=head1 DESCRIPTION
|
|
|
|
|
|
|
|
The B<req> command primarily creates and processes certificate requests
|
|
|
|
in PKCS#10 format. It can additionally create self signed certificates
|
|
|
|
for use as root CAs for example.
|
|
|
|
|
|
|
|
=head1 COMMAND OPTIONS
|
|
|
|
|
|
|
|
=over 4
|
|
|
|
|
|
|
|
=item B<-inform DER|PEM>
|
|
|
|
|
|
|
|
This specifies the input format. The B<DER> option uses an ASN1 DER encoded
|
|
|
|
form compatible with the PKCS#10. The B<PEM> form is the default format: it
|
|
|
|
consists of the B<DER> format base64 encoded with additional header and
|
|
|
|
footer lines.
|
|
|
|
|
|
|
|
=item B<-outform DER|PEM>
|
|
|
|
|
|
|
|
This specifies the output format, the options have the same meaning as the
|
|
|
|
B<-inform> option.
|
|
|
|
|
|
|
|
=item B<-in filename>
|
|
|
|
|
|
|
|
This specifies the input filename to read a request from or standard input
|
|
|
|
if this option is not specified. A request is only read if the creation
|
|
|
|
options (B<-new> and B<-newkey>) are not specified.

1999-11-10 10:52:17 +08:00
|
|
|
=item B<-text>
|
|
|
|
|
|
|
|
prints out the certificate request in text form.
|
|
|
|
|
2009-04-15 23:27:03 +08:00
|
|
|
=item B<-subject>
|
|
|
|
|
|
|
|
prints out the request subject (or certificate subject if B<-x509> is
|
|
|
|
specified)
|
|
|
|
|
2001-12-02 07:03:30 +08:00
|
|
|
=item B<-pubkey>
|
|
|
|
|
|
|
|
outputs the public key.
|
|
|
|
|
1999-11-10 10:52:17 +08:00
|
|
|
=item B<-noout>
|
|
|
|
|
|
|
|
this option prevents output of the encoded version of the request.
|
|
|
|
|
|
|
|
=item B<-modulus>
|
|
|
|
|
|
|
|
this option prints out the value of the modulus of the public key
|
|
|
|
contained in the request.
|
|
|
|
|
|
|
|
=item B<-verify>
|
|
|
|
|
|
|
|
verifies the signature on the request.
|
|
|
|
|
|
|
|
=item B<-new>
|
|
|
|
|
|
|
|
this option generates a new certificate request. It will prompt
|
|
|
|
the user for the relevant field values. The actual fields
|
|
|
|
prompted for and their maximum and minimum sizes are specified
|
|
|
|
in the configuration file and any requested extensions.
|
|
|
|
|
|
|
|
If the B<-key> option is not used it will generate a new RSA private
|
|
|
|
key using information specified in the configuration file.
|
|
|
|
|
2009-04-15 23:27:03 +08:00
|
|
|
=item B<-subj arg>
|
|
|
|
|
|
|
|
Replaces subject field of input request with specified data and outputs
|
|
|
|
modified request. The arg must be formatted as
|
|
|
|
I</type0=value0/type1=value1/type2=...>,
|
|
|
|
characters may be escaped by \ (backslash), no spaces are skipped.
|
|
|
|
|
2000-06-22 17:19:59 +08:00
|
|
|
=item B<-rand file(s)>
|
|
|
|
|
|
|
|
a file or files containing random data used to seed the random number
|
|
|
|
generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
|
|
|
|
Multiple files can be specified separated by a OS-dependent character.
|
|
|
|
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
|
|
|
|
all others.
|
|
|
|
|
1999-11-10 10:52:17 +08:00
|
|
|
=item B<-newkey arg>
|
|
|
|
|
|
|
|
this option creates a new certificate request and a new private
|
2006-07-08 08:24:47 +08:00
|
|
|
key. The argument takes one of several forms. B<rsa:nbits>, where
|
1999-11-10 10:52:17 +08:00
|
|
|
B<nbits> is the number of bits, generates an RSA key B<nbits>
|
2009-04-15 23:27:03 +08:00
|
|
|
in size. If B<nbits> is omitted, i.e. B<-newkey rsa> specified,
|
|
|
|
the default key size, specified in the configuration file is used.
|
|
|
|
|
|
|
|
All other algorithms support the B<-newkey alg:file> form, where file may be
|
|
|
|
an algorithm parameter file, created by the B<genpkey -genparam> command
|
|
|
|
or and X.509 certificate for a key with approriate algorithm.
|
|
|
|
|
|
|
|
B<param:file> generates a key using the parameter file or certificate B<file>,
|
|
|
|
the algorithm is determined by the parameters. B<algname:file> use algorithm
|
|
|
|
B<algname> and parameter file B<file>: the two algorithms must match or an
|
|
|
|
error occurs. B<algname> just uses algorithm B<algname>, and parameters,
|
2013-06-13 07:22:32 +08:00
|
|
|
if necessary should be specified via B<-pkeyopt> parameter.
|
2009-04-15 23:27:03 +08:00
