   <title>Description</title>
   <para>The Security Module Database Tool, <command>modutil</command>, is a command-line utility for managing PKCS #11 module information both within <filename>secmod.db</filename> files and within hardware tokens. <command>modutil</command> can add and delete PKCS #11 modules, change passwords on security databases, set defaults, list module contents, enable or disable slots, enable or disable FIPS 140-2 compliance, and assign default providers for cryptographic operations. This tool can also create certificate, key, and module security database files.</para>

<para>The tasks associated with security module database management are part of a process that typically also involves managing key databases and certificate databases.</para>

   <title>Usage and Examples</title>

   <para><command>Creating Database Files</command></para>
   <para>Before any operations can be performed, there must be a set of security databases available. <command>modutil</command> can be used to create these files. The only required argument is the database that where the databases will be located.</para>
<programlisting>modutil -create -dbdir directory</programlisting>

<para><command>Adding a Cryptographic Module</command></para>
<para>Adding a PKCS #11 module means submitting a supporting library file, enabling its ciphers, and setting default provider status for various security mechanisms. This can be done by supplying all of the information through <command>modutil</command> directly or by running a JAR file and install script. For the most basic case, simply upload the library:</para>
<programlisting>modutil -add modulename -libfile library-file [-ciphers cipher-enable-list] [-mechanisms mechanism-list] </programlisting>
<para>For example:
<programlisting>modutil -dbdir /home/my/sharednssdb -add "Example PKCS #11 Module" -libfile "/tmp/crypto.so" -mechanisms RSA:DSA:RC2:RANDOM 

Using database directory ... 
Module "Example PKCS #11 Module" added to database.</programlisting>
       </para>


<para><command>Installing a Cryptographic Module from a JAR File</command></para>
<para>PKCS #11 modules can also be loaded using a JAR file, which contains all of the required libraries and an installation script that describes how to install the module. The JAR install script is described in more detail in <xref linkend="jar-install-file" />.</para>
<para>The JAR installation script defines the setup information for each platform that the module can be installed on. For example:</para>
<programlisting>Platforms { 
  Linux:5.4.08:x86 { 
     ModuleName { "Example PKCS #11 Module" } 
     ModuleFile { crypto.so } 
     DefaultMechanismFlags{0x0000} 
     CipherEnableFlags{0x0000} 
     Files { 
        crypto.so { 
           Path{ /tmp/crypto.so } 
        } 
        setup.sh { 
           Executable 
           Path{ /tmp/setup.sh } 
        } 
     } 
  } 
  Linux:6.0.0:x86 { 
     EquivalentPlatform { Linux:5.4.08:x86 } 
  } 
} </programlisting>
<para>Both the install script and the required libraries must be bundled in a JAR file, which is specified with the <option>-jar</option> argument.</para>

<programlisting>modutil -dbdir /home/mt"jar-install-filey/sharednssdb -jar install.jar -installdir /home/my/sharednssdb

<para><command>Setting a Default Provider for Security Mechanisms</command></para>
<para>Multiple security modules may provide support for the same security mechanisms. It is possible to set a specific security module as the default provider for a specific security mechanism (or, conversely, to prohibit a provider from supplying those mechanisms).</para>
<programlisting>modutil -default modulename -mechanisms mechanism-list </programlisting>
<para>To set a module as the default provider for mechanisms, use the <option>-default</option> command with a colon-separated list of mechanisms. The available mechanisms depend on the module; NSS supplies almost all common mechanisms. For example:</para>
<programlisting>modutil -default "NSS Internal PKCS #11 Module" -dbdir -mechanisms RSA:DSA:RC2 

Using database directory c:\databases...

Successfully changed defaults.</programlisting>

   <para>Clearing the default provider has the same format:</para>

<para><command>Enabling and Disabling Modules and Slots</command></para>
<para>Modules, and specific slots on modules, can be selectively enabled or disabled using <command>modutil</command>. Both commands have the same format:</para>
<programlisting>modutil -enable|-disable modulename [-slot slotname] </programlisting>

   <para>For example:</para>
<programlisting>modutil -enable "NSS Internal PKCS #11 Module" -slot "NSS Internal Cryptographic Services                            " -dbdir .

