    357 <refsection id="databases"><title>NSS Database Types</title>
    358 <para>NSS originally used BerkeleyDB databases to store security information. 
    359 The last versions of these <emphasis>legacy</emphasis> databases are:</para>
    360 <itemizedlist>
    361 <listitem>
    362 	<para>
    363 		cert8.db for certificates
    364 	</para>
    365 </listitem>
    366 <listitem>
    367 	<para>
    368 		key3.db for keys
    369 	</para>
    370 </listitem>
    371 <listitem>
    372 	<para>
    373 		secmod.db for PKCS #11 module information
    374 	</para>
    375 </listitem>
    376 </itemizedlist>
    377 
    378 <para>BerkeleyDB has performance limitations, though, which prevent it from being easily used by multiple applications simultaneously. NSS has 
    379 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
    380 requires more flexibility to provide a truly shared security database.</para>
    381 
    382 <para>In 2009, NSS introduced a new set of databases that are SQLite databases rather than 
    383 BerkleyDB. These new databases provide more accessibility and performance:</para>
    384 <itemizedlist>
    385 <listitem>
    386 	<para>
    387 		cert9.db for certificates
    388 	</para>
    389 </listitem>
    390 <listitem>
    391 	<para>
    392 		key4.db for keys
    393 	</para>
    394 </listitem>
    395 <listitem>
    396 	<para>
    397 		pkcs11.txt, which is listing of all of the PKCS #11 modules contained in a new subdirectory in the security databases directory
    398 	</para>
    399 </listitem>
    400 </itemizedlist>
    401 
    402 <para>Because the SQLite databases are designed to be shared, these are the <emphasis>shared</emphasis> database type. The shared database type is preferred; the legacy format is included for backward compatibility.</para>
    403 
    404 <para>By default, the tools (<command>certutil</command>, <command>pk12util</command>, <command>modutil</command>) assume that the given security databases use the SQLite type
    405 Using the legacy databases must be manually specified by using the <command>dbm:</command> prefix with the given security directory. For example:</para>
    406 
    407 <programlisting># pk12util -i /tmp/cert-files/users.p12 -d dbm:/home/my/sharednssdb</programlisting>
    408 
    409 <para>To set the legacy database type as the default type for the tools, set the <envar>NSS_DEFAULT_DB_TYPE</envar> environment variable to <envar>dbm</envar>:</para>
    410 <programlisting>export NSS_DEFAULT_DB_TYPE="dbm"</programlisting>
    411 
    412 <para>This line can be set added to the <filename>~/.bashrc</filename> file to make the change permanent.</para>

    432    <para>The exporting behavior of <command>pk12util</command> has changed over time, while importing files exported with older versions of NSS is still supported.</para>
    433    <para>Until the 3.30 release, <command>pk12util</command> used the UTF-16 encoding for the PKCS #5 password-based encryption schemes, while the recommendation is to encode passwords in UTF-8 if the used encryption scheme is defined outside of the PKCS #12 standard.</para>
    434    <para>Until the 3.31 release, even when <userinput>"AES-128-CBC"</userinput> or <userinput>"AES-192-CBC"</userinput> is given from the command line, <command>pk12util</command> always used 256-bit AES as the underlying encryption scheme.</para>
    435    <para>For historical reasons, <command>pk12util</command> accepts password-based encryption schemes not listed in this document.  However, those schemes are not officially supported and may have issues in interoperability with other tools.</para>
