No. The decode method on string objects is removed, you can only
*encode* strings, but not decode them.

The problem is this:

py> hashlib.sha1(b"Hallo").hexdigest().decode("hex")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'decode'
