# pgpdump: a PGP packet visualizer

- Kazu Yamamoto 

- August 16, 2010

## Overview

**pgpdump** is a PGP packet visualizer which displays the packet format of OpenPGP ([RFC 4880](https://datatracker.ietf.org/doc/html/rfc4880)) and PGP version 2 ([RFC 1991](https://datatracker.ietf.org/doc/html/rfc1991)).

Here is an example:

	% pgpdump test/sig1

	Old: Marker Packet(tag 10)(3 bytes)

		String - ...

	New: One-Pass Signature Packet(tag 4)(13 bytes)

		New version(3)

		Sig type - Signature of a binary document(0x00).

		Hash alg - SHA1(hash 2)

		Pub alg - DSA Digital Signature Algorithm(pub 17)

		Key ID - 0xA79778E247B63037

		Next packet - other than one pass signature

	New: Signature Packet(tag 2)(63 bytes)

		Ver 3 - old

		Hash material(5 bytes):

			Sig type - Signature of a binary document(0x00).

			Creation time - Fri Nov 27 22:35:02 JST 1998

		Key ID - 0xA79778E247B63037

		Pub alg - DSA Digital Signature Algorithm(pub 17)

		Hash alg - SHA1(hash 2)

		Hash left 2 bytes - 8f 82

		DSA r(160 bits) - ...

		DSA s(157 bits) - ...

			-> hash(DSA q bits)

## Installation

Take the following steps to install **pgpdump** from a release tarball:

	% ./configure

To build from Git, run `autoreconf -fviW all` before running the above commands.

Binaries are available for Mac OS X via Homebrew:

Some examples are stored in the `test` directory. Also, you can visualize your

pubring and secring.
