Hey Kid, Need a Crypto Card?

I am currently in possession of a large number of things I really don't need to have around, including, because I'm that kind of weirdo, a couple of PCI crypto cards - an AEP2000 (donated to me by AEP so I could write drivers for botan for it) and a Hifn 7811 (an ebay impulse buy).

The AEP2000 card is basically a modular exponentiator engine - the 2000 in the name refers to the number 1024-bit private key RSA operations it can perform per second (so, 4000 512-bit exponentations per second (they were counting CRT optimizations when they made the model numbers)), and you can use moduli up to 2048 bits. In testing I found that it could indeed reach 2000 ops per second in practice. There are open source Linux drivers available for this card, but nobody has ever updated them for anything past a 2.4 kernel, and it doesn't seem like they are SMP safe either. Since I don't have the time (or inclination) to update and fix them, I would rather give the card away to an open source developer who can make use of it somehow.

The Hifn 7811 offers symmetric encryption (DES, RC4, possibly AES?), MD5 and SHA-1 hashing, and a hardware PRNG. It is similiar, but not identical, to the Soekris vpn1401. There are drivers for this card included in the Linux kernel, but only 32 bit kernels are supported (I asked Evgeniy Polyakov, the author of the driver about this, and he indicated it is a hardware limitation). The only 32-bit machines I have left are laptops and netbooks, which obviously can't really take a PCI card, leaving me with a card with no place to go.

If you would like to play with either (or both) of these cards, drop me an email and let me know. I would likely give preference to someone who will be using them to support an open source project, but feel free to contact me even if this is not the case; mostly I'd like to give them a good home where they will be doing something useful.
