43 =item B<caff> [-eERS] [-m I<yes|ask-yes|ask-no|no>] [-u I<yourkeyid>] I<keyid> [I<keyid> ..]
49 CA Fire and Forget is a script that helps you in keysigning. It takes a list
50 of keyids on the command line, fetches them from a keyserver and calls GnuPG so
51 that you can sign it. It then mails each key to all its email addresses - only
52 including the one UID that we send to in each mail, pruned from all but self
53 sigs and sigs done by you. The mailed key is encrypted with itself as a means
54 to verify that key belongs to the recipient.
60 =item B<-e>, B<--export-old>
62 Export old signatures. Default is to ask the user for each old signature.
64 =item B<-E>, B<--no-export-old>
66 Do not export old signatures. Default is to ask the user for each old
69 =item B<-m>, B<--mail> I<yes|ask-yes|ask-no|no>
71 Whether to send mail after signing. Default is to ask, for each uid,
72 with a default value of yes.
74 =item B<-R>, B<--no-download>
76 Do not retrieve the key to be signed from a keyserver.
78 =item B<-S>, B<--no-sign>
82 =item B<-u> I<yourkeyid>, B<--local-user> I<yourkeyid>
84 Select the key that is used for signing, in case you have more than one key.
85 To sign with multiple keys at once, separate multiple keyids by comma. This
86 option requires the key(s) to be defined through the keyid variable in the
89 =item B<--key-file> I<file>
91 Import keys from file. Can be supplied more than once.
93 =item B<--keys-from-gnupg>
95 Try to import keys from your standard GnuPG keyrings.
103 =item $HOME/.caffrc - configuration file
105 =item $HOME/.caff/keys/yyyy-mm-dd/ - processed keys
107 =item $HOME/.caff/gnupghome/ - caff's working dir for gpg
109 =item $HOME/.caff/gnupghome/gpg.conf - gpg configuration
111 useful options include use-agent, keyserver-options, default-cert-level, etc.
115 =head1 CONFIGURATION FILE OPTIONS
117 The configuration file is a perl script that sets values in the hash B<%CONFIG>.
118 The file is generated when it does not exist.
122 $CONFIG{'owner'} = q{Peter Palfrader};
123 $CONFIG{'email'} = q{peter@palfrader.org};
124 $CONFIG{'keyid'} = [ qw{DE7AAF6E94C09C7F 62AF4031C82E0039} ];
126 =head2 Required basic settings
130 =item B<owner> [string]
132 Your name. B<REQUIRED>.
134 =item B<email> [string]
136 Your email address, used in From: lines. B<REQUIRED>.
138 =item B<keyid> [list of keyids]
140 A list of your keys. This is used to determine which signatures to keep
141 in the pruning step. If you select a key using B<-u> it has to be in
142 this list. B<REQUIRED>.
146 =head2 General settings
150 =item B<caffhome> [string]
152 Base directory for the files caff stores. Default: B<$HOME/.caff/>.
156 =head2 GnuPG settings
160 =item B<gpg> [string]
162 Path to the GnuPG binary. Default: B<gpg>.
164 =item B<gpg-sign> [string]
166 Path to the GnuPG binary which is used to sign keys. Default: what
169 =item B<gpg-delsig> [string]
171 Path to the GnuPG binary which is used to split off signatures. This was
172 needed while the upstream GnuPG was not fixed. Default: what B<gpg>
175 =item B<secret-keyring> [string]
177 Path to your secret keyring. Default: B<$HOME/.gnupg/secring.gpg>.
179 =item B<also-encrypt-to> [keyid, or list of keyids]
181 Additional keyids to encrypt messages to. Default: none.
183 =item B<gpg-sign-args> [string]
185 Additional commands to pass to gpg after the "sign" command.
190 =head2 Keyserver settings
194 =item B<keyserver> [string]
196 Keyserver to download keys from. Default: B<pool.sks-keyservers.net>.
198 =item B<no-download> [boolean]
200 If true, then skip the step of fetching keys from the keyserver.
203 =item B<key-files> [list of files]
205 A list of files containing keys to be imported.
209 =head2 Signing settings
213 =item B<no-sign> [boolean]
215 If true, then skip the signing step. Default: B<0>.
217 =item B<ask-sign> [boolean]
219 If true, then pause before continuing to the signing step.
220 This is useful for offline signing. Default: B<0>.
222 =item B<export-sig-age> [seconds]
224 Don't export UIDs by default, on which your latest signature is older
225 than this age. Default: B<24*60*60> (i.e. one day).
227 =item B<local-user> [keyid, or list of keyids]
229 Select the key that is used for signing, in case you have more than one key.
230 With multiple keyids, sign with each key in turn.
238 =item B<mail> [boolean]
240 Whether to send mails. This is a quad-option, with which you can set the
241 behaviour: yes always sends, no never sends; ask-yes and ask-no asks, for
242 each uid, with according defaults for the question. Default: B<ask-yes>.
244 In any case, the messages are also written to $CONFIG{'caffhome'}/keys/
246 =item B<mail-template> [string]
248 Email template which is used as the body text for the email sent out
249 instead of the default text if specified. The following perl variables
250 can be used in the template:
254 =item B<{owner}> [string]
256 Your name as specified in the L<B<owner>|/item_owner__5bstring_5d> setting.
258 =item B<{key}> [string]
260 The keyid of the key you signed.
262 =item B<{@uids}> [array]
264 The UIDs for which signatures are included in the mail.
268 =item B<reply-to> [string]
270 Add a Reply-To: header to messages sent. Default: none.
272 =item B<bcc> [string]
274 Address to send blind carbon copies to when sending mail.
277 =item B<mailer-send> [array]
279 Parameters to pass to Mail::Mailer.
280 This could for example be
282 $CONFIG{'mailer-send'} = [ 'smtp', Server => 'mail.server', Auth => ['user', 'pass'] ];
284 to use the perl SMTP client or
286 $CONFIG{'mailer-send'} = [ 'sendmail', '-o8' ];
288 to pass arguments to the sendmail program.
289 For more information run C<< perldoc Mail::Mailer >>.
290 Setting this option is strongly discouraged. Fix your local MTA
