Encryption and decryption for https could benefit quite a bit, I would think.

Except Intel already put in specific instructions for that.

I was surprised to discover that GPUs can accelerate SQLite http://pbbakkum.com/db/ and routing http://shader.kaist.edu/packetshader/ (although you're probably better off using an NP for routing).

Now that IS interesting. Thanks for the links!

Can encryption be parallelized? With block cipher chaining modes like CFB, each block depends on the previous block. You can parallelize encryption if you use ECB but that's known to be insecure.

Individual streams aren't parallelizable, but if you have many streams open at once you could hypothetically process them together in parallel instead of separately in parallel as it is with a CPU.

Also, there are block modes that are seekable and thus could be parallelized if you had a big enough backlog, CTR mode in particular, but parallelizing individual streams is not likely to reap big enough rewards to justify the complexity.
