It can be used -to sign certificate requests in a variety of forms and generate -CRLs it also maintains a text database of issued certificates -and their status. - -The options descriptions will be divided into each purpose. - -=head1 CA OPTIONS - -=over 4 - -=item B<-config filename> - -specifies the configuration file to use. - -=item B<-name section> - -specifies the configuration file section to use (overrides -B<default_ca> in the B<ca> section). - -=item B<-in filename> - -an input filename containing a single certificate request to be -signed by the CA. - -=item B<-ss_cert filename> - -a single self signed certificate to be signed by the CA. - -=item B<-spkac filename> - -a file containing a single Netscape signed public key and challenge -and additional field values to be signed by the CA. See the B<NOTES> -section for information on the required format. - -=item B<-infiles> - -if present this should be the last option, all subsequent arguments -are assumed to the the names of files containing certificate requests. - -=item B<-out filename> - -the output file to output certificates to. The default is standard -output. The certificate details will also be printed out to this -file. - -=item B<-outdir directory> - -the directory to output certificates to. The certificate will be -written to a filename consisting of the serial number in hex with -".pem" appended. - -=item B<-cert> - -the CA certificate file. - -=item B<-keyfile filename> - -the private key to sign requests with. - -=item B<-key password> - -the password used to encrypt the private key. Since on some -systems the command line arguments are visible (e.g. Unix with -the 'ps' utility) this option should be used with caution. - -=item B<-passin arg> - -the key password source. For more information about the format of B<arg> -see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)|openssl(1)>. -=item B<-verbose> - -this prints extra details about the operations being performed. - -=item B<-notext> - -don't output the text form of a certificate to the output file. - -=item B<-startdate date> - -this allows the start date to be explicitly set. The format of the -date is YYMMDDHHMMSSZ (the same as an ASN1 UTCTime structure). - -=item B<-enddate date> - -this allows the expiry date to be explicitly set. The format of the -date is YYMMDDHHMMSSZ (the same as an ASN1 UTCTime structure). - -=item B<-days arg> - -the number of days to certify the certificate for. - -=item B<-md alg> - -the message digest to use. Possible values include md5, sha1 and mdc2. -This option also applies to CRLs. - -=item B<-policy arg> - -this option defines the CA "policy" to use. This is a section in -the configuration file which decides which fields should be mandatory -or match the CA certificate. Check out the B<POLICY FORMAT> section -for more information. - -=item B<-msie_hack> - -this is a legacy option to make B<ca> work with very old versions of -the IE certificate enrollment control "certenr3". It used UniversalStrings -for almost everything. Since the old control has various security bugs -its use is strongly discouraged. The newer control "Xenroll" does not -need this option. - -=item B<-preserveDN> - -Normally the DN order of a certificate is the same as the order of the -fields in the relevant policy section. When this option is set the order -is the same as the request. This is largely for compatibility with the -older IE enrollment control which would only accept certificates if their -DNs match the order of the request. This is not needed for Xenroll. - -=item B<-batch> - -this sets the batch mode. In this mode no questions will be asked -and all certificates will be certified automatically. - -=item B<-extensions section> - -the section of the configuration file containing certificate extensions -to be added when a certificate is issued. If no extension section is -present then a V1 certificate is created. If the extension section -is present (even if it is empty) then a V3 certificate is created. - -=back - -=head1 CRL OPTIONS - -=over 4 - -=item B<-gencrl> - -this option generates a CRL based on information in the index file. - -=item B<-crldays num> - -the number of days before the next CRL is due. That is the days from -now to place in the CRL nextUpdate field. - -=item B<-crlhours num> - -the number of hours before the next CRL is due. - -=item B<-revoke filename> - -a filename containing a certificate to revoke. - -=item B<-crlexts section> - -the section of the configuration file containing CRL extensions to -include. If no CRL extension section is present then a V1 CRL is -created, if the CRL extension section is present (even if it is -empty) then a V2 CRL is created. The CRL extensions specified are -CRL extensions and B<not> CRL entry extensions. It should be noted -that