<h2>How To Become A Consortium Member</h2>

<p>
Membership in the SQLite Consortium is via
<a href="consortium_agreement-20071201.html">contract</a> with
[https://www.hwaci.com/ | Hipp, Wyrick &amp; Company, Inc.].
Please call +1.704.948.4565 during US east-coast business hours

All of the code and documentation in SQLite has been dedicated to the
[http://en.wikipedia.org/wiki/Public_Domain|public domain]
by the authors.
All code authors, and representatives of the companies they work for,
have signed affidavits dedicating their contributions to
the public domain and originals of
those signed affidavits are stored in a firesafe at the main offices
of <a href="https://www.hwaci.com">Hwaci</a>.
Anyone is free to copy, modify, publish, use, compile, sell, or distribute
the original SQLite code, either in source code form or as a compiled binary,
for any purpose, commercial or non-commercial, and by any means.
</p>

<p>
The previous paragraph applies to the deliverable code and documentation

internet.  Every line of code can be traced back to its original
author, and all of those authors have public domain dedications
on file.  So the SQLite code base is clean and is
uncontaminated with licensed code from other projects.

<h2>Obtaining An License To Use SQLite</h2>

<p>

     SQLite. </li>
<li> Your legal department tells you that you have to purchase a license.
     </li>
</ul>

<p>
If you feel like you really need to purchase a license for SQLite,
<a href="https://www.hwaci.com/">Hwaci</a>, the company that employs 
all the developers of SQLite, will 
<a href="https://www.hwaci.com/cgi-bin/license-step1">sell you
one</a>.
All proceeds from the sale of SQLite licenses are used to fund
continuing improvement and support of SQLite.

  is an aviation-grade test suite for SQLite. SQLite developers 
  can run TH3 on specialized hardware and/or using specialized

<h2>Further Information</h2>

sign-up</a>, but you can simply send an email message to
<a href="mailto:sqlite-users@mailinglists.sqlite.org">sqlite-users@mailinglists.sqlite.org</a> and
your question will probably appear on the mailing list in about 24 hours.
(Questions from non-members are moderated, which is the reason for the
24-hour delay.)

<p>If you do not want to discuss your issues on a public and open forum, an
<a href="https://www.hwaci.com/sw/sqlite/ams.html">Annual Maintenance 
Subscription</a> or "AMS" might
serve your needs better.
An AMS entitles you to private email support directly from the developers of
SQLite.  The level of support with an AMS is similar to the support one
gets from the public mail list except that an AMS includes a unilateral 
promise of non-disclosure, so with an AMS you can discuss your issues
with the SQLite developers in private, without the whole world watching.
An AMS costs $1500 per year.</p>

<p>Users with more advanced support needs can opt for a
<a href="https://www.hwaci.com/sw/sqlite/tech.html">Technical Support
Agreement</a>.
Technical support agreements are customized to the needs of each
individual client, but generally include direct telephone support
and priority handling of issues and bugs.  Guaranteed response time
is available as an option.  The cost of
technical support varies but is generally
in the range of $8000 to $35000 per year.</p>

<p>If SQLite is "mission critical" to your company, then you may
want to becoming an 
<a href="https://www.hwaci.com/sw/sqlite/member.html">SQLite Consortium 
Member</a>.  The SQLite
Consortium is a collaboration of companies who sponsor ongoing development
of SQLite in exchange for enterprise-level technical support, on-site
visits from the SQLite developers, unlimited access to all licensed
products, and strong guarantees that SQLite will remain in the public
domain, free and independent, and will not come under the control of
a competitor.  The cost of consortium membership is $75000 per year.</p>

<h2>Software Licenses</h2>

<p>The SQLite source code is in the 
<a href="https://www.sqlite.org/copyright.html">public domain</a>,
and is free for use
by anyone and for any purpose.  No license is required.  However, some
users desire a license so that they can have warranty of title, or just
because their company lawyers say they need one.  A
<a href="https://www.hwaci.com/cgi-bin/license-step1">perpetual license</a> 
and warranty
of title for the core SQLite source code is available for this purpose.</p>

<p>The 
<a href="https://www.hwaci.com/cgi-bin/see-step1">SQLite Encryption
Extension (SEE)</a>,
the <a href="https://www.hwaci.com/cgi-bin/zipvfs-step1">ZIPVFS Extension</a>,
and the <a href="https://www.hwaci.com/cgi-bin/scerod-step1">Compressed and
Encrypted ReadOnly Database (CEROD)</a> extension are enhanced versions 
of SQLite that handle encrypted
and/or compressed databases.  SEE can read and write encrypted databases.
SEE encrypts all database content, including metadata, so that the database
file appears as white noise.  ZIPVFS 
compresses the database on-the-fly using application-supplied 
compression and decompression functions.

<p>The core SQLite library found on this website is in the
<a href="copyright.html">public domain</a>.  But there also exist
proprietary, licensed extensions to SQLite.</p>

<ul>
<li><p>
The [https://www.hwaci.com/sw/sqlite/see.html | SQLite Encryption Extension (SEE)]
will read and write database file encrypted using
128-bit or 256-bit AES.</p></li>

<li><p>
The [https://www.hwaci.com/sw/sqlite/cerod.html | SQLite Compressed and Encrypted Read-Only Database (CEROD)]
extension will read a database file that is both compressed
and encrypted.</p></li>

<li><p>
The [https://www.hwaci.com/sw/sqlite/zipvfs.html | ZIPVFS]
extension will both read and write database files that is both compressed and optionally
encrypted using application-supplied compression and encryption routines.</p></li>

vectors for SQLite that verify the operation of SQLite in an
