Looking at z/Web server more closely, it appears to have a MAKEKEY comman d with options: -E -- display (to stdout) the certified public and private keys (DER
encoded) in keyfile. -I -- read fron stdin a public and private key pair (DER encoded) and insert in keyfile. (I haven't tested them, though.) There doesn't appear to be anything in SSLADMIN to import or export key pairs, though. Even if I could export the Linux file & turn it into a CMS file, I ha ve my doubts that z/Web could read it.
