Re: File encryption

I've already place a basic module on the CBT tape. File 529. It uses AES
and the ICSF subroutines. I never tried it without Crypto hardware, but
maybe it would work, since AES keys are processed as clear keys. This
changes with the Z9 machine.

You might be right. I haven't looked at the doc in a while. Depending on
how much data you are encrypting you might be taking a performance hit
since the encryption and decryption has to be done in software without
hardware assists.

Nope, it's a 7060-H30, we definitely don't have a crypto on it. We're
going to z890 late this year/early next and we'll be specifying crypto
options on that.

It sounds like I might be in for a disappointment with MegaCryption
then.. I was getting the impression from their brochure that it would do
field-level. :-(

Well both IBM's product and MegaCryption work on a file by file basis.
They don't do anything for fields within records.

What model mainframe do you have? You might have the crypto-coprocessors
available and not even know it.
