RSA Data Security, Inc., and Trusted Information Systems, Inc., are
pleased to provide TIS/PEM, a reference implementation of Privacy
Enhanced Mail (PEM).  In order to foster acceptance of PEM and provide
the community with a usable, working version of this technology,
TIS/PEM is being made available for broad use on the following basis.

TIS/PEM is distributed in source code form, with all modules written
in the C programming language.  It runs on many UNIX derived
platforms, including BSD, System V, NeXT, and ULTRIX.  It is currently
integrated with the following user interfaces: Version 6.8.3 of the
Rand MH Message Handling system and XMH.  It's modularity should make
it easy to integrate into other mail user agents.

TIS/PEM is a product of Trusted Information Systems, Inc. and is made
available with the cooperation of RSA Data Security, Inc.

TIS/PEM's distribution and use are governed by a license, a copy of
which is included in this directory (LICENSE) and a copy of which is
included with the distribution. 

TIS/PEM cannot be distributed outside the United States or Canada, nor
can it be distributed to anyone who is not a U.S. or Canadian citizen
and does not have a U.S. "green card."  (These are U.S. State and
Commerce Department requirements because RSA and DES are
export-controlled technologies.)

If you meet the country/citizenship requirements and agree to the
license, you can obtain the current version of TIS/PEM (7.0) by
getting the file

  dist/pem-9a96ee/p-7.0.tar.Z

  (full path is /pub/PEM/dist/pem-9a96ee/p-7.0.tar.Z)

The dist directory is a blind directory (you can't see into it) and
the subdirectory (pem-XXXXXX) changes periodically.  The name will be
valid for at least ten minutes after you retrieve this file.  If you
cannot get the file, read the latest README file to get the new
directory name.

If you specify a path (directories as well as file name) for the
remote file name when you issue your FTP get command, specify a local
file name as well.  Otherwise, your ftp client may try to save the
file using the same path that you specified for the remote file name
and, since it probably doesn't exist on your system, you'll get a "No
such file or directory" message.

p-7.0.tar.Z is a compressed tar file that must be transferred in
binary mode.  Uncompressing and untarring p-7.0.tar.Z will produce a
source tree rooted at pem-7.0.  Read the INSTALL file to get started.

MH is no longer distributed with TIS/PEM.  If you don't already have a
copy of MH version 6.8.3, a compressed tar file can be found on this
server in /pub/PEM/other/mh-6.8.3.tar.Z.