Slot "NSS Internal Cryptographic Services                            " enabled.</programlisting>
<para>Be sure that the appropriate amount of trailing whitespace is after the slot name. Some slot names have a significant amount of whitespace that must be included, or the operation will fail.</para>

<para><command>Enabling and Verifying FIPS Compliance</command></para>
<para>The NSS modules can have FIPS 140-2 compliance enabled or disabled using <command>modutil</command> with the <option>-fips</option> option. For example:</para>
<programlisting>modutil -fips true -dbdir /home/my/sharednssdb/

FIPS mode enabled.</programlisting>
<para>To verify that status of FIPS mode, run the <option>-chkfips</option> command with either a true or false flag (it doesn't matter which). The tool returns the current FIPS setting.</para>
<programlisting>modutil -chkfips false -dbdir /home/my/sharednssdb/

FIPS mode enabled.</programlisting>

<para><command>Changing the Password on a Token</command></para>

   <para>Initializing or changing a token's password:</para>

 <refsection id="jar-install-file"><title>JAR Installation File Format</title>
    <para>When a JAR file is run by a server, by <command>modutil</command>, or by any program that does not interpret JavaScript, a special information file must be included to install the libraries. There are several things to keep in mind with this file:</para>

<para>Quotes and backslashes must be escaped with a backslash. A complex string must not include newlines or carriage returns.Outside of complex strings, all white space (for example, spaces, tabs, and carriage returns) is considered equal and is used only to delimit tokens.</para>

<para><command>Keys</command></para>
<para>The Java install file uses keys to define the platform and module information.</para>
<para><command>ForwardCompatible</command> gives a list of platforms that are forward compatible. If the current platform cannot be found in the list of supported platforms, then the <command>ForwardCompatible</command> list is checked for any platforms that have the same OS and architecture in an earlier version. If one is found, its attributes are used for the current platform. </para>
<para><command>Platforms</command> (required) Gives a list of platforms. Each entry in the list is itself a key-value pair: the key is the name of the platform and the value list contains various attributes of the platform. The platform string is in the format <emphasis>system name:OS release:architecture</emphasis>. The installer obtains these values from NSPR. OS release is an empty string on non-Unix operating systems. NSPR supports these platforms:</para>

</programlisting>
<para>The module information is defined independently for each platform in the <command>ModuleName</command>, <command>ModuleFile</command>, and <command>Files</command> attributes. These attributes must be given unless an <command>EquivalentPlatform</command> attribute is specified. </para>

<para><command>Per-Platform Keys</command></para>
<para>Per-platform keys have meaning only within the value list of an entry in the <command>Platforms</command> list.</para>
<para><command>ModuleName</command> (required) gives the common name for the module. This name is used to reference the module by servers and by the <command>modutil</command> tool. </para>
<para><command>ModuleFile</command> (required) names the PKCS #11 module file for this platform. The name is given as the relative path of the file within the JAR archive. </para>
<para><command>Files</command> (required) lists the files that need to be installed for this module. Each entry in the file list is a key-value pair. The key is the path of the file in the JAR archive, and the value list contains attributes of the file. At least <command>RelativePath</command> or <command>AbsolutePath</command> must be specified for each file.</para>
<para><command>DefaultMechanismFlags</command> specifies mechanisms for which this module is the default provider; this is equivalent to the <option>-mechanism</option> option with the <option>-add</option> command. This key-value pair is a bitstring specified in hexadecimal (0x) format. It is constructed as a bitwise OR. If the DefaultMechanismFlags entry is omitted, the value defaults to 0x0.</para>

