SPARC T4 Digest and Crypto Optimizations in Solaris 11.1
In a previous
article I mentioned SPARC T4 processor optimizations added to
OpenSSL. The SPARC T4 processor supports new instructions to
assist AES, RSA, SHA, and other crypto and hash algorithms. These
optimizations were added in Oracle Solaris 11 using a new OpenSSL
"t4...

Optimizing Solaris 11 SHA-1 on Intel Processors
SHA-1 is a "hash" or "digest" operation that produces a 160 bit
(20 byte) checksum value on arbitrary data, such as a file.
It is intended to uniquely identify text and to verify it hasn't
been modified.
Max Locktyukhin and others at Intel have improved the
performance of the...

Optimizing AES modes on Solaris for Intel Westmere
Optimizing AES modes on Solaris for Intel Westmere
Review
AES is a strong method of symmetric (secret-key)
encryption.
It is a U.S. FIPS-approved cryptographic algorithm (FIPS 197)
that operates on 16-byte blocks.
AES has been available since 2001 and is widely used.
However, AES by...

to the red Oracle sign.
However, the name Sun still lives on as a
trademark of Oracle for our powerful line of SPARC and X86 servers,
backed by thousands of engineers, technical,...
