Padlock support is not backported into Centos, nor upstream.
Thanks for the heads-up!
2.6.11 kernel it has been accepted into the source tree (only AES), so we can expect it in RHEL/Centos5?!? For SHA1 and SHA256 every kernel must be patched.
$ rpm2cpio kernel-2.6.18-1.2747.el5.i686.rpm | cpio -t | grep 'padlock' ./lib/modules/2.6.18-1.2747.el5/kernel/drivers/crypto/padlock.ko
Looking at the symbols this seems to implement AES offloading.
Interesting reading http://www.logix.cz/michal/doc/article.xp/padlock-en
Very interesting indeed.
