I am trying to get results from Mathematica's Hash function (for hash type 
"MD5") that are consistent with the results obtained using "openssl md5" in 

The particular example I would like to reproduce is on, where

"Hello, Avatar!:0"

hashes to (for hash type "MD5")


In Mathematica 6 (Windows Vista, Intel hardware), doing the obvious

Hash["Hello, Avatar!:0", "MD5"] // BaseForm[#, 16] &

I get the following result


This is not the same as expected. Does anyone know how to get consistent
