SHA-256 Vs SHA-1 & AES Vs DES

["Shan Harter" <Shan@xxxxxxxxxxxxx>]

Hello,

I originally sent this direct to Dale but perhaps the best method is to
submit to the group so I will resubmit here.
 
In evaluation of the long term aspects and potential future
vulnerabilities to existing hash and symmetric key algorithms, are there
"phase-out" plans on the
horizon to replace SHA-1 and DES as it relates to ebXML or AS2 - AS3? 
 
Is consideration being applied to SHA-256 or SHA-512?
 
See
 
http://www.fcw.com/fcw/articles/2005/0207/web-hash-02-07-05.asp
 
 
Also is AES being considered to replace DES?
 
Regards,
 
Shan
