How to tell if SPARC T4 crypto is being used?

The SPARC T4 processor contains several new instructions that help implement cryptographic and hash algorithms. This article shows how to tell if optimized SPARC T4 hardware cryptography is being used by software on Oracle Solaris. This includes both the OpenSSL t4 engine and Solaris native crypto libraries.[Read More]

Optimizing AES modes on Solaris for Intel Westmere

Solaris 11 for x86 optimizes AES-CTR, AES-CBC, and AES-ECB modes with an innovative mixture of using 128-bit %xmm registers, AESNI instructions, processing AES and mode operations at the same time, and interleaving 4 AES blocks at a time. As a result is higher performance over using AESNI alone as a separate operation.[Read More]

Solaris AESNI OpenSSL Engine for Intel Westmere

The Solaris aesni engine for Intel Westmere uses the new Intel AESNI instructions for AES cryptography. Solaris 11 for x86 includes OpenSSL with the AESNI engine patched into OpenSSL as a built-in engine. The result is higher performance AES operations when running OpenSSL.[Read More]

Solaris IPv6 Packages

Here's some IPv6-capable packages provided for Solaris, which is certified as IPv6-ready. These packages extend IPv6-functionality for a few of the more-obscure applications I tend to use. That is: Lynx for text-only web browsing, NcFTP for file transfer, NTP for time synchronization, and TIN, a text-only NNTP news reader. I built these packages for Solaris 10 and OpenSolaris, for SPARC and X86.[Read More]
