FIPS-Certified Cryptographic Library

Tectia Client, ConnectSecure, and Server can be operated in FIPS mode, using a version of the cryptographic library that has been certified according to the Federal Information Processing Standard (FIPS) 140-2.

The full OpenSSL cryptographic library is distributed with Tectia Client. However, only the algorithms provided by the fipscanister object module in the library are used by Tectia Client. The OpenSSL FIPS-certified cryptographic library is used to provide the classes of functions listed in the following tables.

The functions from the OpenSSL library version 1.0.2a used on Linux, Windows, Solaris and HP-UX Itanium (IA-64) are listed in Table 3.1. On these platforms, the fipscanister object module version 2.0.9 is used.

The functions from the OpenSSL library version 0.9.8 used on HP-UX PA-RISC and IBM AIX are listed in Table 3.2. On these platforms, the fipscanister object module version 1.2 is used.

The FIPS 140-2 Cryptographic Library is not available for Tectia Server for Linux on IBM System z and Tectia Server for IBM z/OS which do not support OpenSSL FIPS-certified cryptographic libraries. They support hardware acceleration on FIPS cryptographic operations.

No certificate functions are used from the OpenSSL library. Tectia provides its own certificate libraries.
