Peter,
We have Trusted Mail (International) -- also "TMail (International)."
TMail (International) is an exportable version of PEM; it's available
for sale in Europe. The encryption in TMail (International) conforms
with the U.S. export regulations. It uses RC2 with 40 bit keys, and
the RSA key size for exchange of the data encryption key is limited to
512 bits. The integrity and signature part of TMail (International)
uses RSA (unlimited key size) and MD2/MD5, and is fully compatible
with TIS/PEM and other PEM implementations.
Our standard information on TMail (International) is attached.

TRUSTED MAIL (INTERNATIONAL)
DESCRIPTION: Trusted Mail (International) is an exportable electronic
mail system that provides privacy and security services between users
in wide-area E-Mail systems for sensitive and unclassified
information. These privacy and security services include data
integrity, originator authentication with non-repudiation (digital
signature), and (optional) message confidentiality. Trusted Mail
(International) will support the privacy and security services
required for protecting sensitive unclassified E-Mail for personal,
administrative, logistics, procurement, finance, personnel, and
medical communications.
CONFIGURATION: Trusted Mail (International) is comprised of a number
of distinct computer programs which work together to create, send,
receive and read RFC 822 compliant E-Mail messages with the following
security features: Integrity - the message received is exactly the
message sent; Originator Authentication (Digital Signature) - only the
person claiming to have sent the message could have done so; and
Confidentiality - only the intended recipient(s) can read the message.
The system processes incoming and outgoing messages for presentation
and transmission, and manages all cryptographic operations (e.g., key
management, encryption, decryption) required to support the user's
privacy and security requirements. Trusted Mail (International) uses
both symmetric and asymmetric cryptography (i.e., secret and public,
respectively) to support specific security services.
PROCESS: When a user registers with the Trusted Mail (International)
system, he/she creates a public key/private key pair. An official
binding of the public key and user's distinguished name is placed in a
publicly available "user's certificate". By electronically acquiring
each others' certificates, users can communicate using all of Trusted
Mail (International)'s security services. Because Trusted Mail
(International) is integrated with the local mail user agent (e.g.,
Rand MH), the application of security services is essentially
automatic. The originator's and recipient's only involvement with
Trusted Mail (International) is when they actually send and read the
message, respectively. At that time, the user designates which of the
privacy and security options should be applied to the message.
Trusted Mail (International) uses the RC2 algorithm with a 40 bit key
length to provide confidentiality protection of E-Mail text and the
RSA algorithm with a 512 bit key length for key management and sender
authentication.
OPERATING REQUIREMENTS: Trusted Mail (International) operates on a
wide variety of Unix platforms (including SUN/3 and Sun SparcStation
platforms running SunOS), many IBM PC/ATs and PS/2 compatible
platforms running Trusted XENIX , and other platforms running either
BSD or System V derived versions of Unix. Trusted Mail (International)
is integrated with mail User Agent (UA) software (e.g., EMACS MH and
Rand MH), which are fully compatible with SMTP-based Mail Transfer
Agents (e.g., Sendmail and MMDF). Trusted Mail (International) is
easily integrated with other UAs.
STANDARDS COMPLIANCE: Trusted Mail (International) is in compliance
with the Privacy Enhanced Mail (PEM) specifications, RFCs 1421
(Message Encipherment and Authentication Procedures), 1422
(Certificate-Based Key Management), 1423 (Algorithms, Modes and
Identifiers), 1424 (Key Certification and Related Services), and with
RFC 822 (Standard for the Format of ARPA Internet Text Messages).
Trusted Mail (International) is also compatible with the signature
services in TIS/PEM, a reference version of Privacy Enhanced Mail is
being provided to the Internet by Trusted Information Systems, Inc.
AVAILABILITY: Trusted Mail (International) is available through
Trusted Information Systems, Inc. Organizations wishing to issue
certificates to their users can become Certificate Authorities by
contacting a Policy-level Certificate Authority (PCA). PCAs are
registered with the Internet Society. RSA Data Security Inc., and
Trusted Information Systems, Inc. both operate PCAs.
