Have an idea for another XCOM SSL topic? Let us know. Thanks, Nancy CA Support
These tech docs were written for OpenSSl.
I do not know if you already have certificates for OpenSSl and want to convert them.
The 12.0 online documentation has a lot of information in it about converting OpenSSl certificates to SystemSSl.
There is also this new KB article which has step by step instructions:Renewal of the OpenSSL client and server certificates used with CA XCOM for z/OS
Please let me know if these are what you ned.