some software (for example Netscape) can't handle V2 CRLs. - -=back - -=head1 CONFIGURATION FILE OPTIONS - -The section of the configuration file containing options for B<ca> -is found as follows: If the B<-name> command line option is used, -then it names the section to be used. Otherwise the section to -be used must be named in the B<default_ca> option of the B<ca> section -of the configuration file (or in the default section of the -configuration file). Besides B<default_ca>, the following options are -read directly from the B<ca> section: - RANDFILE - preserve - msie_hack -With the exception of B<RANDFILE>, this is probably a bug and may -change in future releases. - -Many of the configuration file options are identical to command line -options. Where the option is present in the configuration file -and the command line the command line value is used. Where an -option is described as mandatory then it must be present in -the configuration file or the command line equivalent (if -any) used. - -=over 4 - -=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 -object identifiers. Each line should consist of the short name of the -object identifier followed by B<=> and the numerical form. The short -and long names are the same when this option is used. - -=item B<new_certs_dir> - -the same as the B<-outdir> command line option. It specifies -the directory where new certificates will be placed. Mandatory. - -=item B<certificate> - -the same as B<-cert>. It gives the file containing the CA -certificate. Mandatory. - -=item B<private_key> - -same as the B<-keyfile> option. The file containing the -CA private key. Mandatory. - -=item B<RANDFILE> - -a file used to read and write random number seed information, or -an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>). - -=item B<default_days> - -the same as the B<-days> option. The number of days to certify -a certificate for. - -=item B<default_startdate> - -the same as the B<-startdate> option. The start date to certify -a certificate for. If not set the current time is used. - -=item B<default_enddate> - -the same as the B<-enddate> option. Either this option or -B<default_days> (or the command line equivalents) must be -present. - -=item B<default_crl_hours default_crl_days> - -the same as the B<-crlhours> and the B<-crldays> options. These -will only be used if neither command line option is present. At -least one of these must be present to generate a CRL. - -=item B<default_md> - -the same as the B<-md> option. The message digest to use. Mandatory. - -=item B<database> - -the text database file to use. Mandatory. This file must be present -though initially it will be empty. - -=item B<serialfile> - -a text file containing the next serial number to use in hex. Mandatory. -This file must be present and contain a valid serial number. - -=item B<x509_extensions> - -the same as B<-extensions>. - -=item B<crl_extensions> - -the same as B<-crlexts>. - -=item B<preserve> - -the same as B<-preserveDN> - -=item B<msie_hack> - -the same as B<-msie_hack> - -=item B<policy> - -the same as B<-policy>. Mandatory. See the B<POLICY FORMAT> section -for more information. - -=back - -=head1 POLICY FORMAT - -The policy section consists of a set of variables corresponding to -certificate DN fields. If the value is "match" then the field value -must match the same field in the CA certificate. If the value is -"supplied" then it must be present. If the value is "optional" then -it may be present. Any fields not mentioned in the policy section -are silently deleted, unless the B<-preserveDN> option is set but -this can be regarded more of a quirk than intended behaviour. - -=head1 SPKAC FORMAT - -The input to the B<-spkac> command line option is a Netscape -signed public key and challenge. This will usually come from -the B<KEYGEN> tag in an HTML form to create a new private key. -It is however possible to create SPKACs using the B<spkac> utility. - -The file should contain the variable SPKAC set to the value of -the SPKAC and also the required DN components as name value pairs. -If you need to include the same component twice then it can be -preceded by a number and a '.'