OpenSSH and T2

Following from the last entry about recent enhancements to SunSSH to enable it to take advantage of the UltraSPARC T2 cryptographic accelerators, for those who use OpenSSH, its also possible to leverage the T2 cryptographic accelerators. One simple way to achieve this, without modifying OpenSSH itself, is just to use a version of OpenSSL that has been modified to take advantage of the HW crypto; for the standard aes-128-cbc operating mode, the simplest way to achieve this is to modify aes_cbc.c to call libpkcs11. Its about a 10 line modification and can be applied to any version of OpenSSL. I will post the required code later today here.
