[New-bugs-announce] [issue4871] zipfile can't decrypt

[Glade Diviney]

New submission from Glade Diviney <gladed at sybase.com>:

If a password is supplied using zpifile.read(objName, password), a 
TypeError occurs:

  File "C:\Program Files\Python30\lib\zipfile.py", line 420, in __init__
    self._UpdateKeys(p)
  File "C:\Program Files\Python30\lib\zipfile.py", line 424, in 
_UpdateKeys
    self.key0 = self._crc32(c, self.key0)
  File "C:\Program Files\Python30\lib\zipfile.py", line 413, in _crc32
    return ((crc >> 8) & 0xffffff) ^ self.crctable[(crc ^ ch) & 0xff]
TypeError: unsupported operand type(s) for ^: 'int' and 'str'

This is resolved in zipfile.py by replacing this line in __init__:
             self._UpdateKeys(ord(p))
