Kathey Marsden commented on DERBY-962:
--------------------------------------


I don't have any more comments on this patch. It looks good to me.  Thanks for putting the
summary in the test. I think that will really help anyone  looking at this in the future.
  It would be great if someone else could look at this patch too.  I will check in first thing
tomorrow  if we don't get any more comments.


Thanks

Kathey

> Currently in the client, if userid and password are set in the connection url, the default
security mechanism is upgraded to USRIDPWD (which is clear text userid and password).  This
seems to be a security hole here. 
> Current client  driver supports encrypted userid/password (EUSRIDPWD) via the use of
DH key-agreement protocol - however current Open Group DRDA specifications imposes small prime
and base generator values (256 bits) that prevents other JCE's  (apt from ibm jce) to be used
as java cryptography providers.  
> Some thoughts:
> -- client can make a check to see if it the jvm it is running in supports the encryption
necessary for EUSRIDPWD. If it supports, then the client can upgrade to EUSRIDPWD. 
> -- if the jvm the client is running is , doesnt support encryption requirements for EUSRIDPWD,
then the security mechanism will be set to USRIDPWD.
> -- DERBY-528 will add support for strong userid and password which is another option
to send encrypted passwords across the wire. When this gets added, maybe this can be considered
as one of the upgrade options after EUSRIDPWD.
