_ZipDecrypterc B sD e Z d Z d � Z e � Z d � Z d � Z d � Z d � Z RS( s 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=False)
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" or append "a".
compression: ZIP_STORED (no compression) or ZIP_DEFLATED (requires zlib).
allowZip64: if True ZipFile will create files with ZIP64 extensions when
needed, otherwise it will raise an exception when this would
be necessary.

s, 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.pyo or module.pyc.
This method will compile the module.py into module.pyc if
necessary.

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=False)
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" or append "a".
compression: ZIP_STORED (no compression) or ZIP_DEFLATED (requires zlib).
allowZip64: if True ZipFile will create files with ZIP64 extensions when
needed, otherwise it will raise an exception when this would
be necessary.

s, 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.pyo or module.pyc.
This method will compile the module.py into module.pyc if
necessary.
