Use the ENCRYPTION parameter statement to allow the selection of a subset of the supported algorithms to use for this port. Each z/OS® system level supports a specific set of encryption algorithms.
The ENCRYPTION statement can be coded in the TELNETGLOBALS, TELNETPARMS, or PARMSGROUP statement blocks. See Rules for Telnet parameter statements and security parameters for more information about the hierarchy of parameter values.
Restriction: The ENCRYPTION/ENDENCRYPTION block applies only to a Telnet SECUREPORT that serves SSLv3/TLSv1 and later clients.
