My understanding is that there are a couple TLS 1.3 options for Java on z/OS (not necessarily in order):
1. Assuming you have at least the IBM SDK/JRE for Java, Version 8, Service Release 6, Fix Pack 25, you should be able to enable TLS 1.3 support using these instructions: https://www.ibm.com/docs/en/sdk-java-technology/8?topic=customization-enabling-tls-13 Please note you'll need to use the IBMJCEPlus provider, as mentioned. Fix Pack 25 is quite recent, released in February, 2021. Fix Pack 31 is the latest available update, as I write this. 2. If you're on z/OS 2.4 or higher, you should be able to use z/OS AT-TLS for TLS 1.3. More information is available here (z/OS 2.4 link): https://www.ibm.com/docs/en/zos/2.4.0?topic=security-tls-support-tls-v13 - - - - - - - - - - Timothy Sipples I.T.
