<h3>Proprietary SQLite Extensions</h3>

<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, written and maintained
by the original developer.</p>

The [ | SQLite Encryption Extension (SEE)]
will read and write database file encrypted using
128-bit or 256-bit AES.</p></li>

The [ | SQLite Compressed and Encrypted Read-Only Database (CEROD)]
extension will read a database file that is both compressed
and encrypted.</p></li>

The [ | 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>

The [TH3 | Test Harness #3 (TH3)] is an alternative set of test
vectors for SQLite that verify the operation of SQLite in an
as-deployed configuration on embedded platforms with
[test coverage | 100% branch test coverage].

<tcl>hd_fragment mailinglists {mailing lists}</tcl>
<h3>Mailing Lists</h3>
<p>Three separate mailing lists have been established to help support

<li><a href="">
sqlite-announce</a> - announcements of new
releases or significant developments.</li>
<li><a href="">
sqlite-users</a> - general user discussion; most postings belong here.</li>
<li><a href="">
sqlite-dev</a> - developer conversations; for people who have or aspire to
have write permission on the SQLite source code repository.</li>

Most users of SQLite will want to join the
<a href="">
sqlite-announce</a> list and many will want to join the
<a href="">
sqlite-users</a> list.  The
<a href="">
sqlite-dev</a> list is more specialized and appeals to a narrower audience.
Off-site archives of the
<a href="">
sqlite-users</a> list are available at:

<h3>Direct E-Mail To The Author</h3>

Use the mailing list.
Please do <b>not</b> send email directly to the author of SQLite
<li>You have or intend to acquire a professional support contract
as described above, or</li>
<li>You are working on an open source project.</li>
You are welcomed to use SQLite in closed source, proprietary, and/or
commercial projects and to ask questions about such use on the public
mailing list.  But please do not ask to receive free direct technical
support.  The software is free; direct technical support is not.
