Package de.schlichtherle.util.zip Description

A drop-in replacement for the classes in the package java.util.zip which read and write ZIP files.

The classes in this package read and write ZIP files according to a subset of PKWARE's ZIP File Format Specification , Version 6.3.2 from September 28, 2007. The subset has been selected in order to achieve the following objectives:

• Full interoperability with ZIP files read or written by the package java.util.zip of Sun's Java SE 6 implementation.
• Support for reading and writing ZIP64 extensions with the following restrictions:
  1. The offsets in ZIP64 files must respect a preamble if present, i.e. they must by exact. This is in contrast to ZIP32 files where the offsets do not need to respect a preamble if present. Preambles are primarily used to contain self extracting (SFX) executable code.
  2. The maximum file size is Long.MAX_VALUE (9223372036854775807L).
  3. The maximum number of entries in the Central Directory is Integer.MAX_VALUE (2147483647).
• Support for arbitrary character sets, in particular IBM Code Page 437 (alias IBM PC) for PKZIP compatibility and UTF-8 for Java Archive (JAR) compatibility. Note that using any other character set except CP437 or UTF-8 is strongly discouraged because it will result in interoperability issues with third party tools, especially when interchanging archive files between different locales!
• ZipFile supports reading archive data from the random access read only interface ReadOnlyFile, which allows to read archive data from complex data sources such as RAES encrypted ZIP files directly without the need to decrypt these to a temporary file first (see package de.schlichtherle.crypto.io.raes).
