NAME
wotsap - Web of Trust statistics and pathfinder
SYNOPSIS
wotsap [OPTIONS] [bottomkey [topkey]]
DESCRIPTION
wotsap is a pathfinder for the OpenPGP Web of Trust, which also produces some statistics
and similar things. It obtains the description of the Web of Trust from a .wot file.
OpenPGP is the most widely used email encryption standard, used by encryption software
such as the GNU Privacy Guard (see gnupg (7)). To encrypt to someone or verify someone's
signature, you need that persons OpenPGP key. Say you want to verify a digital signature
made by Bob. To get Bob's key is easy with some help from keyservers, being sure you got
the right key is the tricky part. This is accomplished either by meeting Bob in person and
exchanging signatures, or by trusting someone else, who you have met in person, who claims
to have met Bob. Or by trusting someone who has met someone who has met Bob. This gives
rise to a completely decentralized network of trusts between people.
wotsap lets you explore the Web of Trust. It works on a compressed copy of the Web of
Trust in the .wot file format, generated daily and distributed on the site of wotsap main
writer.
Running wotsap you can specify on the command line just bottomkey, bottomkey and topkey or
neither of them. They are the hexadecimal ID of the keys you want to investigate:
· If you don't specify any of bottomkey and topkey, wotsap will just produce some piece
of information on the Wot of Trust, such as the total number of key and signatures and
the average signatures per key.
· If you specify only bottomkey, wotsap will output detailed statistics about that key:
how far are the other key in the Web from this, the Mean Shortest Distance for this
key, which key have signed this key or are signed by this key. The Mean Shortest
Distance is the average of the distances from all the keys in the Web of Trust to the
key you under considaration. The distance from a key to another is the length of a
minimal path from the first to the second.
· If you specify either bottomkey and topkey, wotsap will search for all the minimal
paths from bottomkey to topkey and output them.
OPTIONS
-h --help
Show help.
--version
Show version.
-w --wot=FILE
Read Web of Trust information from FILE. Defaults to ~/.wotsapdb. You can find the
latest version of this file (generated daily) at
http://www.lysator.liu.se/~jc/wotsap/wots2/latest.wot.
-m --modify=STR
Use STR of WoT modification string.
-g --group
Print signature matrix of comma separated keys. If there aren't any commas in the key
specification, wotsap will interpret it as a search string, and print the signature
matrix of all the key, whose name or email contains the string.
-G --nounknowns
Don't print unknown keys in the signature matrix.
-o --png=FILE
Write an image of the graph of all the minimal paths between the two specified keys in
FILE, in .png file format.
-O --show-png=PRG
Like -o, but shows the image with PRG instead of writing it in a file. More precisely,
it saves the minimal paths image in a temporary file, the executes 'PRG image_file'
and, when PRG is over, deletes the temporary file.
-s --size=NNNxMMM
With -o or -O options, set the size of the generated image to NNNxMMM.
-F --font=FILE
Use FILE as the font file, in .pil/.pbm format. Point it to the .pil file, with the
.pbm file in the same directory. If no font specifications are given, wotsap will try
to use some fonts installed in the system, or fall back to a built-in one.
-T --ttffont=FILE
Like -F, but with a TrueType font file.
-S --ttfsize=NUM
With -T, set the TrueType font size. Defaults to 16.
-p --print
Print the whole Web of Trust in human readable format (very long output).
-D --print-debug
Print the debug information in the .wot file.
-d --diff=FILE
Print all differences between two .wot files (namely, between the file specified with
-w and that specified with this option).
-M --msd
Just show MSD for the specified key instead of full statistics.
-W --wanted[=NUM]
Show the NUM (defaults to 10) 'most wanted signatures' for key (very long calculation
time, try using -r).
-r --restrict=STR
Restrict wanted signatures with STR, implies -W.
