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.
87 =item B<--key-file> I<file>
89 Import keys from file. Can be supplied more than once.
97 =item $HOME/.caffrc - configuration file
99 =item $HOME/.caff/keys/yyyy-mm-dd/ - processed keys
101 =item $HOME/.caff/gnupghome/ - caff's working dir for gpg
103 =item $HOME/.caff/gnupghome/gpg.conf - gpg configuration
105 useful options include use-agent, keyserver-options, default-cert-level, etc.
109 =head1 CONFIGURATION FILE OPTIONS
111 The configuration file is a perl script that sets values in the hash B<%CONFIG>.
112 The file is generated when it does not exist.
116 $CONFIG{'owner'} = q{Peter Palfrader};
117 $CONFIG{'email'} = q{peter@palfrader.org};
118 $CONFIG{'keyid'} = [ qw{DE7AAF6E94C09C7F 62AF4031C82E0039} ];
120 =head2 Required basic settings
124 =item B<owner> [string]
126 Your name. B<REQUIRED>.
128 =item B<email> [string]
130 Your email address, used in From: lines. B<REQUIRED>.
132 =item B<keyid> [list of keyids]
134 A list of your keys. This is used to determine which signatures to keep
135 in the pruning step. If you select a key using B<-u> it has to be in
136 this list. B<REQUIRED>.
138 =head2 General settings
140 =item B<caffhome> [string]
142 Base directory for the files caff stores. Default: B<$HOME/.caff/>.
144 =head2 GnuPG settings
146 =item B<gpg> [string]
148 Path to the GnuPG binary. Default: B<gpg>.
150 =item B<gpg-sign> [string]
152 Path to the GnuPG binary which is used to sign keys. Default: what
155 =item B<gpg-delsig> [string]
157 Path to the GnuPG binary which is used to split off signatures. This was
158 needed while the upstream GnuPG was not fixed. Default: what B<gpg>
161 =item B<secret-keyring> [string]
163 Path to your secret keyring. Default: B<$HOME/.gnupg/secring.gpg>.
165 =item B<also-encrypt-to> [keyid, or list of keyids]
167 Additional keyids to encrypt messages to. Default: none.
169 =item B<gpg-sign-args> [string]
171 Additional commands to pass to gpg after the "sign" command.
174 =head2 Keyserver settings
176 =item B<keyserver> [string]
178 Keyserver to download keys from. Default: B<subkeys.pgp.net>.
180 =item B<no-download> [boolean]
182 If true, then skip the step of fetching keys from the keyserver.
185 =item B<key-files> [list of files]
187 A list of files containing keys to be imported.
189 =head2 Signing settings
191 =item B<no-sign> [boolean]
193 If true, then skip the signing step. Default: B<0>.
195 =item B<ask-sign> [boolean]
197 If true, then pause before continuing to the signing step.
198 This is useful for offline signing. Default: B<0>.
200 =item B<export-sig-age> [seconds]
202 Don't export UIDs by default, on which your latest signature is older
203 than this age. Default: B<24*60*60> (i.e. one day).
205 =item B<local-user> [keyid, or list of keyids]
207 Select the key that is used for signing, in case you have more than one key.
208 With multiple keyids, sign with each key in turn.
212 =item B<mail> [boolean]
214 Whether to send mails. This is a quad-option, with which you can set the
215 behaviour: yes always sends, no never sends; ask-yes and ask-no asks, for
216 each uid, with according defaults for the question. Default: B<ask-yes>.
218 In any case, the messages are also written to $CONFIG{'caffhome'}/keys/
220 =item B<mail-template> [string]
222 Email template which is used as the body text for the email sent out
223 instead of the default text if specified. The following perl variables
224 can be used in the template:
228 =item B<{owner}> [string]
230 Your name as specified in the L<B<owner>|/item_owner__5bstring_5d> setting.
232 =item B<{key}> [string]
234 The keyid of the key you signed.
236 =item B<{@uids}> [array]
238 The UIDs for which signatures are included in the mail.
242 =item B<reply-to> [string]
244 Add a Reply-To: header to messages sent. Default: none.
246 =item B<bcc> [string]
248 Address to send blind carbon copies to when sending mail.
251 =item B<mailer-send> [array]
253 Parameters to pass to Mail::Mailer.
254 This could for example be
256 $CONFIG{'mailer-send'} = [ 'smtp', Server => 'mail.server', Auth => ['user', 'pass'] ];
258 to use the perl SMTP client or
260 $CONFIG{'mailer-send'} = [ 'sendmail', '-o8' ];
262 to pass arguments to the sendmail program.
263 For more information run C<< perldoc Mail::Mailer >>.
264 Setting this option is strongly discouraged. Fix your local MTA

1342 If you have multiple user ids
, I sent the signature
for each user id
1343 separately to that user id
's associated email address. You can import
1344 the signatures by running each through `gpg --import`.
1346 Note that I did not upload your key to any keyservers. If you want this
1347 new signature to be available to others, please upload it yourself.
1348 With GnuPG this can be done using
1349 gpg --keyserver subkeys.pgp.net --send-key {$key}
1351 If you have any questions, don't hesitate to ask
