.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "CA.PL 1" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
CA.pl - friendlier interface for OpenSSL certificate programs Header "SYNOPSIS" \fB\s-1CA\s0.pl \fB-? | \fB-h | \fB-help

\fB\s-1CA\s0.pl \fB-newcert | \fB-newreq | \fB-newreq-nodes | \fB-xsign | \fB-sign | \fB-signCA | \fB-signcert | \fB-crl | \fB-newca [-extra-\f(BIcmd parameter]

\fB\s-1CA\s0.pl -pkcs12 [certname]

\fB\s-1CA\s0.pl -verify certfile ...

\fB\s-1CA\s0.pl -revoke certfile [reason]

Header "DESCRIPTION" The \s-1CA\s0.pl script is a perl script that supplies the relevant command line arguments to the openssl\|(1) command for some common certificate operations. It is intended to simplify the process of certificate creation and management by the use of some simple options.

The script is intended as a simple front end for the openssl\|(1) program for use by a beginner. Its behaviour isn't always what is wanted. For more control over the behaviour of the certificate commands call the openssl\|(1) command directly.

Most of the filenames mentioned below can be modified by editing the \fB\s-1CA\s0.pl script.

Under some environments it may not be possible to run the \s-1CA\s0.pl script directly (for example Win32) and the default configuration file location may be wrong. In this case the command:

.Vb 1 perl -S CA.pl .Ve

can be used and the \s-1OPENSSL_CONF\s0 environment variable can be set to point to the correct path of the configuration file.

Header "OPTIONS" Item "-?, -h, -help" Prints a usage message. Item "-newcert" Creates a new self signed certificate. The private key is written to the file \fInewkey.pem and the request written to the file newreq.pem. Invokes openssl-req\|(1). Item "-newreq" Creates a new certificate request. The private key is written to the file \fInewkey.pem and the request written to the file newreq.pem. Executes openssl-req\|(1) under the hood. Item "-newreq-nodes" Is like -newreq except that the private key will not be encrypted. Uses openssl-req\|(1). Item "-newca" Creates a new \s-1CA\s0 hierarchy for use with the ca program (or the -signcert and -xsign options). The user is prompted to enter the filename of the \s-1CA\s0 certificates (which should also contain the private key) or by hitting \s-1ENTER\s0 details of the \s-1CA\s0 will be prompted for. The relevant files and directories are created in a directory called demoCA in the current directory. Uses openssl-req\|(1) and openssl-ca\|(1). .Sp If the demoCA directory already exists then the -newca command will not overwrite it and will do nothing. This can happen if a previous call using the -newca option terminated abnormally. To get the correct behaviour delete the directory if it already exists. Item "-pkcs12" Create a PKCS#12 file containing the user certificate, private key and \s-1CA\s0 certificate. It expects the user certificate and private key to be in the file newcert.pem and the \s-1CA\s0 certificate to be in the file demoCA/cacert.pem, it creates a file newcert.p12. This command can thus be called after the \fB-sign option. The PKCS#12 file can be imported directly into a browser. If there is an additional argument on the command line it will be used as the \*(L"friendly name\*(R" for the certificate (which is typically displayed in the browser list box), otherwise the name \*(L"My Certificate\*(R" is used. Delegates work to openssl-pkcs12\|(1). Item "-sign, -signcert, -xsign" Calls the openssl-ca\|(1) command to sign a certificate request. It expects the request to be in the file newreq.pem. The new certificate is written to the file newcert.pem except in the case of the -xsign option when it is written to standard output. Item "-signCA" This option is the same as the -sign option except it uses the configuration file section v3_ca and so makes the signed request a valid \s-1CA\s0 certificate. This is useful when creating intermediate \s-1CA\s0 from a root \s-1CA.\s0 Extra params are passed to openssl-ca\|(1). Item "-signcert" This option is the same as -sign except it expects a self signed certificate to be present in the file newreq.pem. Extra params are passed to openssl-x509\|(1) and openssl-ca\|(1). Item "-crl" Generate a \s-1CRL.\s0 Executes openssl-ca\|(1). Item "-revoke certfile [reason]" Revoke the certificate contained in the specified certfile. An optional reason may be specified, and must be one of: unspecified, \fBkeyCompromise, CACompromise, affiliationChanged, superseded, \fBcessationOfOperation, certificateHold, or removeFromCRL. Leverages openssl-ca\|(1). Item "-verify" Verifies certificates against the \s-1CA\s0 certificate for demoCA. If no certificates are specified on the command line it tries to verify the file \fInewcert.pem. Invokes openssl-verify\|(1). Item "-extra-cmd parameter" For each option extra-\f(BIcmd, pass parameter to the openssl\|(1) sub-command with the same name as cmd, if that sub-command is invoked. For example, if openssl-req\|(1) is invoked, the parameter given with \fB-extra-req will be passed to it. For multi-word parameters, either repeat the option or quote the parameters so it looks like one word to your shell. See the individual command documentation for more information. Header "EXAMPLES" Create a \s-1CA\s0 hierarchy:

.Vb 1 CA.pl -newca .Ve

Complete certificate creation example: create a \s-1CA,\s0 create a request, sign the request and finally create a PKCS#12 file containing it.

.Vb 4 CA.pl -newca CA.pl -newreq CA.pl -sign CA.pl -pkcs12 "My Test Certificate" .Ve

Header "ENVIRONMENT" The environment variable \s-1OPENSSL\s0 may be used to specify the name of the OpenSSL program. It can be a full pathname, or a relative one.

The environment variable \s-1OPENSSL_CONFIG\s0 may be used to specify a configuration option and value to the req and ca commands invoked by this script. It's value should be the option and pathname, as in \f(CW\*(C`-config /path/to/conf-file\*(C'.
