5 CA.pl - friendlier interface for OpenSSL certificate programs
24 [B<-extra-cmd> extra-params]
26 B<CA.pl> B<-pkcs12> [B<-extra-pkcs12> extra-params] [B<certname>]
28 B<CA.pl> B<-verify> [B<-extra-verify> extra-params] B<certfile>...
30 B<CA.pl> B<-revoke> [B<-extra-ca> extra-params] B<certfile> [B<reason>]
34 The B<CA.pl> script is a perl script that supplies the relevant command line
35 arguments to the B<openssl> command for some common certificate operations.
36 It is intended to simplify the process of certificate creation and management
37 by the use of some simple options.
43 =item B<?>, B<-h>, B<-help>
45 Prints a usage message.
49 Creates a new self signed certificate. The private key is written to the file
50 "newkey.pem" and the request written to the file "newreq.pem".
51 This argument invokes B<openssl req> command.
55 Creates a new certificate request. The private key is written to the file
56 "newkey.pem" and the request written to the file "newreq.pem".
57 Executes B<openssl req> command below the hood.
59 =item B<-newreq-nodes>
61 Is like B<-newreq> except that the private key will not be encrypted.
62 Uses B<openssl req> command.
66 Creates a new CA hierarchy for use with the B<ca> program (or the B<-signcert>
67 and B<-xsign> options). The user is prompted to enter the filename of the CA
68 certificates (which should also contain the private key) or by hitting ENTER
69 details of the CA will be prompted for. The relevant files and directories
70 are created in a directory called "demoCA" in the current directory.
71 B<openssl req> and B<openssl ca> commands are get invoked.
75 Create a PKCS#12 file containing the user certificate, private key and CA
76 certificate. It expects the user certificate and private key to be in the
77 file "newcert.pem" and the CA certificate to be in the file demoCA/cacert.pem,
78 it creates a file "newcert.p12". This command can thus be called after the
79 B<-sign> option. The PKCS#12 file can be imported directly into a browser.
80 If there is an additional argument on the command line it will be used as the
81 "friendly name" for the certificate (which is typically displayed in the browser
82 list box), otherwise the name "My Certificate" is used.
83 Delegates work to B<openssl pkcs12> command.
85 =item B<-sign>, B<-signcert>, B<-xsign>
87 Calls the B<ca> program to sign a certificate request. It expects the request
88 to be in the file "newreq.pem". The new certificate is written to the file
89 "newcert.pem" except in the case of the B<-xsign> option when it is written
90 to standard output. Leverages B<openssl ca> command.
94 This option is the same as the B<-signreq> option except it uses the
95 configuration file section B<v3_ca> and so makes the signed request a
96 valid CA certificate. This is useful when creating intermediate CA from
97 a root CA. Extra params are passed on to B<openssl ca> command.
101 This option is the same as B<-sign> except it expects a self signed certificate
102 to be present in the file "newreq.pem".
103 Extra params are passed on to B<openssl x509> and B<openssl ca> commands.
107 Generate a CRL. Executes B<openssl ca> command.
109 =item B<-revoke certfile [reason]>
111 Revoke the certificate contained in the specified B<certfile>. An optional
112 reason may be specified, and must be one of: B<unspecified>,
113 B<keyCompromise>, B<CACompromise>, B<affiliationChanged>, B<superseded>,
114 B<cessationOfOperation>, B<certificateHold>, or B<removeFromCRL>.
115 Leverages B<openssl ca> command.
119 Verifies certificates against the CA certificate for "demoCA". If no
120 certificates are specified on the command line it tries to verify the file
121 "newcert.pem". Invokes B<openssl verify> command.
123 =item B<-extra-req> | B<-extra-ca> | B<-extra-pkcs12> | B<-extra-x509> | B<-extra-verify> <extra-params>
125 The purpose of these parameters is to allow optional parameters to be supplied
126 to B<openssl> that this command executes. The B<-extra-cmd> are specific to the
127 option being used and the B<openssl> command getting invoked. For example
128 when this command invokes B<openssl req> extra parameters can be passed on
129 with the B<-extra-req> parameter. The
130 B<openssl> commands being invoked per option are documented below.
131 Users should consult B<openssl> command documentation for more information.
137 Create a CA hierarchy:
141 Complete certificate creation example: create a CA, create a request, sign
142 the request and finally create a PKCS#12 file containing it.
147 CA.pl -pkcs12 "My Test Certificate"
149 =head1 DSA CERTIFICATES
151 Although the B<CA.pl> creates RSA CAs and requests it is still possible to
152 use it with DSA certificates and requests using the L<req(1)> command
153 directly. The following example shows the steps that would typically be taken.
155 Create some DSA parameters:
157 openssl dsaparam -out dsap.pem 1024
159 Create a DSA CA certificate and private key:
161 openssl req -x509 -newkey dsa:dsap.pem -keyout cacert.pem -out cacert.pem
163 Create the CA directories and files:
167 enter cacert.pem when prompted for the CA file name.
169 Create a DSA certificate request and private key (a different set of parameters
170 can optionally be created first):
172 openssl req -out newreq.pem -newkey dsa:dsap.pem
180 Most of the filenames mentioned can be modified by editing the B<CA.pl> script.
182 If the demoCA directory already exists then the B<-newca> command will not
183 overwrite it and will do nothing. This can happen if a previous call using
184 the B<-newca> option terminated abnormally. To get the correct behaviour
185 delete the demoCA directory if it already exists.
187 Under some environments it may not be possible to run the B<CA.pl> script
188 directly (for example Win32) and the default configuration file location may
189 be wrong. In this case the command:
193 can be used and the B<OPENSSL_CONF> environment variable changed to point to
194 the correct path of the configuration file.
196 The script is intended as a simple front end for the B<openssl> program for use
197 by a beginner. Its behaviour isn't always what is wanted. For more control over the
198 behaviour of the certificate commands call the B<openssl> command directly.
