WHAT IS IT?


Trusted Information Systems, Inc. (TIS), in cooperation with RSA Data
Security, Inc. (RSADSI), is pleased to provide TIS/MOSS, a reference
implementation of MIME Object Security Services (MOSS).  In order to
foster acceptance of MOSS and provide the community with a usable,
working version of this technology, TIS/MOSS is being made available for
broad use on the following basis.

TIS/MOSS is distributed in source code form, with all modules written in
the C programming language.  It runs on many UNIX derived platforms.

TIS/MOSS requires RSAREF, a cryptographic toolkit distributed by RSADSI.
TIS/MOSS makes use of undocumented features of RSAREF.  RSADSI has given
permission for users of TIS/MOSS to use these features, subject to the
terms and conditions of both the TIS/MOSS and RSAREF licenses, as
distributed with each software package.

TIS/MOSS is a product of Trusted Information Systems, Inc.

For instructions on how to install TIS/MOSS, please see the file INSTALL
in the same directory as this file.


WHAT YOU MAY (AND MAY NOT) DO WITH TIS/MOSS

The license in the file license.txt (in the same directory as this file)
gives specific legal terms and conditions.  The following is a layman's
interpretation, for information only and with no legal weight.

1. TIS/MOSS is for sending and receiving MOSS-based email.  It is not to
   be utilized in any form or for any purpose other than to send and
   receive MOSS-based mail.  Other than the restriction that the code is
   to be used for MOSS-based mail, there is no limitation on the
   purposes for which it may be employed.  It is specifically intended
   that TIS/MOSS be used to protect the full range of email
   transactions.  In particular, users are encouraged to use it for
   research, education, personal, and internal commercial transactions.

2. You may distribute TIS/MOSS freely within your organization under the
   same terms and conditions as the TIS/MOSS license.  You may not
   distribute TIS/MOSS outside of your organization.  This restriction
   is intended to avoid inclusion of TIS/MOSS as part of a commercial
   offering.  TIS/MOSS and its documentation may not be incorporated
   into any program, product, or service that is sold or for which any
   revenue or other consideration is received.

3. TIS/MOSS may be used with certificates issued within the Internet
   certificate hierarchy, with certificates outside of this hierarchy,
   or with bare public keys.  In any case, users are responsible for the
   trust invested in any certificate or key.

4. The certificate and key issuing facilities of TIS/MOSS may be used to
   issue certificates and keys within your own organization.  You may
   not issue certificates or keys to persons or entities outside of your
   organization.

5. You may modify TIS/MOSS as required to port it to other operating
   systems and compilers.  Any such modification is subject to the terms
   of this license.  TIS requests, but does not require, that you give
   TIS a copy of the changes.

6. You may not send TIS/MOSS outside the United States or Canada, nor
   may you give it 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.)

7. As with any system involving cryptography, there are certain risks
   which are inherent.  Users are particularly cautioned that the
   security of their email depends in part on unpredictability of the
   keys and on the protection of private keys.  Both of these matters
   are dependent on the execution environment, which is outside the
   control of this code.  TIS assumes no liability for any flaws in the
   security of this system.  System Administrators and Users are
   referred to the documentation for further guidance.


USERS GROUP

A TIS/MOSS electronic users group mailing list has been created for
discussions related to the use of Trusted Information Systems' MOSS
implementation.  Please send contributions to the list proper to
"tismoss-users@tis.com".  Administrivia, e.g., additions to or deletions
from the list, should be sent to "tismoss-users-request@tis.com".

TIS/MOSS technical questions, license issues, bug reports, etc., should
be addressed "tismoss-support@tis.com".


DEVELOPERS GROUP

A PEM/MOSS Developers mailing list has been created for discussions
related to the development and deployment of Privacy Enhanced Mail and
Mime Object Security Services systems.  Please send contributions to the
list proper to "pem-dev@tis.com".  Administrivia, e.g., additions to or
deletions from the list, should be sent to "pem-dev-request@tis.com".


CERTIFICATE REGISTRATION

Users or groups who wish to use TIS/MOSS with certificates that are
part of the Internet certificate hierarchy should contact the
appropriate certification authority.  Organizations wishing to issue
certificates to their users should contact a Policy Certification
Authority (PCA).  Both TIS and RSADSI operate PCAs.
