Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Support for CCM algorithm in SystemSSL

For TLS1.3 there are 5 official supported ciphers:

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256
TLS_AES_128_CCM_8_SHA256
TLS_AES_128_CCM_SHA256

And zOS SystemSSL does not support:
TLS_AES_128_CCM_8_SHA256
TLS_AES_128_CCM_SHA256

To increase interoperability with other peer systems CCM cipher would be appreciated to have all officially supported ciphers for TLS1.3 as well in zOS.
