If your https target has a determinable ip address port combination, then you can let the z/os networking guys onfigure SSL for you by using AT-TLS. Then you don't need to change anything on your program, the encryption will be transparent to your application and from the z/os tcpip stack to the endpoint. There will be no encryption internal to z/os from your application to the z/os tcpip stack. So ask for an AT-TLS configuration. Hope it helps,Denis.

The program (subroutine) is written in C and uses the standard TCP/IP socket interface, available in the classical z/OS environment. I am doing all the conversion work myself, and I build the necessary HTTP headers, and analyze them on return. This works without problems. When running under CICS, I provide the same interface to the callers, but I use the EXEC CICS WEB CONVERSE calls instead (because CICS does not allow me to do standard socket calls, when under CICS control). Now the problem is: I am limited to HTTP at the moment, but customer's politics requires me to do HTTPS in the middle and long term. I have no idea what I need to do to provide HTTPS communication in the batch and in the CICS case; what are my options and what is the easiest migration path? Thank you all, kind regards Bernd ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
