log in with a user ID and password. This information will be checked against the user registry (such as LDAP). The server will use the LTPA service to create a security credential token and write the cookie back to the browser (non-persistent). When the user later visits another LTPA server in the same domain, the information in the shared cookie will be reused to establish the user's security context with LTPA. Therefore, there is no need for a second login prompt.

Steps To Export LTPA Keys:

1. Open a browser and log in to the WebSphere Application Server (WAS) console, also known as WAS console (Integrated Solutions Console).
2. First, look at the middle left of the screen and click the Security tab. After that, click on Global Security and then click on the LTPA radio button link.
3. In the cross-cell single sign-on section, you can enter the password of your choice in the password and confirm the password field.
   
   
4. Then Enter the key file name in the field and click on Export keys.
5. Click on OK.