|
|
|
|
|
|
|
B<dsa:filename> generates a DSA key using the parameters
|
|
|
|
in the file B<filename>. B<ec:filename> generates EC key (usable both with
|
|
|
|
ECDSA or ECDH algorithms), B<gost2001:filename> generates GOST R
|
|
|
|
34.10-2001 key (requires B<ccgost> engine configured in the configuration
|
|
|
|
file). If just B<gost2001> is specified a parameter set should be
|
|
|
|
specified by B<-pkeyopt paramset:X>
|
|
|
|
|
2006-07-08 08:24:47 +08:00
|
|
|
|
|
|
|
=item B<-pkeyopt opt:value>
|
|
|
|
|
|
|
|
set the public key algorithm option B<opt> to B<value>. The precise set of
|
|
|
|
options supported depends on the public key algorithm used and its
|
|
|
|
implementation. See B<KEY GENERATION OPTIONS> in the B<genpkey> manual page
|
|
|
|
for more details.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
=item B<-key filename>
|
|
|
|
|
|
|
|
This specifies the file to read the private key from. It also
|
|
|
|
accepts PKCS#8 format private keys for PEM format files.
|
|
|
|
|
|
|
|
=item B<-keyform PEM|DER>
|
|
|
|
|
|
|
|
the format of the private key file specified in the B<-key>
|
|
|
|
argument. PEM is the default.
|
|
|
|
|
|
|
|
=item B<-keyout filename>
|
|
|
|
|
|
|
|
this gives the filename to write the newly created private key to.
|
|
|
|
If this option is not specified then the filename present in the
|
|
|
|
configuration file is used.
|
|
|
|
|
|
|
|
=item B<-nodes>
|
|
|
|
|
|
|
|
if this option is specified then if a private key is created it
|
|
|
|
will not be encrypted.
|
|
|
|
|
2009-04-15 23:27:03 +08:00
|
|
|
=item B<-[digest]>
|
|
|
|
|
|
|
|
this specifies the message digest to sign the request with (such as
|
|
|
|
B<-md5>, B<-sha1>). This overrides the digest algorithm specified in
|
|
|
|
the configuration file.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
2009-04-15 23:27:03 +08:00
|
|
|
Some public key algorithms may override this choice. For instance, DSA
|
|
|
|
signatures always use SHA1, GOST R 34.10 signatures always use
|
|
|
|
GOST R 34.11-94 (B<-md_gost94>).
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
=item B<-config filename>
|
|
|
|
|
|
|
|
this allows an alternative configuration file to be specified,
|
|
|
|
this overrides the compile time filename or any specified in
|
|
|
|
the B<OPENSSL_CONF> environment variable.
|
|
|
|
|
2001-03-05 19:09:43 +08:00
|
|
|
=item B<-subj arg>
|
|
|
|
|
|
|
|
sets subject name for new request or supersedes the subject name
|
|
|
|
when processing a request.
|
2002-04-30 20:08:18 +08:00
|
|
|
The arg must be formatted as I</type0=value0/type1=value1/type2=...>,
|
|
|
|
characters may be escaped by \ (backslash), no spaces are skipped.
|
2001-03-05 19:09:43 +08:00
|
|
|
|
2005-07-15 17:49:03 +08:00
|
|
|
=item B<-multivalue-rdn>
|
|
|
|
|
|
|
|
this option causes the -subj argument to be interpreted with full
|
|
|
|
support for multivalued RDNs. Example:
|
|
|
|
|
|
|
|
I</DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe>
|
|
|
|
|
|
|
|
If -multi-rdn is not used then the UID value is I<123456+CN=John Doe>.
|
|
|
|
|
1999-11-10 10:52:17 +08:00
|
|
|
=item B<-x509>
|
|
|
|
|
|
|
|
this option outputs a self signed certificate instead of a certificate
|
|
|
|
request. This is typically used to generate a test certificate or
|
|
|
|
a self signed root CA. The extensions added to the certificate
|
2001-03-09 21:57:14 +08:00
|
|
|
(if any) are specified in the configuration file. Unless specified
|
2014-09-01 06:22:09 +08:00
|
|
|
using the B<set_serial> option, a large random number will be used for
|
|
|
|
the serial number.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
=item B<-days n>
|
|
|
|
|
|
|
|
when the B<-x509> option is being used this specifies the number of
|
|
|
|
days to certify the certificate for. The default is 30 days.
|
|
|
|
|
2001-03-09 21:57:14 +08:00
|
|
|
=item B<-set_serial n>
|
|
|
|
|
2001-09-07 14:13:40 +08:00
|
|
|
serial number to use when outputting a self signed certificate. This
|
2001-03-09 21:57:14 +08:00
|
|
|
may be specified as a decimal value or a hex value if preceded by B<0x>.
|
|
|
|
It is possible to use negative serial numbers but this is not recommended.

|
|
|
=item B<-reqexts section>
|
|
|
|
|
|
|
|
these options specify alternative sections to include certificate
|
|
|
|
extensions (if the B<-x509> option is present) or certificate
|
|
|
|
request extensions. This allows several different sections to
|
|
|
|
be used in the same configuration file to specify requests for
|
|
|
|
a variety of purposes.
|
|
|
|
|
2001-10-26 20:40:38 +08:00
|
|
|
=item B<-utf8>
|
|
|
|
|
|
|
|
this option causes field values to be interpreted as UTF8 strings, by
|
|
|
|
default they are interpreted as ASCII. This means that the field
|
|
|
|
values, whether prompted from a terminal or obtained from a
|
|
|
|
configuration file, must be valid UTF8 strings.

|
option which determines how the subject or issuer names are displayed. The
|
|
|
|
B<option> argument can be a single option or multiple options separated by
|
|
|
|
commas. Alternatively the B<-nameopt> switch may be used more than once to
|
|
|
|
set multiple options. See the L<x509(1)|x509(1)> manual page for details.

|
accept requests containing no attributes in an invalid form: this
|
|
|
|
option produces this invalid format.
|
|
|
|
|
|
|
|
More precisely the B<Attributes> in a PKCS#10 certificate request
|
|
|
|
are defined as a B<SET OF Attribute>. They are B<not OPTIONAL> so
|
|
|
|
if no attributes are present then they should be encoded as an
|
|
|
|
empty B<SET OF>. The invalid form does not include the empty
|
|
|
|
B<SET OF> whereas the correct form does.
|
|
|
|
|
|
|
|
It should be noted that very few CAs still require the use of this option.

|
The configuration options are specified in the B<req> section of
|
1999-11-10 10:52:17 +08:00
|
|
|
the configuration file. As with all configuration files if no
|
|
|
|
value is specified in the specific section (i.e. B<req>) then
|
|
|
|
the initial unnamed or B<default> section is searched too.
|
|
|
|
|
|
|
|
The options available are described in detail below.

the output private key file (if one will be created). The
|
2000-02-17 07:16:01 +08:00

=item B<default_bits>
|
|
|
|
|
|
|
|
This specifies the default key size in bits. If not specified then
|
|
|
|
512 is used. It is used if the B<-new> option is used. It can be
|
2000-01-07 09:39:59 +08:00
|
|
|
overridden by using the B<-newkey> option.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
=item B<default_keyfile>
|
|
|
|
|
|
|
|
This is the default filename to write a private key to. If not
|
|
|
|
specified the key is written to standard output. This can be
|
2000-01-07 09:39:59 +08:00
|
|
|
overridden by the B<-keyout> option.

|
|
|
|
|
|
|
=item B<oid_file>
|
|
|
|
|
|
|
|
This specifies a file containing additional B<OBJECT IDENTIFIERS>.
|
|
|
|
Each line of the file should consist of the numerical form of the
|
|
|
|
object identifier followed by white space then the short name followed
|
|
|
|
by white space and finally the long name.
|
|
|
|
|
|
|
|
=item B<oid_section>
|
|
|
|
|
|
|
|
This specifies a section in the configuration file containing extra
|
1999-11-12 09:04:39 +08:00
|
|
|
object identifiers. Each line should consist of the short name of the
|
|
|
|
object identifier followed by B<=> and the numerical form. The short
|
1999-11-10 10:52:17 +08:00
|
|
|
and long names are the same when this option is used.
|
|
|
|
|
|
|
|
=item B<RANDFILE>
|
|
|
|
|
|
|
|
This specifies a filename in which random number seed information is
|
2000-02-25 01:18:51 +08:00
|
|
|
placed and read from, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
|
|
|
|
It is used for private key generation.

=item B<encrypt_key>
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
If this is set to B<no> then if a private key is generated it is
|
|
|
|
B<not> encrypted. This is equivalent to the B<-nodes> command line
|
2000-01-20 09:37:17 +08:00
|
|
|
option. For compatibility B<encrypt_rsa_key> is an equivalent option.

|
|
|
|
|
|
|
=item B<default_md>
|
|
|
|
|
|
|
|
This option specifies the digest algorithm to use. Possible values
|
|
|
|
include B<md5 sha1 mdc2>. If not present then MD5 is used. This
|
|
|
|
option can be overridden on the command line.

|
|
|
|
2000-01-06 09:26:48 +08:00
|
|
|
This option masks out the use of certain string types in certain
|
|
|
|
fields. Most users will not need to change this option.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
It can be set to several values B<default> which is also the default
|
|
|
|
option uses PrintableStrings, T61Strings and BMPStrings if the
|
|
|
|
B<pkix> value is used then only PrintableStrings and BMPStrings will
|
|
|
|
be used. This follows the PKIX recommendation in RFC2459. If the
|
|
|
|
B<utf8only> option is used then only UTF8Strings will be used: this
|
2000-01-06 09:26:48 +08:00
|
|
|
is the PKIX recommendation in RFC2459 after 2003. Finally the B<nombstr>
|
1999-11-10 10:52:17 +08:00
|
|
|
option just uses PrintableStrings and T61Strings: certain software has
|
2000-01-06 09:26:48 +08:00
|
|
|
problems with BMPStrings and UTF8Strings: in particular Netscape.

=item B<attributes>
|

this specifies the section containing any request attributes: its format
|
2000-01-20 09:37:17 +08:00
|
|
|
is the same as B<distinguished_name>. Typically these may contain the
|
|
|
|
challengePassword or unstructuredName types. They are currently ignored
|
|
|
|
by OpenSSL's request signing utilities but some CAs might want them.

=item B<distinguished_name>
|
|
|
|

This specifies the section containing the distinguished name fields to

2000-01-20 09:37:17 +08:00
|
|
|
prompt for when generating a certificate or certificate request. The format

is described in the next section.

=head1 DISTINGUISHED NAME AND ATTRIBUTE SECTION FORMAT
|
|
|
|
|
|
|
|
There are two separate formats for the distinguished name and attribute
|
|
|
|
sections. If the B<prompt> option is set to B<no> then these sections
|
|
|
|
just consist of field names and values: for example,
|
1999-11-10 10:52:17 +08:00
|
|
|
|
2000-01-20 09:37:17 +08:00
|
|
|
CN=My Name
|
|
|
|
OU=My Organization
|
2000-02-04 07:23:24 +08:00
|
|
|
emailAddress=someone@somewhere.org
|
2000-01-20 09:37:17 +08:00
|
|
|
|
|
|
|
This allows external programs (e.g. GUI based) to generate a template file
|
|
|
|
with all the field names and values and just pass it to B<req>. An example
|
2000-02-18 08:54:21 +08:00
|
|
|
of this kind of configuration file is contained in the B<EXAMPLES> section.
|
2000-01-20 09:37:17 +08:00
|
|
|
|
2000-02-18 08:54:21 +08:00
|
|
|
Alternatively if the B<prompt> option is absent or not set to B<no> then the
|
2000-01-20 09:37:17 +08:00
|
|
|
file contains field prompting information. It consists of lines of the form:
|
|
|
|
|
|
|
|
fieldName="prompt"
|
|
|
|
fieldName_default="default field value"
|
|
|
|
fieldName_min= 2
|
|
|
|
fieldName_max= 4
|
1999-11-10 10:52:17 +08:00
|
|
|
|
2000-01-02 00:42:49 +08:00
|
|
|
"fieldName" is the field name being used, for example commonName (or CN).
|
2000-01-07 09:39:59 +08:00
|
|
|
The "prompt" string is used to ask the user to enter the relevant
|
1999-11-10 10:52:17 +08:00
|
|
|
details. If the user enters nothing then the default value is used if no
|
|
|
|
default value is present then the field is omitted. A field can
|
|
|
|
still be omitted if a default value is present if the user just
|
|
|
|
enters the '.' character.
|
|
|
|
|
|
|
|
The number of characters entered must be between the fieldName_min and
|
|
|
|
fieldName_max limits: there may be additional restrictions based
|
|
|
|
on the field being used (for example countryName can only ever be
|
|
|
|
two characters long and must fit in a PrintableString).
|
|
|
|
|
|
|
|
Some fields (such as organizationName) can be used more than once
|
|
|
|
in a DN. This presents a problem because configuration files will
|
2000-01-20 09:37:17 +08:00
|
|
|
not recognize the same name occurring twice. To avoid this problem
|
2000-02-18 08:54:21 +08:00
|
|
|
if the fieldName contains some characters followed by a full stop
|
1999-11-10 10:52:17 +08:00
|
|
|
they will be ignored. So for example a second organizationName can
|
|
|
|
be input by calling it "1.organizationName".
|
|
|
|
|
|
|
|
The actual permitted field names are any object identifier short or
|
|
|
|
long names. These are compiled into OpenSSL and include the usual
|
|
|
|
values such as commonName, countryName, localityName, organizationName,
|
2003-01-10 16:54:01 +08:00
|
|
|
organizationUnitName, stateOrProvinceName. Additionally emailAddress
|
2000-02-18 08:54:21 +08:00
|
|
|
is include as well as name, surname, givenName initials and dnQualifier.
|
1999-11-10 10:52:17 +08:00
|
|
|
|
|
|
|
Additional object identifiers can be defined with the B<oid_file> or
|
|
|
|
B<oid_section> options in the configuration file. Any additional fields
|
|
|
|
will be treated as though they were a DirectoryString.

