This security enhancement is new in the Solaris 10 6/06 release.
A kernel-level SSL proxy server has been added in this release. The proxy simplifies and accelerates the SSL/TLS protocol implementation by pushing handshake and records processing to the kernel. The proxy supports the most commonly used cipher suites. You can configure applications, such as web servers, to offload the handling of the SSL operations with those cipher suites to the proxy, and seamlessly fall back to their existing user-level SSL library for the others.
