Regression tests showed that the CCA cipher key function which generates an CCA cipher key with given clear key value does not work correctly. At parsing the reply CPRB two limits are wrong calculated resulting in rejecting the reply as invalid with s390dbf message "_ip_cprb_helper reply with invalid or unknown key block".
