\subsection{bpg: BSD licensed privacy guard (pgp)}
\cfoot{\includegraphics[scale=0.25]{figs/netbsd-google.eps}}

BPG, the BSD Privacy Guard, is a BSD-licensed program that performs
authentication and encryption using the OpenPGP standard (RFC 2440).
\\

It provides:
\begin{itemize}
	\item A set of libraries for signing and encrypting data, allowing the
     integration of OpenPGP features in other applications.
	\item A modular ``PGP cryptography toolkit'' that allow users to chose
      their own encryption and signing algorithms, key management
      structure, and so on.
	\item A scriptable and well thought command-line interface built over
      the libraries. This standalone application will be a suitable
      replacement for GnuPG or PGP.
\end{itemize}

\subsection{bpg: main uses}
The main uses supported are:
\begin{itemize}
	\item Data confidentiality: the library must support different algorithms
 for encryption of data. Concretely, it aims to be used for symmetric
  and asymmetric encryption.
	\item Data integrity and authentication: via digital signatures, BPG will
  support providing integrity and authentication to data, as defined
  in OpenPGP standard.
	\item Integrated key management: BPG aims to support centralized management
  of all of a user's public and private keys.
\end{itemize}

\subsection{bpg: Goals}
\begin{itemize}
	\item Provide a complete implementation of the OpenPGP standard, with the
  only exception of possible old formats incompatibility if project
  needs demands it.
	\item  Settle on the basis of a well-thought and well-designed data security
  framework.
	\item Develop command-line interface that is both:
	\begin{itemize}
		\item powerful: it must support all the program functionality in
	an easily scriptable way;
		\item usable: confusing user interfaces reduce security by
	making it harder for a user to make correct decisions.
	\end{itemize}
	\item Design the libraries for extensibility. We'd like BPG to be a good
  field for developing researchs in the state-of-the-art of
  authentication and cryptography.
	\item Make BPG a good candidate to replace GnuPG usage in BSD Unixes.
\end{itemize}

\subsection{bgp: Architecture}
The main goal of BPG is to provide applications with a toolkit for
using OpenPGP facilities. For that, functionality was packed into
libraries. \\

There are four libraries, corresponding with the four problems BPG
tries to solve:
\begin{itemize}
	\item securing data
	\item key management
	\item trust management
	\item algorithms
\end{itemize}

\subsection{bgp: Architecture: Securing data}
Library name: {\tt libbpg} \\

Relies on other libraries:
\begin{itemize}
	\item Key management library: PKI keys are especified in the API with
  user-IDs and obtained from the BPG key management library. The key
  management library is the responsible of key decryption if
  necessary.
	\item Algorithms library: for performing low-level encryption, hashing and
  compression, it uses the BPG algorithms library.
	\item Compression library: BPG will use libzip for compression
\end{itemize}

\subsection{bgp: Architecture: Key Management}
Library name: {\tt libbpgkey} \\

The key managament library is divided into a set of specialized
submodules:
\begin{itemize}
	\item Key fetcher: receives petitions for a key and performs the necessary
  operations to give it back to the user (or say why it wasn't
  possible).
	\item Key generator: receives petitions for creating asymmetric or
  symmetric keys.
	\item Key importer/exporter: this module receives petitions from the user
  to take a key from a location A and insert it into location B, where
  A and B can be files, keyrings or key servers.
	\item Key interpreter: translates OpenPGP packets containing keys into the
  internal data structure for keys and viceversa.
	\item Key deliverer: with no public functions, this module performs the
  internal checkouts and commits of keys from and to a file, keyring
  or key server.
\end{itemize}

\subsection{bgp: Architecture: Trust Management}
Library name: {\tt libbpgtrust} \\

The trust library handles the trust database and the trust policy. The trust
database contains a list of \[UserID, trust level\] pairs. The policy defines
the rules for deriving the trust level of a given key from the trust database
(i.e. OpenPGP web of trust, X.509 hierarchical trust model, ...).

\subsection{bgp: Architecture: Algorithms}
Library name: {\tt libbpgalgo} \\

The initial algorithms supported will be:
\begin{itemize}
	\item Hash functions: SHA-1.
	\item Symmetric algorithms: AES.
	\item Asymmetric algorithms: RSA, DSA.
\end{itemize}
\vspace{.5in}
{\tt libbpgalgo} may offer with a plugins system would take the
extensibility and reusability to a higher level.

\subsection{bpg: Security Issues}
\begin{itemize}
	\item Memory purge
	\item Integrity of the keyring
	\item MITM attacks
	\item Emission captures
	\item Time-based attacks
	\item Password sniffing
