Creates a .dot file from a gpg signature listing

Usage

Overview

This manual page documents briefly the sig2dot command. Sig2dot parses the output of "gpg --list-sigs" and produces a .dot file that can be used as input to a graphing program.

Options

sig2dot accepts the following options:

-b

Black and white / do not colorize.

-d <date>

Render graph as it appeared on <date> (ignores more recent signatures). Date must be in the format "YYYY-MM-DD". Will also ignore keys that have since been revoked.

-s <html-file-name>

Produces a sory HTML statistics file with the number of signatures per node.

-a

Graph all keys, even if they do not have a signature

-r <key-revoked-string>

Sets the text for the key-revoked string used by GnuPG. The default is what is used in the English version. This parameter can be set for versions of GnuPG localized to other languages. Default: "[revoked".

-t <title>

Sets the title for the graph generated. Default: "Keyring Statistics".

-u <user-not-found-string>

Sets the text for the user-not-found string used by GnuPG. The default is what is used in the English version. This parameter can be set for versions of GnuPG localized to other languages. Default: "[user id not found]".

-q

-h

Print help and exit.
