This is the README for Ironclad, a cryptography package for ANSI Common
Lisp.  It includes several popular block encryption algorithms and
several popular hash functions.  This release also includes some initial
public-key cryptography functionality with the addition of DSA signing
and verification.  (As a bonus, this software used to sign this release
was written in pure Common Lisp.)  This release is intended as a
prototype and as a basis for discussion and refinement.

Most of the algorithms were written with efficiency for specific Common
Lisp implementations in mind, although portable code is provided as an
alternative in nearly all instances.  The framework should be flexible
enough to accomodate implementation-specific optimizations when possible.

Documentation is currently minimal.  Documentation strings for most of
the exported functions should be provided; these strings provide a
decent overview of what the library is capable of.

Test vectors for many of the algorithms are included to provide a level
of confidence in the correctness of the implementations.

A (incomplete) TODO list is included with the package.  The NEWS file
provides a high-level overview of what has changed since the last

ASDF packaging is provided; (asdf:oos 'asdf:load-op :ironclad) should be
all you need to get started.

Comments, criticisms, additions, and optimizations are welcome at the
below email address.
