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!
Vern
