Use the sha.update method. Something like:
ctx = sha.new()
while True:
x = f.read(16384)
if not x: break
ctx.update(x)
hash = ctx.digest()

There are some modules around for this. Unless you're trying to
interoperate with something that needs them, or have some other reason
to want them, I wouldn't bother.