. - -=head1 EXAMPLES - -Note: these examples assume that the B<ca> directory structure is -already set up and the relevant files already exist. This usually -involves creating a CA certificate and private key with B<req>, a -serial number file and an empty index file and placing them in -the relevant directories. - -To use the sample configuration file below the directories demoCA, -demoCA/private and demoCA/newcerts would be created. The CA -certificate would be copied to demoCA/cacert.pem and its private -key to demoCA/private/cakey.pem. A file demoCA/serial would be -created containing for example "01" and the empty index file -demoCA/index.txt. - - -Sign a certificate request: - - openssl ca -in req.pem -out newcert.pem - -Sign a certificate request, using CA extensions: - - openssl ca -in req.pem -extensions v3_ca -out newcert.pem - -Generate a CRL - - openssl ca -gencrl -out crl.pem - -Sign several requests: - - openssl ca -infiles req1.pem req2.pem req3.pem - -Certify a Netscape SPKAC: - - openssl ca -spkac spkac.txt - -A sample SPKAC file (the SPKAC line has been truncated for clarity): - - SPKAC=MIG0MGAwXDANBgkqhkiG9w0BAQEFAANLADBIAkEAn7PDhCeV/xIxUg8V70YRxK2A5 - CN=Steve Test - emailAddress=steve@openssl.org - 0.OU=OpenSSL Group - 1.OU=Another Group - -A sample configuration file with the relevant sections for B<ca>: - - [ ca ] - default_ca = CA_default # The default ca section - - [ CA_default ] - - dir = ./demoCA # top dir - database = $dir/index.txt # index file. - new_certs_dir = $dir/newcerts # new certs dir - - certificate = $dir/cacert.pem # The CA cert - serial = $dir/serial # serial no file - private_key = $dir/private/cakey.pem# CA private key - RANDFILE = $dir/private/.rand # random number file - - default_days = 365 # how long to certify for - default_crl_days= 30 # how long before next CRL - default_md = md5 # md to use - - policy = policy_any # default policy - - [ policy_any ] - countryName = supplied - stateOrProvinceName = optional - organizationName = optional - organizationalUnitName = optional - commonName = supplied - emailAddress = optional - -=head1 WARNINGS - -The B<ca> command is quirky and at times downright unfriendly. - -The B<ca> utility was originally meant as an example of how to do things -in a CA. It was not supposed be be used as a full blown CA itself: -nevertheless some people are using it for this purpose. - -The B<ca> command is effectively a single user command: no locking is -done on the various files and attempts to run more than one B<ca> command -on the same database can have unpredictable results. - -=head1 FILES - -Note: the location of all files can change either by compile time options, -configuration file entries, environment variables or command line options. -The values below reflect the default values. - - /usr/local/ssl/lib/openssl.cnf - master configuration file - ./demoCA - main CA directory - ./demoCA/cacert.pem - CA certificate - ./demoCA/private/cakey.pem - CA private key - ./demoCA/serial - CA serial number file - ./demoCA/serial.old - CA serial number backup file - ./demoCA/index.txt - CA text database file - ./demoCA/index.txt.old - CA text database backup file - ./demoCA/certs - certificate output file - ./demoCA/.rnd - CA random seed information - -=head1 ENVIRONMENT VARIABLES - -B<OPENSSL_CONF> reflects the location of master configuration file it can -be overridden by the B<-config> command line option. - -=head1 RESTRICTIONS - -The text database index file is a critical part of the process and -if corrupted it can be difficult to fix. It is theoretically possible -to rebuild the index file from all the issued certificates and a current -CRL: however there is no option to do this. - -CRL entry extensions cannot currently be created: only CRL extensions -can be added. - -V2 CRL features like delta CRL support and CRL numbers are not currently -supported. - -Although several requests can be input and handled at once it is only -possible to include one SPKAC or self signed certificate. - -=head1 BUGS - -The use of an in memory text database can cause problems when large -numbers of certificates are present because, as the name implies -the database has to be kept in memory. - -Certificate request extensions are ignored: some kind of "policy" should -be included to use certain static extensions and certain extensions -from the request. - -It is not possible to certify two certificates with the same DN: this -is a side effect of how the text database is indexed and it cannot easily -be fixed without introducing other problems. Some S/MIME clients can use -two certificates with the same DN for separate signing and encryption -keys. - -The B<ca> command really needs rewriting or the required functionality -exposed at either a command or interface level so a more friendly utility -(perl script or GUI) can handle things properly. The scripts B<CA.sh> and -B<CA.pl> help a little but not very much. - -Any fields in a request that are not present in a policy are silently -deleted. This does not happen if the B<-preserveDN> option is used but -the extra fields are not displayed when the user is asked to certify -a request. The behaviour should be more friendly and configurable. - -Cancelling some commands by refusing to certify a certificate can -create an empty file. - -=head1 SEE ALSO - -L<req(1)|req(1)>, L<spkac(1)|spkac(1)>, L<x509(1)|x509(1)>, L<CA.pl(1)|CA.pl(1)>, -L<config(5)|config(5)> - -=cut |
