_ZipDecryptera Class to handle decryption of files stored within a ZIP archive.
ZIP supports a password-based form of encryption. Even though known
plaintext attacks have been found against it, it is still useful
to be able to get data out of such a file.
Usage:
zd = _ZipDecrypter(mypwd)
plain_char = zd(cypher_char)
plain_text = map(zd, cypher_text)

ZIP encryption uses the CRC32 one-byte primitive for scrambling some
internal keys. We noticed that a direct implementation is faster than
relying on binascii.crc32().

z = ZipFile(file, mode="r", compression=ZIP_STORED, allowZip64=True)
file: Either the path to the file, or a file-like object.
If it is a path, the file will be opened and closed by ZipFile.
mode: The mode can be either read 'r', write 'w', exclusive create 'x',
or append 'a'.
compression: ZIP_STORED (no compression), ZIP_DEFLATED (requires zlib),
ZIP_BZIP2 (requires bz2) or ZIP_LZMA (requires lzma).
allowZip64: if True ZipFile will create files with ZIP64 extensions when
needed, otherwise it will raise an exception when this would
be necessary.

name is a string for the file name within the ZIP file, or a ZipInfo
object.
mode should be 'r' to read a file already in the ZIP file, or 'w' to
write to a file newly added to the archive.
pwd is the password to decrypt files (only used for reading).
When writing, if the file size is not known in advance but may exceed
2 GiB, pass force_zip64 to use the ZIP64 format, which can handle large
files. If the size is known in advance, it is best to pass a ZipInfo
instance for name, with zinfo.file_size set.

|| dS )a Add all files from "pathname" to the ZIP archive.
If pathname is a package directory, search the directory and
all package subdirectories recursively for all *.py and enter
the modules into the archive. If pathname is a plain
directory, listdir *.py and enter all modules. Else, pathname
must be a Python *.py file and the module will be put into the
archive. Added modules are always module.pyc.
This method will compile the module.py into module.pyc if
necessary.
If filterfunc(pathname) is given, it is called with every argument.
When it is False, the file or directory is skipped.

| fS )a Return (filename, archivename) for the path.
Given a module name path, return the correct file path and
archive name, compiling if necessary. For example, given
/python/lib/string, return (/python/lib/string.pyc, string).
