Re: Cryptographic algorithm support by OS level

Yowsie. Cryptography is confusig enough without adding this to the mix! Here's hoping it's finally resolved!

(That sounds like another software company, not like IBM, by the way.)

To all who might need this information - turns out that before V5R4,
licensed product 5722-AC3 was required to use the encryption
algorithms.
Apparently the export restriction was lifted, and V5R4 and later have
the algorithms in the operating system - this is why 57xx-AC3 was
pulled, I suppose.

Now another wrinkle - we DO have AC3 on our V5R1 box - yet the extra
algorithms did not show up. Turns out there was a problem where the MI
stuff that AC3 modified/added could get lost, usually when moving from
one machine to another.

One solution is to SAVLICPGM/DLTLICPGM/RSTLICPGM - the note I saw said
that the self-certificates had to be rebuilt.

Hi, Vern:

I compiled and ran your program on V5R2 and the results are the same

as

what you show for V5R1.

Hi all

Scott Klement has some code that displays which algorithms are

supported

on the release you are running. At V5R1, there are only 4 of them

(MAC,

MD5, SHA-1, and DES (two-way).

At V5R3 there are 10 more.

I need to know what the algorithms are at V5R2 - maybe it's

documented

somewhere, I looked in MTU - nothing there. I don't have the MI docs

for

CIPHER at V5R2, InfoCenter doesn't have them anywhere that're

obvious to me.

Here is an amended version of Scott's code, usable at V5R1 and on -

his

takes advantage of LIKEDS in data structure subfields, which wasn't
available that far back.

Maybe someone still has a V5R2 system/partition - if so, please

compile

and run this code and let me know the results.

Much appreciated!
