Radoslaw, One day I might get around to doing what you need. It's on my "to do" list. In the interim there is a routine here, https://rsclweb.com/downloads/#CSFXFER-position which will allow you to transfer DES keys using a shared symmetric transport key. You may find that Eysha Powers has created some routines to do what you wish.

Encrypt like everyone is.’ -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Radoslaw Skorupka Sent: 14 January 2022 18:00 To: [email protected] Subject: ICSF key exchange scenario Let's assume two z/OS images and some data exchange. One of possible methods is symmetric encryption. However that requires key exchange. I have the following idea: 1. Both sides create asymetric key. 2. Public keys are exported and exchanged. 3. One side encrypt symm key using public key of another side. 4. Second side decrypt symm key using it's own private key. Does it make sense? Any hints? What services to use in steps 4. and 5. ? -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
