\brief C++ wrapper for the CRYPTPLUG library API.
This CRYPTPLUG wrapper implementation is based on cryptplug.h by
Karl-Heinz Zimmer which is based on 'The Aegypten Plugin API' as
specified by Matthias Kalle Dalheimer, Klaraelvdalens Datakonsult AB,
see file mua-integration.sgml located on Aegypten CVS:
http://www.gnupg.org/aegypten/development.en.html
purpose: Wrap up all Aegypten Plugin API functions in one C++ class
for usage by KDE programs, e.g. KMail (or KMime, resp.)
CRYPTPLUG is an independent cryptography plug-in API
developed for Sphinx-enabeling KMail and Mutt.
CRYPTPLUG was designed for the Aegypten project, but it may
be used by 3rd party developers as well to design pluggable
crypto backends for the above mentioned MUAs.
\note All string parameters appearing in this API are to be
interpreted as UTF-8 encoded.
\see cryptplugwrapper.h
