Error description
As of CICS TS 6.3 the use of 2-digit ciphers has been removed. There is still code in DFHEIWB that makes a call to validate a 2-digit cipher list. This call is redundant as CICS will never use a 2-digit cipher. At z/OS 3.2, the validation will always fail with message DFHSO0145, this causes the WEB OPEN command to fail with INVREQ RESP2=137.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: A WEB OPEN command specifying CIPHERS * * fails on a z/OS 3.2 system with abend * * AEIP (INVREQ) and EIBRESP2 = 137. * **************************************************************** A WEB OPEN command specifying the CIPHERS attribute fails with abend AEIP (INVREQ) and RESP2=137 on a z/OS 3.2 system. This is because as of z/OS 3.2, the system SSL default 2-digit ciphers list is now empty as 2-digit ciphers are no longer supported. CICS still contains code to validate ciphers specified on the CIPHERS attribute of a WEB OPEN command against the system SSL default list. This validation will always fail given the system SSL default list is now empty. Note that as of CICS TS 6.3, the CIPHERS attribute on the WEB OPEN command has been deprecated. CICS TS 6.3 programs will not compile with this attribute. However older compilations of programs can still contain the CIPHERS parameter.
Problem conclusion
The redundant validation code has been removed.
