- Open the WebSphere Application Server Integrated Solutions Console and sign in.
- Go to Security -> SSL certificate and key management -> SSL configurations -> NodeDefaultSSLConfiguration (or CellDefaultSSLConfiguration or whatever SSL configuration is currently being used).
- Click Quality of Protection (QoP) under Additional Properties.
- Select the radio button next to Custom protocol list in the Protocol section.
- Select the TLSv1.3 and TLSv1.2 protocols in the box on the left and click the Add >> button to move them to the right box to enable these protocols.
- Click the OK button and then the Save link at the top of the page to save the changes to the master configuration.
- Restart the WebSphere Application Server instance to enable the use of the TLSv1.3 & TLSv1.2 protocols for all TLS connections.
-
STRQSHcd /QIBM/ProdData/WebSphere/AppServer/<V85 or V9>/<Express, Base, or ND>/binstopServer -profileName <profileName>startServer -profileName <profileName>
-
- WRKLNK '/QIBM/UserData/WebSphere/AppServer/<version>/<edition>/profiles/<profileName>/properties/ssl.client.props'
- Option 2 to edit.
- Locate the "com.ibm.ssl.protocol" property under the SSL Alias "DefaultSSLSettings" and change the value to "TLSv1.3,TLSv1.2". Set this value to the same value you set the application server protocol to use.
com.ibm.ssl.alias=DefaultSSLSettings
com.ibm.ssl.protocol=TLSv1.3,TLSv1.2
- After you make the change, press F3 twice to save and exit.
- The WAS v8.5 and v9.0 IBM i Web Server plug-ins fully support the TLSv1.3 protocol at WAS v8.5.5.20 and later and WAS v9.0.5.6 and later.
- In a mixed cell configuration, careful consideration is required before enabling TLSv1.3 and TLSv1.2 to ensure communications.
- To change DMGR and all NODES to use TLSv1.3, first make changes with only the DMGR running, then restart the DMGR process, and sync each node from the command line. Then bring the DMGR and NODES up. For detailed steps, refer to the technote, "How can I configure WebSphere Application Server SSL protocol to use TLSv1.2 ONLY?", replacing TLSv1.2 with TLSv1.3 & TLSv1.2.
- The TLSv1.3 & TLSv1.2 protocols are fully supported by the IBM i OS and IBM HTTP Server 5770-DG1 LPP at IBM i 7.3 (with the minimum IBM i Group PTF levels) and later.
- NOTE: The IBM i OS must meet the minimum Group PTF levels and the TLSv1.3 & TLSv1.2 protocols must be enabled for the IBM i OS and IBM HTTP Server instance in order for it to be used by an IBM HTTP Server instance on the IBM i OS.
