siggraph ======== siggraph is a small Ruby program that formats your GnuPG web of trust as a Graphviz file, which you can then use as input to a tool like twopi(1) that will draw it as a nice graph. The basic usage is simple. Invoke the program with the ID of the key that you want to use as the start point (centre) of the web of of trust graph, and redirect the output to a file or directly pipe it into one of the Graphviz tools: $ siggraph 1111111 > wot.dot $ siggraph 1111111 | twopi -Tpdf -o wot.pdf The program supports a few options that change the graph’ſ appearence. Invoke it with the “-h” option to get a list with explanations. siggraph depends only on GnuPG and the Ruby interpreter itself, no further requirements must be met on this side. If you want to run it on a non-POSIX platform, you’ll probably need to supply the “-g” option, because by default it tries to redirect GnuPG’s error stream to /dev/null otherwise. Note that officially supported is only GnuPG version 2. The old version 1.42 may or may not work. The gpg(1) binary must be in your PATH for this program to work properly. If your web of trust is large, siggraph will take some time to generate the Graphviz file, but it should output a well-formatted script nevertheless. Still, Graphviz may not be able to handle it; I got twopi(1) to crash with a rather small web of trust already when I selected PNG output. This however is not siggraph’s domain; you’ll need to complain to the Graphviz developers for that. In the meantime, you can try outputting the graph in another format than PNG (PDF and SVG are nice ones), or with another tool (dot(1) seems to be more reliable than twopi(1) for example, but the graph doesn’t look as nice).
