security database file(s) and list, create, modify or delete
certificates entries in a particular CRL.
SYNOPSIS
crlutil [options] [[arguments]]
STATUS
This documentation is still work in progress. Please contribute to the
initial review in 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, using these combinations of options and arguments.
Options and arguments in square brackets are optional, those without
square brackets are required.
See "Implemented extensions" for more information regarding extensions
and their parameters.

crlutil -G|-M -c crl-gen-file -n nickname [-i crl] [-u url] [-d keydir] [-P dbprefix] [-l alg] [-a] [-B]
* Listing all CRls or a named CRL:
crlutil -L [-n crl-name] [-d krydir]
* Deleting CRL from db:
crlutil -D -n nickname [-d keydir] [-P dbprefix]
* Erasing CRLs from db:
crlutil -E [-d keydir] [-P dbprefix]
* Deleting CRL from db:
crlutil -D -n nickname [-d keydir] [-P dbprefix]
* Erasing CRLs from db:
crlutil -E [-d keydir] [-P dbprefix]