The certificate requests generated by B<Xenroll> with MSIE have extensions
|
|
|
|
added. It includes the B<keyUsage> extension which determines the type of
|
|
|
|
key (signature only or general purpose) and any additional OIDs entered
|
|
|
|
by the script in an extendedKeyUsage extension.

|
|
|
|
|
|
|
|
The following messages are frequently asked about:
|
|
|
|
|
|
|
|
Using configuration from /some/path/openssl.cnf
|
|
|
|
Unable to load config info
|
|
|
|
|
|
|
|
This is followed some time later by...
|
|
|
|
|
|
|
|
unable to find 'distinguished_name' in config
|
|
|
|
problems making Certificate Request
|
|
|
|
|
|
|
|
The first error message is the clue: it can't find the configuration
|
|
|
|
file! Certain operations (like examining a certificate request) don't
|
|
|
|
need a configuration file so its use isn't enforced. Generation of
|
2000-01-07 09:39:59 +08:00
|
|
|
certificates or requests however does need a configuration file. This
|
1999-11-10 10:52:17 +08:00
|
|
|
could be regarded as a bug.
|
|
|
|
|
|
|
|
Another puzzling message is this:
|
|
|
|
|
|
|
|
Attributes:
|
|
|
|
a0:00
|
|
|
|
|
|
|
|
this is displayed when no attributes are present and the request includes
|
|
|
|
the correct empty B<SET OF> structure (the DER encoding of which is 0xa0
|
|
|
|
0x00). If you just see:
|
|
|
|
|
|
|
|
Attributes:
|
|
|
|
|
|
|
|
then the B<SET OF> is missing and the encoding is technically invalid (but
|
|
|
|
it is tolerated). See the description of the command line option B<-asn1-kludge>
|
|
|
|
for more information.

|
=head1 ENVIRONMENT VARIABLES
|
|
|
|
|
|
|
|
The variable B<OPENSSL_CONF> if defined allows an alternative configuration
|
|
|
|
file location to be specified, it will be overridden by the B<-config> command
|
2000-01-07 09:39:59 +08:00
|
|
|
line switch if it is present. For compatibility reasons the B<SSLEAY_CONF>
|
1999-11-10 10:52:17 +08:00
|
|
|
environment variable serves the same purpose but its use is discouraged.

=head1 BUGS
|
|
|
|
|
2000-01-07 09:39:59 +08:00
|
|
|
OpenSSL's handling of T61Strings (aka TeletexStrings) is broken: it effectively
|
|
|
|
treats them as ISO-8859-1 (Latin 1), Netscape and MSIE have similar behaviour.
|
1999-11-10 10:52:17 +08:00
|
|
|
This can cause problems if you need characters that aren't available in
|
|
|
|
PrintableStrings and you don't want to or can't use BMPStrings.
|
|
|
|
|
|
|
|
As a consequence of the T61String handling the only correct way to represent
|
|
|
|
accented characters in OpenSSL is to use a BMPString: unfortunately Netscape
|
|
|
|
currently chokes on these. If you have to use accented characters with Netscape
|
|
|
|
and MSIE then you currently need to use the invalid T61String form.
|
|
|
|
|
2000-01-20 09:37:17 +08:00
|
|
|
The current prompting is not very friendly. It doesn't allow you to confirm what
|
|
|
|
you've just entered. Other things like extensions in certificate requests are
|
|
|
|
statically defined in the configuration file. Some of these: like an email
|
|
|
|
address in subjectAltName should be input by the user.
