Clearly it fell short of the mark insofar as it easily misled you
and me. A clarification might be helpful, such as a paraphrase
of John E.'s words to:
Data which ICSF has compressed and encrypted can be decrypted
but not uncompressed by the Encryption Facility Client.
That's not quite right either, gil.
I thought it was.
Remember that there are two pieces involved. The IBM Encryption
Facility for z/OS, and the separate Encryption Facility Client.
Is "The IBM Encryption Facility for z/OS" different from ICSF?
If so, I'm quite wrong.
ICSF is completely different from IBM Encryption Facility for z/OS.
ICSF is base element of z/OS, kind of device driver providing set of API
calls as well as some administration utilities.
IBM Encryption Facility for z/OS is separate (fee-based) product. This
product uses ICSF in background. It is set of tools to encrypt data on
the disk or tape. These tools use ICSF API under the cover.
