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, ConnectSecure, and Server. However, only the algorithms provided by the fipscanister object in the library are used by Tectia Client, ConnectSecure, and Server. The OpenSSL FIPS-certified cryptographic library is used to provide the following classes of functions:

Table 3.1. APIs used from the OpenSSL library

API	Description	Functions from OpenSSL
Random numbers	FIPS-approved AES PRNG based on ANSI X9.32 is used from the OpenSSL library.	FIPS_rand_*
AES ciphers	Variants: ecb, cbc, cfb, ofb, ctr	AES_*
DES ciphers	Variants: ecb, cbc, cfb, ofb	DES_*
3DES ciphers	Variants: ecb, cbc, cfb, ofb	DES_*
Math library	Bignum math library used by OpenSSL.	BN_*
Diffie Hellman		DH_*
Hash functions	Variants: sha1, sha-224, sha-256, sha-384, sha-512	SHA1_, SHA256_, SHA512_*
Public Key	Variants: rsa and dsa	RSA_, DSA_

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

The FIPS 140-2 Cryptographic Library is available on the operating systems supported by Tectia, except 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.
