|
|
The last versions of these <span class="emphasis"><em>legacy</em></span> databases are:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
|
|
cert8.db for certificates
|
|
</p></li><li class="listitem"><p>
|
|
key3.db for keys
|
|
</p></li><li class="listitem"><p>
|
|
secmod.db for PKCS #11 module information
|
|
</p></li></ul></div><p>BerkeleyDB has performance limitations, though, which prevent it from being easily used by multiple applications simultaneously. NSS has
|
|
some flexibility that allows applications to use their own, independent database engine while keeping a shared database and working around the access issues. Still, NSS
|
|
requires more flexibility to provide a truly shared security database.</p><p>In 2009, NSS introduced a new set of databases that are SQLite databases rather than
|
|
BerkleyDB. These new databases provide more accessibility and performance:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
|
|
cert9.db for certificates
|
|
</p></li><li class="listitem"><p>
|
|
key4.db for keys
|
|
</p></li><li class="listitem"><p>
|
|
pkcs11.txt, which is listing of all of the PKCS #11 modules contained in a new subdirectory in the security databases directory
|
|
</p></li></ul></div><p>Because the SQLite databases are designed to be shared, these are the <span class="emphasis"><em>shared</em></span> database type. The shared database type is preferred; the legacy format is included for backward compatibility.</p><p>By default, the tools (<span class="command"><strong>certutil</strong></span>, <span class="command"><strong>pk12util</strong></span>, <span class="command"><strong>modutil</strong></span>) assume that the given security databases follow the more common legacy type.
|
|
Using the SQLite databases must be manually specified by using the <span class="command"><strong>sql:</strong></span> prefix with the given security directory. For example:</p><pre class="programlisting"># pk12util -i /tmp/cert-files/users.p12 -d sql:/home/my/sharednssdb</pre><p>To set the shared database type as the default type for the tools, set the <code class="envar">NSS_DEFAULT_DB_TYPE</code> environment variable to <code class="envar">sql</code>:</p><pre class="programlisting">export NSS_DEFAULT_DB_TYPE="sql"</pre><p>This line can be set added to the <code class="filename">~/.bashrc</code> file to make the change permanent.</p><p>Most applications do not use the shared database by default, but they can be configured to use them. For example, this how-to article covers how to configure Firefox and Thunderbird to use the new shared NSS databases:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
