Iter_bytes( chunk_size = 65536)For file_name, file_size, unzipped_chunks in stream_unzip( zipped_chunks(), password = b'my-password'):The file name and file size are extracted as reported from the file.

Note that due to nature of the ZIP file format, some incorrect passwords would not raise this exception, and instead raise a DataError, or even in pathalogical cases, not raise any exception.An incorrect password was supplied for a legacy (ZipCrypto/Zip 2.0) encrypted file.An incorrect password was supplied for an AES encrypted file.An issue with the ZIP bytes themselves was encountered.A file in the ZIP uses features that are unsupported.An error in the deflate-compressed data meant it could not be decompressed.The HMAC integrity check on AES encrypted bytes failedThe CRC32 integrity check on decrypted and decompressed bytes failed.Each section of a ZIP file starts with a signature, and an unexpected one was encountered.Metadata known as extra that some ZIP files require is missing.Metadata known as extra that some ZIP files require is present, but too short.Metadata known as extra that some ZIP files require is present, long enough, but holds an invalid value.AES key length specified in the ZIP is not any of 1, 2, or 3 (which correspond to 128, 192, and 256 bits respectively). Exception hierarchyBase class for all explicitly-thrown exceptionsA file requires a password, but it was not supplied.A file is legacy (ZipCrypto/Zip 2.0) encrypted, but a password was not supplied.A file is AES encrypted, but a password was not supplied.An incorrect password was supplied. Other exceptions are in the stream_unzip module, and derive from its UnzipError which itself derives from Python's built-in ValueError. ExceptionsExceptions raised by the source iterable are passed through stream_unzip unchanged.
