PGPlib is a library that lets you generate (and manipulate) PGP
|
|
packets without having to run PGP. In particular there is code to
|
|
generate and understand the following types of PGP packets:
|
|
|
|
- Data can be signed with a private key
|
|
- Data can be encrypted with a public key
|
|
- Data encrypted with your public key can be decrypted
|
|
- You can verify signatures on public keys and on buffers (files)
|
|
- Convential encrypted (IDEA with Zimmermann's context sensitive
|
|
feedback). The library can both read (decrypt) and write
|
|
(encrypt) convential packets (in PGP format)
|
|
- Armor. You can (de)armor a buffer or a file into a buffer or a
|
|
file
|
|
- UserID packets are read and written in a variety of formats
|
|
- Literal with filename, mode, etc. You can create literate
|
|
packages from files, or from buffers, and create files from
|
|
literate packets
|
|
- Keys can be obtained from a database (which is provided) or by
|
|
parsing keyrings. Keys can be kept in buffers or on files
|
|
- You can maintain a PGP public-key database (I use this library to
|
|
maintain a database with ~40.000 keys). There is code to use DBM
|
|
as supplied from Berkeley. A copy of DBM is included for your
|
|
convenience
|
|
|
|
In general, PGPlib operates on buffers in order for you to use it in
|
|
your applications.
|
|
|
|
I have made a small program that will (de)armor anything, a parser
|
|
to parse PGP files (including decryption and so on), a shell to
|
|
manipulate a keydatabase, a keyserver to run on top of such a
|
|
database, a program to verify signatures on keys and/or files, a
|
|
program to split keyrings in smaller parts and a program that will
|
|
sign files for you. You will find all these (and many more) in the
|
|
PGPlib-1.1/applications/ directory. None of these uses PGP as they
|
|
are linked with PGPlib, which provides all the functionality that is
|
|
needed.
|
|
|
|
I believe that all parts of the library is tested against PGP by the
|
|
script PGPlib-1.1/applications/test.sh. You need to edit it in
|
|
order to make it run (to ensure that you read my warnings, sorry
|
|
about this).

What is not there for you
|
|
=========================
|
|
|
|
- Sufficient documentation.
|
|
|
|
I have written this library because I need it. In order to make
|
|
life less hard for my students, I will have to provide some
|
|
documentation. Possibly even on-line. However, quite a few manual
|
|
pages are included in the PGPlib-1.1/man/ directory.
