Introduction

The ZipArchive Library incorporates third-party code for its functionality. All used code is known to be patent-free and can be reused in commercial applications.

Used Third-Party Code

The Zlib Library by Jean-loup Gailly and Mark Adler

  • The Zlib library provides deflate compression and decompression functionality.
  • The home page of the library is at http://www.zlib.net.
  • The licensing information can be found in the zlib.h file and is provided below.

The bzip2 data compressor by Julian Seward

  • The bzip2 data compressor provides lossless, block-sorting data compression and decompression functionality.
  • The home page of the compressor is at http://www.bzip.org.

IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

WARNING:

This program and library (attempts to) compress data by performing several non-trivial transformations on it. Unless you are 100% familiar with *all* the algorithms contained herein, and with the consequences of modifying them, you should NOT meddle with the compression or decompression machinery. Incorrect changes can and very likely *will* lead to disastrous loss of data.

DISCLAIMER:

I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.

Every compression of a file implies an assumption that the compressed file can be decompressed to reproduce the original. Great efforts in design, coding and testing have been made to ensure that this program works correctly. However, the complexity of the algorithms, and, in particular, the presence of various special cases in the code which occur with very low but non-zero probability make it impossible to rule out the possibility of bugs remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.

That is not to say this program is inherently unreliable. Indeed, I very much hope the opposite is true. bzip2/libbzip2 has been carefully constructed and extensively tested.

PATENTS:

To the best of my knowledge, bzip2/libbzip2 does not use any patented algorithms. However, I do not have the resources to carry out a patent search. Therefore I cannot give any guarantee of the above statement.

AES Implementation by Dr Brian Gladman

  • The used AES implementation provides strong encryption support.
  • The code is based on the source code written by Dr Brian Gladman and available at http://www.gladman.me.uk/.
  • The licensing information is provided in all files that reuse the AES code (e.g. in the Aes.h file) and is provided below.
