zlib.adler32(), zlib.crc32(), and binascii.crc32() always return 32-bit unsigned integer in Python 3. binascii.crc_hqx() almost always returns 16-bit unsigned integer. But there is an exception. The result can negative only when arguments of binascii.crc_hqx() are empty bytes and negative integer. This looks as a bug and should be fixed. But may be no need to apply changes to maintained releases. |
