@Immutable
public class CheckedZipDriver
extends ZipDriver

An archive driver for ZIP files which checks the CRC-32 values for all ZIP entries in input archives. The additional CRC-32 computation makes this class slower than its super class.

If there is a mismatch of the CRC-32 values for a ZIP entry in an input archive, the InputStream.close() method of the corresponding stream for the archive entry will throw a CRC32Exception. Other than this, the archive entry will be processed normally. So if just the CRC-32 value for the entry in the archive file has been modified, you can still read its entire contents.
