<H1>7z Format</H1>
<P><B>7z</B> is the new archive format, providing high compression ratio.</P>
<P>The main features of <B>7z</B> format:</P>
<UL>
<LI>Open architecture
<LI>High compression ratio
<LI>Strong AES-256 encryption
<LI>Ability of using any compression, conversion or encryption method
<LI>Supporting files with sizes up to 16000000000 GB
<LI>Unicode file names
<LI>Solid compressing
<LI>Archive headers compressing
</UL>
<P><B>7z</B> has open architecture, so it can support any new compression methods.
Now the following methods are integrated to <B>7z</B>:</P>

<P><B>LZMA</B> is default and general compression method of <B>7z</B> format. The main features of <B>LZMA</B> method:</P>
<UL>
<LI>High compression ratio
<LI>Variable dictionary size (up to 4 GB)
<LI>Compressing speed: about 1 MB/s on 2 GHz CPU
<LI>Decompressing speed: about 10-20 MB/s on 2 GHz CPU
<LI>Small memory requirements for decompressing (depend from dictionary size)
<LI>Small code size for decompressing: about 5 KB
<LI>Supporting multi-threading and P4's hyper-threading
</UL>
<P><B>LZMA</B> compression algorithm is very suitable for embedded applications.
<B>LZMA</B> is released under the terms of the GNU LGPL. <B>LZMA</B> is also
available under a proprietary license for those who can not use the GNU LGPL in
their code. If you want to use <B>LZMA</B> code, you can ask consultations,
custom code programming and required developer licenses
from page for support:
<A href="support.html">Send message to LZMA developer</A>.
Check also information about <A href ="sdk.html">LZMA SDK</A>.</P>
<P>7-Zip also supports encryption with AES-256 algorithm.
This algorithm uses cipher key with length of 256 bits. To create that key 7-Zip
uses derivation function based on SHA-256 hash algorithm.
A key derivation function produces a derived key from text password defined by user.
For increasing the cost of exhaustive search for passwords 7-Zip uses big number
of iterations to produce cipher key from text password.</P>
<P><B>7z</B> is a part of <A href="./">7-Zip</A> program distributed under the GNU LGPL.
You can download <B>7-Zip</B> sources and binaries from <A href ="download.html">Download Page</A>.</P>
<p>Applications that support <B>7z</B> archives: WinRAR, PowerArchiver, TUGZip, IZArc.</p>
