I think add support of AES accelerate to OpenSSL is much mor important.

Now, this feature comes from pure Linux Kernel 2.6.33 released by Linus Torvalds as provided by the link below : http://kernelnewbies.org/Linux_2_6_33#head-12719ade57a6c0dd4ea893cfb21e07451 2419ca7 In the above link, we have a new feature pertaining to cryptography is mentioned as pasted below: ghash: Add PCLMULQDQ accelerated implementation (commit) Now, the code "PCLMULQDQ" corrosponds to the new instruction set introduced by Intel Xeon (westmere). Redhat's kernel versions are a little different from the pure kernel. Redhat claims that the current 5.5 release kernel consists of most of the features of 2.6.34 kernel. However, the information which features are actually backported and which are not is not present in Redhat website. Thus I would like to know whether this feature is backported from pure Linux Kernel to RHEL 5.5 or not. Additionally I need another information, whether AES-NI alogrithm is supported in RHEL 5.5. Thanks in advance. Regards, Ghanashyam Hegde
