And for BBSers... PGP is available from the Turning Point. Look in
the SDN file area (Software Distribution Network).  It floated
in last week over the FidoNet filebone. The file is compressed
using PAK and it includes sources.  

It's free.  If you have any problems find it or uncompressing
it just leave mail for Tom Parish...I'll help.

I the Library there are two postcript files that are rather 
complete backgrounders on Cryptography. Here is how it 
begins...

This new document discusses in detail many aspects of current cryptography,
whether theoretical, practical, legal or commercial. It is a broad guide to
the state of cryptography today, and includes both introductory and advanced
topics. Although not a technical document, this FAQ gives extensive 
bibliographic references to the technical literature for all major areas
of cryptography. The FAQ will be continually edited to reflect new
developments; it is thus an important guide for those who wish to be kept
up to date on the latest legal and political controversies as well as the
latest achievements in factoring.
 
`Frequently Asked Questions' is available via anonymous ftp from rsa.com,
in the pub/faq directory. It is available in both postscript and LaTeX
formats. Those without ftp capability can obtain a hard copy by sending
