NAME
crlutil - List, generate, modify, or delete CRLs within the NSS security database file(s)
and list, create, modify or delete certificates entries in a particular CRL.
SYNOPSIS
crlutil [options] [[arguments]]
STATUS

Mozilla NSS bug 836477[1]
DESCRIPTION
The Certificate Revocation List (CRL) Management Tool, crlutil, is a command-line utility
that can list, generate, modify, or delete CRLs within the NSS security database file(s)
and list, create, modify or delete certificates entries in a particular CRL.
The key and certificate management process generally begins with creating keys in the key
database, then generating and managing certificates in the certificate database(see
certutil tool) and continues with certificates expiration or revocation.
This document discusses certificate revocation list management. For information on
security module database management, see Using the Security Module Database Tool. For
information on certificate and key database management, see Using the Certificate Database
Tool.
To run the Certificate Revocation List Management Tool, type the command
crlutil option [arguments]
where options and arguments are combinations of the options and arguments listed in the
following section. Each command takes one option. Each option may take zero or more
arguments. To see a usage string, issue the command without options, or with the -H
option.
OPTIONS AND ARGUMENTS
Options
Options specify an action. Option arguments modify an action. The options and arguments
for the crlutil command are defined as follows:
-D
Delete Certificate Revocation List from cert database.
-E
Erase all CRLs of specified type from the cert database
-G
Create new Certificate Revocation List (CRL).
-I
Import a CRL to the cert database
-L
List existing CRL located in cert database file.
-M
Modify existing CRL which can be located in cert db or in arbitrary file. If located
in file it should be encoded in ASN.1 encode format.
-S
Show contents of a CRL file which isn't stored in the database.
Arguments
Option arguments modify an action.
-a
Use ASCII format or allow the use of ASCII format for input and output. This
formatting follows RFC #1113.
-B
Bypass CA signature checks.
-c crl-gen-file
Specify script file that will be used to control crl generation/modification. See
crl-cript-file format below. If options -M|-G is used and -c crl-script-file is not
specified, crlutil will read script data from standard input.
-d directory
Specify the database directory containing the certificate and key database files. On
Unix the Certificate Database Tool defaults to $HOME/.netscape (that is, ~/.netscape).
On Windows NT the default is the current directory.
The NSS database files must reside in the same directory.
-f password-file
Specify a file that will automatically supply the password to include in a certificate
or to access a certificate database. This is a plain-text file containing one
password. Be sure to prevent unauthorized access to this file.
-i crl-file
Specify the file which contains the CRL to import or show.
-l algorithm-name
Specify a specific signature algorithm. List of possible algorithms: MD2 | MD4 | MD5 |
SHA1 | SHA256 | SHA384 | SHA512
-n nickname
Specify the nickname of a certificate or key to list, create, add to a database,
modify, or validate. Bracket the nickname string with quotation marks if it contains
spaces.
-o output-file
Specify the output file name for new CRL. Bracket the output-file string with
quotation marks if it contains spaces. If this argument is not used the output
destination defaults to standard output.
-P dbprefix
Specify the prefix used on the NSS security database files (for example, my_cert8.db
and my_key3.db). This option is provided as a special case. Changing the names of the
certificate and key databases is not recommended.
-t crl-type
Specify type of CRL. possible types are: 0 - SEC_KRL_TYPE, 1 - SEC_CRL_TYPE. This
option is obsolete
-u url
Specify the url.
-w pwd-string
Provide db password in command line.
-Z algorithm
Specify the hash algorithm to use for signing the CRL.
CRL GENERATION SCRIPT SYNTAX
CRL generation script file has the following syntax:
* Line with comments should have # as a first symbol of a line
* Set "this update" or "next update" CRL fields:
update=YYYYMMDDhhmmssZ nextupdate=YYYYMMDDhhmmssZ
Field "next update" is optional. Time should be in GeneralizedTime format
(YYYYMMDDhhmmssZ). For example: 20050204153000Z
* Add an extension to a CRL or a crl certificate entry:
addext extension-name critical/non-critical [arg1[arg2 ...]]
Where:
extension-name: string value of a name of known extensions. critical/non-critical: is 1
when extension is critical and 0 otherwise. arg1, arg2: specific to extension type
extension parameters
addext uses the range that was set earlier by addcert and will install an extension to
every cert entries within the range.
* Add certificate entries(s) to CRL:
addcert range date
range: two integer values separated by dash: range of certificates that will be added by
this command. dash is used as a delimiter. Only one cert will be added if there is no
delimiter. date: revocation date of a cert. Date should be represented in GeneralizedTime
format (YYYYMMDDhhmmssZ).
* Remove certificate entry(s) from CRL
rmcert range
Where:
range: two integer values separated by dash: range of certificates that will be added by
this command. dash is used as a delimiter. Only one cert will be added if there is no
delimiter.
* Change range of certificate entry(s) in CRL
range new-range
Where:
new-range: two integer values separated by dash: range of certificates that will be added
by this command. dash is used as a delimiter. Only one cert will be added if there is no
delimiter.
Implemented Extensions
The extensions defined for CRL provide methods for associating additional attributes with
CRLs of theirs entries. For more information see RFC #3280
* Add The Authority Key Identifier extension:
The authority key identifier extension provides a means of identifying the public key
corresponding to the private key used to sign a CRL.
authKeyId critical [key-id | dn cert-serial]
Where:
authKeyIdent: identifies the name of an extension critical: value of 1 of 0. Should be set
to 1 if this extension is critical or 0 otherwise. key-id: key identifier represented in
octet string. dn:: is a CA distinguished name cert-serial: authority certificate serial
number.
* Add Issuer Alternative Name extension:
The issuer alternative names extension allows additional identities to be associated with
the issuer of the CRL. Defined options include an rfc822 name (electronic mail address), a
DNS name, an IP address, and a URI.
issuerAltNames non-critical name-list
Where:
subjAltNames: identifies the name of an extension should be set to 0 since this is
non-critical extension name-list: comma separated list of names
* Add CRL Number extension:
The CRL number is a non-critical CRL extension which conveys a monotonically increasing
sequence number for a given CRL scope and CRL issuer. This extension allows users to
easily determine when a particular CRL supersedes another CRL
crlNumber non-critical number
Where:
crlNumber: identifies the name of an extension critical: should be set to 0 since this is
non-critical extension number: value of long which identifies the sequential number of a
CRL.
* Add Revocation Reason Code extension:
The reasonCode is a non-critical CRL entry extension that identifies the reason for the
certificate revocation.
reasonCode non-critical code
Where:
reasonCode: identifies the name of an extension non-critical: should be set to 0 since
this is non-critical extension code: the following codes are available:
unspecified (0), keyCompromise (1), cACompromise (2), affiliationChanged (3), superseded
(4), cessationOfOperation (5), certificateHold (6), removeFromCRL (8), privilegeWithdrawn
(9), aACompromise (10)
* Add Invalidity Date extension:
The invalidity date is a non-critical CRL entry extension that provides the date on which
it is known or suspected that the private key was compromised or that the certificate
otherwise became invalid.
invalidityDate non-critical date
Where:
crlNumber: identifies the name of an extension non-critical: should be set to 0 since this
is non-critical extension date: invalidity date of a cert. Date should be represented in
GeneralizedTime format (YYYYMMDDhhmmssZ).
USAGE
The Certificate Revocation List Management Tool's capabilities are grouped as follows,

brackets are optional, those without square brackets are required.
