maybe. yes in that network hardware often provides hardware accelerated crypto primitives that can be utilized by Tor to accelerate the CPU bound aspects of relaying a large amount of traffic. no since hardware acceleration is poorly supported in OpenSSL let alone via direct offload in Tor itself. the latter is necessary to truly take advance of hardware acceleration for large chunks of CTR mode or Montgomery multiplication given shortcomings in the OpenSSL API's used by Tor. if you have a hardware entropy device and a good userspace entropy daemon / mixer this is always useful to Tor and OpenSSL in general. this is manged outside of Tor or OpenSSL by administrator however. as for particular hardware acceleration support the archives of this list provide some details. best regards, *********************************************************************** To unsubscribe, send an e-mail to [email protected] with unsubscribe or-talk in the body. http://archives.seul.org/or/talk/
