Hi All,

I am currently trying to make a HTTPS call from ZOS.
My organization policy has streamlined ZOS Connect EE as the setup for consuming API . But the infrastructure like WAS server,Gateway will take time. Hence i stumbled upon z/OS client web enablement toolkit as quick win. I was able to make HTTP calls without much of a setup.

My query is if there a downside of using z/OS client web enablement toolkit instead of ZOS connect EE. I will be grateful If someone could help me understand the pros and cons of both ? I will have to present a case to defend usage of z/OS client web enablement toolkit.

I am able to connect to http endpoints and able to get the response. But getting the errors with https calls. Below are the verbose log about the errors.

Hello,

You have to open a new topic for this.
Quote:
No SSL cipher specifications reason code 402.


This gives a hint, there is no common cipher algorithms that is common between the client and server.

Ciphers are encryption algorithms,
The client(the system from which you are initiating connection) will have a configuration that says, here are the list of algorithms that I can communicate with.

The server(the system to which you are trying to connect) it will have configuration that says, here are the list of algorithms that server can communicate.

There should be atleast one cipher in common between client and server, else you would get this error.
