Has anyone tried one? Any noticeable performance improvements for AES-256 operations?
I guess the bigger question is whether Bacula will call in methods of OpenSSL engine(3). E.g., Apache mod_ssl needs to have an Engine type explicitly defined in the config: See: http://httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslcryptodevice Also see: ssl_engine_config.c in httpd-2.2.11/modules/ssl in Apache We don't appear to be calling engine(3) API at all: ..work/bacula-2.4.4$ grep -ir engine src/lib/*{crypt,ssl}* ..work/bacula-2.4.4$ I'm assuming that each OpenSSL linked userland application must explicitly define engine(3) calls to take advantage of HW Crypto Accel/Offload then (compared to kernel services such as geom(4)/geli(8) and ipsec(4) on FreeBSD can rely on the kernel OpenCrypto(9) transparently) ? -- Brian A.
