<S> GENERAL
<Q> What is GnuPG?
[H a href=[$hGPGHTTP]]GnuPG[H /a] stands for GNU Privacy Guard and
is GNU's tool for secure communication and data storage. It can be
used to encrypt data and to create digital signatures. It includes
an advanced key management facility and is compliant with the
proposed OpenPGP Internet standard as described in [H a href=http://www.rfc-editor.org/]RFC 2440[H/a].
As such, it is aimed to be compatible with PGP from PGP Corp. and
other OpenPGP tools
<Q> Is GnuPG compatible with PGP?
In general, yes. GnuPG and newer PGP releases should be implementing
the OpenPGP standard. But there are some interoperability problems.
See question <Rcompat> for details.
<Q> Is GnuPG free to use for personal or commercial use?
Yes. GnuPG is part of the GNU family of tools and applications built
and provided in accordance with the Free Software Foundation (FSF)
General Public License (GPL). Therefore the software is free to copy,
use, modify and distribute in accordance with that license. Please
