.SH "NAME"
modutil \- Manage PKCS #11 module information within the security module database\&.
.SH "SYNOPSIS"
.HP \w'\fBmodutil\fR\ 'u
\fBmodutil\fR [\fIoptions\fR] [[\fIarguments\fR]]
.SH "STATUS"
.PP
This documentation is still work in progress\&. Please contribute to the initial review in
\m[blue]\fBMozilla NSS bug 836477\fR\m[]\&\s-2\u[1]\d\s+2
.SH "DESCRIPTION"
.PP
The Security Module Database Tool,
\fBmodutil\fR, is a command\-line utility for managing PKCS #11 module information both within
secmod\&.db
files and within hardware tokens\&.
\fBmodutil\fR
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\&.
.PP
The tasks associated with security module database management are part of a process that typically also involves managing key databases and certificate databases\&.
.SH "OPTIONS"
.PP
Running
\fBmodutil\fR
always requires one (and only one) option to specify the type of module operation\&. Each option may take arguments, anywhere from none to multiple arguments\&.
.PP
\fBOptions\fR
.PP
\-add modulename
.RS 4
Add the named PKCS #11 module to the database\&. Use this option with the
\fB\-libfile\fR,
\fB\-ciphers\fR, and
\fB\-mechanisms\fR
arguments\&.
.RE
.PP
\-changepw tokenname
.RS 4
Change the password on the named token\&. If the token has not been initialized, this option initializes the password\&. Use this option with the
\fB\-pwfile\fR
and
\fB\-newpwfile\fR
arguments\&. A
\fIpassword\fR
is equivalent to a personal identification number (PIN)\&.
.RE
.PP
\-chkfips
.RS 4
Verify whether the module is in the given FIPS mode\&.
\fBtrue\fR
means to verify that the module is in FIPS mode, while
\fBfalse\fR
means to verify that the module is not in FIPS mode\&.
.RE
.PP
\-create
.RS 4
Create new certificate, key, and module databases\&. Use the
\fB\-dbdir\fR
directory argument to specify a directory\&. If any of these databases already exist in a specified directory,
\fBmodutil\fR
returns an error message\&.
.RE
.PP
\-default modulename
.RS 4
Specify the security mechanisms for which the named module will be a default provider\&. The security mechanisms are specified with the
\fB\-mechanisms\fR
argument\&.
.RE
.PP
\-delete modulename
.RS 4
Delete the named module\&. The default NSS PKCS #11 module cannot be deleted\&.
.RE
.PP
\-disable modulename
.RS 4
Disable all slots on the named module\&. Use the
\fB\-slot\fR
argument to disable a specific slot\&.
.sp
The internal NSS PKCS #11 module cannot be disabled\&.
.RE
.PP
\-enable modulename
.RS 4
Enable all slots on the named module\&. Use the
\fB\-slot\fR
argument to enable a specific slot\&.
.RE
.PP
\-fips [true | false]
.RS 4
Enable (true) or disable (false) FIPS 140\-2 compliance for the default NSS module\&.
.RE
.PP
\-force
.RS 4
Disable
\fBmodutil\fR\*(Aqs interactive prompts so it can be run from a script\&. Use this option only after manually testing each planned operation to check for warnings and to ensure that bypassing the prompts will cause no security lapses or loss of database integrity\&.
.RE
.PP
\-jar JAR\-file
.RS 4
Add a new PKCS #11 module to the database using the named JAR file\&. Use this command with the
\fB\-installdir\fR
and
\fB\-tempdir\fR
arguments\&. The JAR file uses the NSS PKCS #11 JAR format to identify all the files to be installed, the module\*(Aqs name, the mechanism flags, and the cipher flags, as well as any files to be installed on the target machine, including the PKCS #11 module library file and other files such as documentation\&. This is covered in the JAR installation file section in the man page, which details the special script needed to perform an installation through a server or with
\fBmodutil\fR\&.
.RE
.PP
\-list [modulename]
.RS 4
Display basic information about the contents of the
secmod\&.db
file\&. Specifying a
\fImodulename\fR
displays detailed information about a particular module and its slots and tokens\&.
.RE
.PP
\-rawadd
.RS 4
Add the module spec string to the
secmod\&.db
database\&.
.RE
.PP
\-rawlist
.RS 4
Display the module specs for a specified module or for all loadable modules\&.
.RE
.PP
\-undefault modulename
.RS 4
Specify the security mechanisms for which the named module will not be a default provider\&. The security mechanisms are specified with the
\fB\-mechanisms\fR
argument\&.
.RE
.PP
\fBArguments\fR
.PP
MODULE
.RS 4
Give the security module to access\&.
.RE
.PP
MODULESPEC
.RS 4

\fBFiles\fR

\fBRelativePath\fR

Each file requires a path key the identifies where the file is\&. Either
\fBRelativePath\fR
or
\fBAbsolutePath\fR
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\&.
.PP
\fBRelativePath\fR
specifies the destination directory of the file, relative to some directory decided at install time\&. Two variables can be used in the relative path:
\fB%root%\fR
and
\fB%temp%\fR\&.
\fB%root%\fR
is replaced at run time with the directory relative to which files should be installed; for example, it may be the server\*(Aqs root directory\&. The
\fB%temp%\fR
directory is created at the beginning of the installation and destroyed at the end\&. The purpose of
\fB%temp%\fR
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\&.
.PP
\fBAbsolutePath\fR
specifies the destination directory of the file as an absolute path\&.
.PP
\fBExecutable\fR
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\&.

.SH "NSS DATABASE TYPES"
.PP
NSS originally used BerkeleyDB databases to store security information\&. The last versions of these
\fIlegacy\fR
databases are:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
secmod\&.db for PKCS #11 module information
.RE
.PP
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\&.
.PP
In 2009, NSS introduced a new set of databases that are SQLite databases rather than BerkleyDB\&. These new databases provide more accessibility and performance:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

.sp
.RS 4
.ie n \{\

.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
pkcs11\&.txt, which is listing of all of the PKCS #11 modules contained in a new subdirectory in the security databases directory
.RE
.PP
Because the SQLite databases are designed to be shared, these are the
\fIshared\fR
database type\&. The shared database type is preferred; the legacy format is included for backward compatibility\&.
.PP
By default, the tools (\fBcertutil\fR,
\fBpk12util\fR,
\fBmodutil\fR) assume that the given security databases follow the more common legacy type\&. Using the SQLite databases must be manually specified by using the
\fBsql:\fR
prefix with the given security directory\&. For example:
.sp
.if n \{\
.RS 4
.\}
.nf
modutil \-create \-dbdir sql:/home/my/sharednssdb
.fi
.if n \{\
.RE
.\}
.PP
To set the shared database type as the default type for the tools, set the
\fBNSS_DEFAULT_DB_TYPE\fR
environment variable to
\fBsql\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
export NSS_DEFAULT_DB_TYPE="sql"
.fi
.if n \{\
.RE
.\}
.PP
This line can be added to the
~/\&.bashrc
file to make the change permanent for the user\&.
.PP
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:
