you're right... What I ran was this:

def PrepareHash(HashStr):
  while len(HashStr) > 0:
byte = HashStr[0:2]
print byte,int(byte,16),chr(int(byte,16)) # & 0xff
HashStr = HashStr[2:]
  return byte

def Main():
  HashStr = "c17ce186ab94eeb0de8ae3b5b751a7c4d8e9edeb"
  HashStr = PrepareHash(HashStr)
  print "Prepared HashStr :",HashStr

Main()

Exactly... which is the problem.  I don't know what the heck the [byte]
in front of a variable does.  I may have to get into the java list.
YUK!

thanks.

I know what you're saying, John.  That's what is encryptic about this
whole thing.  The [byte] call in front of any variable will turn the
variable value to a "byte".  If you look at the code at the java code
at the beginning,

>>>   byte[] retBuf = new byte[inString.length()/2];

this retBuf is an array of bytes.  Whatever that means in java.  And
yes, that is the right output or result.  Hmmm, maybe an array of bytes
will turn into retBuf[0]+retBuf[0] = the first letter... H

Well, how can I get that exact answer from python?

Well, now that you say that, it may be that there is a space there.
H, let me try that again...

yep, you're right...
