NOTICE:
-------
Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the license agreement which
accompanied, or was contained in, the Program for which you are obtaining
the PTF.  You are not authorized to install or use the PTF except as part
of a Program for which you have a valid Proof of Entitlement.

APAR Error Description / Circumvention

-------------------------------------------------
Clear key RSA processing performed by a 4765 cryptographic
coprocessor can produce the wrong results when using keys that
are greater than 2048 bits.

CORRECTION FOR APAR 'SE44942' :
-------------------------------
There was an error in the firmware.  The problem has been fixed.

CIRCUMVENTION FOR APAR 'SE44942' :
----------------------------------
None.


Activation Instructions


None.




Special Instructions

After applying or removing the PTF, if device descriptions for one
or more 4765 Cryptographic Coprocessors are varied on, vary them
off and then back on using either the Vary Configuration (VFYCFG)
or Work with Configuration Status (WRKCFGSTS) CL commands.

If no device descriptions for a 4765 Coprocessor are varied on,
no descriptions for a 4765 Coprocessor exist, or no 4765 Coprocessor
is installed, nothing further needs to be done.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
