Walt, 

Thanks for your response.  We read something similar about DSA not being
usable for SSL encryption.

We have gotten further info from CA. It seems like I left something out of
my post that was relevant.  We are still running z/OS 1.9.  

It seems that with z/OS 1.9 the max keysize is 1024 without the PCI crypto
card.  See the RACF manual from z/OS 1.9
http://publibz.boulder.ibm.com/epubs/pdf/ichza480.pdf  page 291 for the
size(keysize) parameter of RACDCERT.  

However with z/OS 1.10 or later the max keysize is 4096.  See the RACF
manual form z/OS 1.10 http://publibz.boulder.ibm.com/epubs/pdf/ichza490.pdf
page 330 & 331 for the size(keysize) parameter of RACDCERT GENCERT. 

Someone suggested trying to request a certificate with 2048 bit key and RSA
from another machine that supports this and trying to install that
certificate in a TSS keyring on our system and then try to use it.  If that
doesn't work, I guess our other option is to tell our clients to tolerate an
expired certificate until we can get to a new release of z/OS.
