I can't know what you maybe forwarded or not. So I'm sorry if something here (or maybe even everything) is already known. I already talked (a littlebit *looks into the sky*) with Solar direclty. Using OpenSSL could speed up John if a crypto-accelerator is present and if the OpenSSL-Version supports these Cards. I'm using OpenBSD wich supports such functions for about 2 years now (but the official OpenSSL should provide it now also). Offen you'll find just some realy lame Chips on VPN-Hardware but if you don#t buy such a Cisco-Junk solution you could also get such a device here (not sold yet): http://www.soekris.com/vpn1461.htm This card could, depends to the algorithm, do e.g. up to 920Mbps of DES. During OpenBSDs OpenSSL it is possible to include serval cards e.g. in one Computer. This card is realy new but e.g. this card here http://www.soekris.com/vpn1401.htm is currently avaiable. I thought about this idea because i've some Pentium2-Motherboards here. If I would e.g. buy 5 Crypto-Cards they would work simultaniusly (like SMP) on OpenBSD. The algorithm isn't the best Theo told me but it should work. because these cards are cheap AND fast it would be logical to "abuse" these cards to speed up john a littlebit. OpenBSD supports a lot Crypto-Cards (not Just Soekris Boards but Soekris provides OpenSource so they're a prefereable brand) http://www.openbsd.org/cgi-bin/man.cgi?query=hifn&arch=i386&sektion=4 OpenBSD on e.g. a new Via Epia Motherboard would enable John to crack AES with nearly 20Gbit/s because of the VIa "Pad-Lock"-Engine wich is also fully supported by OpenBSD. I'm just talking about OpenBSD because I don't use LINUX so I don't know about the status there and also I don#t know about the support of these cards. But because the last OpenSSL-Changes (supporting Such cards went into the official OpenSSL-Version) this could be interesting even for Linux-Users. Kind regards, Sebastian -- Don't buy anything from YeongYang. Their Computercases are expensiv, they WTX-powersuplies start burning and their support refuse any RMA even there's still some warenty.
