Re: MD5/SHA hash

John:

Before this going farther, can you clarify what you mean when you say 
"I've tried CCSID 16488 and 1200"? Was that a typo? Even if so, how were 
you specifying CCSID 16488 _and_ 1200? When you wrote "and", was that 
just your choice of phrasing? (UCS-2 CCSID is 13488 -- code page 1200.)
