The features provided by this software in this release are as follows:

• Acceleration of cryptographic operations using the “lookaside” model, via the 

Cryptographic API. For more details, see 

— Symmetric cryptographic operations supported include ciphers [AES, 3DES, 

DES, (A)RC4] and message digest/hash for authentication (MD5, SHA-1, SHA-2 

as well as HMAC).

— Asymmetric (public key) cryptographic operations such as modular 

exponentiation to support RSA, Diffie-Hellman, DSA.

— “True” random number generation.

This allows for cryptographic protocols such as IPSec and SSL to offload compute-

intensive cryptographic operations, freeing up the IA core to execute higher-value 

application code.

• Software is provided which adapts between the Cryptographic API and that 

expected by the industry-standard OpenBSD Cryptographic Framework (OCF). This 

OCF “shim” allows applications — such as Openswan* and OpenSSL* —which are 

written to use the OCF APIs, to seamlessly take advantage of the cryptographic 

acceleration engine. 
Note: The EP80579 security software release package version 1.0.3 does not 

support OpenBSD/FreeBSD Cryptographic Framework (OCF), OCF-Linux, or 

any open source projects such as Openswan*, OpenSSL*, or Racoon*. If 

your application requires OCF, you must use security software package 

version 1.0.2 which includes shim software to enable OCF support.