<programlisting>RSA:                   0x00000001

<para><command>CipherEnableFlags</command> specifies ciphers that this module provides that NSS does not provide (so that the module enables those ciphers for NSS). This is equivalent to the <option>-cipher</option> argument with the <option>-add</option> command. This key is a bitstring specified in hexadecimal (0x) format. It is constructed as a bitwise OR. If the <command>CipherEnableFlags</command> entry is omitted, the value defaults to 0x0.</para>

<para><command>EquivalentPlatform</command> specifies that the attributes of the named platform should also be used for the current platform. This makes it easier when more than one platform uses the same settings.</para>

<para><command>Per-File Keys</command></para>
<para>Some keys have meaning only within the value list of an entry in a <command>Files</command> list.</para>
<para>Each file requires a path key the identifies where the file is. Either <command>RelativePath</command> or <command>AbsolutePath</command> must be specified. If both are specified, the relative path is tried first, and the absolute path is used only if no relative root directory is provided by the installer program.</para>
<para><command>RelativePath</command> specifies the destination directory of the file, relative to some directory decided at install time. Two variables can be used in the relative path: <command>%root%</command> and <command>%temp%</command>. <command>%root%</command> is replaced at run time with the directory relative to which files should be installed; for example, it may be the server's root directory. The <command>%temp%</command> directory is created at the beginning of the installation and destroyed at the end. The purpose of <command>%temp%</command> is to hold executable files (such as setup programs) or files that are used by these programs. Files destined for the temporary directory are guaranteed to be in place before any executable file is run; they are not deleted until all executable files have finished.</para>
<para><command>AbsolutePath</command> specifies the destination directory of the file as an absolute path. </para>
<para><command>Executable</command> specifies that the file is to be executed during the course of the installation. Typically, this string is used for a setup program provided by a module vendor, such as a self-extracting setup executable. More than one file can be specified as executable, in which case the files are run in the order in which they are specified in the script file.</para>
<para><command>FilePermissions</command> sets permissions on any referenced files in a string of octal digits, according to the standard Unix format. This string is a bitwise OR.</para>

<programlisting>
user read:                0400
user write:               0200
user execute:             0100
group read:               0040
group write:              0020
group execute:            0010
other read:               0004
other write:              0002
other execute:            0001
</programlisting>

<para>Some platforms may not understand these permissions. They are applied only insofar as they make sense for the current platform. If this attribute is omitted, a default of 777 is assumed.</para>

<refsection id="databases"><title>NSS Database Types</title>
<para>NSS originally used BerkeleyDB databases to store security information. 
The last versions of these <emphasis>legacy</emphasis> databases are:</para>
<itemizedlist>
<listitem>
	<para>
		cert8.db for certificates
	</para>
</listitem>
<listitem>
	<para>
		key3.db for keys
	</para>
</listitem>
<listitem>
	<para>
		secmod.db for PKCS #11 module information
	</para>
</listitem>
</itemizedlist>

<para>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.</para>

<para>In 2009, NSS introduced a new set of databases that are SQLite databases rather than 
BerkleyDB. These new databases provide more accessibility and performance:</para>
<itemizedlist>
<listitem>
	<para>
		cert9.db for certificates
	</para>
</listitem>
<listitem>
	<para>
		key4.db for keys
	</para>
</listitem>
<listitem>
	<para>
		pkcs11.txt, which is listing of all of the PKCS #11 modules contained in a new subdirectory in the security databases directory
	</para>
</listitem>
</itemizedlist>

<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>

<para>By default, the tools (<command>certutil</command>, <command>pk12util</command>, <command>modutil</command>) assume that the given security databases use the SQLite type.
Using the legacy databases must be manually specified by using the <command>dbm:</command> prefix with the given security directory. For example:</para>

<programlisting>modutil -create -dbdir dbm:/home/my/sharednssdb</programlisting>

<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>
<programlisting>export NSS_DEFAULT_DB_TYPE="dbm"</programlisting>

<para>This line can be added to the <filename>~/.bashrc</filename> file to make the change permanent for the user.</para>
