                                                       Certificate No. 1024

The National Institute of Standards and Technology, as the United States FIPS 140-2 Cryptographic Module Validation Authority;
and the Communications Security Establishment, as the Canadian FIPS 140-2 Cryptographic Module Validation Authority; hereby
validate the FIPS 140-2 testing results of the Cryptographic Module identified as:

                STS Secure for Linux by Inter-4, A Division of Sierra Nevada Corporatio
in accordance with the Derived Test Requirements for FIPS 140-2, Security Requirements for Cryptographic Modules. FIPS 140-2
specifies the security requirements that are to be satisfied by a cryptographic module utilized within a security system protecting
Sensitive Information (United States) or Protected Information (Canada) within computer and telecommunications systems
(including voice systems).

Products which use the above identified cryptographic module may be labeled as complying with the requirements of FIPS 140-2
so long as the product, throughout its life cycle, continues to use the validated version of the cryptographic module as specified in
this certificate. The validation report contains additional details concerning test results. No reliability test has been performed and
no warranty of the products by both agencies is either expressed or implied.

This certificate includes details on the scope of conformance and validation authority signatures on the reverse.

FIPS 140-2 provides four increasing, qualitative levels of security: Level 1, Level 2, Level 3, and Level 4. These levels are intended to cover
the wide range and potential applications and environments in which cryptographic modules may be employed. The security requirements
cover eleven areas related to the secure design and implementation of a cryptographic module. The scope of conformance achieved by the
cryptographic modules as tested in the product identified as:
