NAME¶

caff -- CA - Fire and Forget

SYNOPSIS¶

caff [-eERS] [-m yes|ask-yes|ask-no|no] [-u yourkeyid] keyid [keyid ..]

DESCRIPTION¶

CA Fire and Forget is a script that helps you in keysigning. It takes a list of keyids on the command line, fetches them from a keyserver and calls GnuPG so that you can sign it. It then mails each key to all its email addresses - only including the one UID that we send to in each mail, pruned from all but self sigs and sigs done by you. The mailed key is encrypted with itself as a means to verify that key belongs to the recipient.

OPTIONS¶

-e, --export-old

Export old signatures. Default is to ask the user for each old signature.

-E, --no-export-old

Do not export old signatures. Default is to ask the user for each old signature.

-m, --mail yes|ask-yes|ask-no|no

Whether to send mail after signing. Default is to ask, for each uid, with a default value of yes.

-R, --no-download

Do not retrieve the key to be signed from a keyserver.

-S, --no-sign

Do not sign the keys.

-u yourkeyid, --local-user yourkeyid

Select the key that is used for signing, in case you have more than one key. To sign with multiple keys at once, separate multiple keyids by comma. This option requires the key(s) to be defined through the keyid variable in the configuration file.

--key-file file

Import keys from file. Can be supplied more than once.

--keys-from-gnupg file

Try to import keys from your standard GnuPG keyrings.

FILES¶

$HOME/.caffrc - configuration file

$HOME/.caff/keys/yyyy-mm-dd/ - processed keys

$HOME/.caff/gnupghome/ - caff's working dir for gpg

$HOME/.caff/gnupghome/gpg.conf - gpg configuration

useful options include use-agent, keyserver-options, default-cert-level, etc.

CONFIGURATION FILE OPTIONS¶

The configuration file is a perl script that sets values in the hash %CONFIG . The file is generated when it does not exist. Example:

        $CONFIG{'owner'} = q{Peter Palfrader};
        $CONFIG{'email'} = q{peter@palfrader.org};
        $CONFIG{'keyid'} = [ qw{DE7AAF6E94C09C7F 62AF4031C82E0039} ];

Required basic settings¶

owner [string]

Your name. REQUIRED.

email [string]

Your email address, used in From: lines. REQUIRED.

keyid [list of keyids]

A list of your keys. This is used to determine which signatures to keep in the pruning step. If you select a key using -u it has to be in this list. REQUIRED.

General settings¶

caffhome [string]

Base directory for the files caff stores. Default: $HOME/.caff/.

GnuPG settings¶

gpg [string]

Path to the GnuPG binary. Default: gpg.

gpg-sign [string]

Path to the GnuPG binary which is used to sign keys. Default: what gpg is set to.

gpg-delsig [string]

Path to the GnuPG binary which is used to split off signatures. This was needed while the upstream GnuPG was not fixed. Default: what gpg is set to.

secret-keyring [string]

Path to your secret keyring. Default: $HOME/.gnupg/secring.gpg.

also-encrypt-to [keyid, or list of keyids]

Additional keyids to encrypt messages to. Default: none.

gpg-sign-args [string]

Additional commands to pass to gpg after the "sign" command. Default: none.

Keyserver settings¶

keyserver [string]

Keyserver to download keys from. Default: pool.sks-keyservers.net.

no-download [boolean]

If true, then skip the step of fetching keys from the keyserver. Default: 0.

key-files [list of files]

A list of files containing keys to be imported.

Signing settings¶

no-sign [boolean]

If true, then skip the signing step. Default: 0.

ask-sign [boolean]

If true, then pause before continuing to the signing step. This is useful for offline signing. Default: 0.

export-sig-age [seconds]

Don't export UIDs by default, on which your latest signature is older than this age. Default: 24*60*60 (i.e. one day).

local-user [keyid, or list of keyids]

Select the key that is used for signing, in case you have more than one key. With multiple keyids, sign with each key in turn.

Mail settings¶

mail [boolean]

Whether to send mails. This is a quad-option, with which you can set the behaviour: yes always sends, no never sends; ask-yes and ask-no asks, for each uid, with according defaults for the question. Default: ask-yes.

 

In any case, the messages are also written to $CONFIG{'caffhome'}/keys/

mail-template [string]

Email template which is used as the body text for the email sent out instead of the default text if specified. The following perl variables can be used in the template:

reply-to [string]

Add a Reply-To: header to messages sent. Default: none.

bcc [string]

Address to send blind carbon copies to when sending mail. Default: none.

mailer-send [array]

Parameters to pass to Mail::Mailer. This could for example be

 

        $CONFIG{'mailer-send'} =  [ 'smtp', Server => 'mail.server', Auth => ['user', 'pass'] ];
    

 

to use the perl SMTP client or

 

        $CONFIG{'mailer-send'} =  [ 'sendmail', '-o8' ];
    

 

to pass arguments to the sendmail program. For more information run "perldoc Mail::Mailer". Setting this option is strongly discouraged. Fix your local MTA instead. Default: none.
