Hello,

I've been playing around with the Pycrypto AES implementation and am quite
impressed. One question however, regarding CFB mode: how come it's so slow?
It's 12 times slower than any of the other modes according to by benchmarks.
Looking at the source, I can see that the implementation is 8-bit CFB but
still, according to AC, p.209, CFB's speed should be the same as the block
cipher. What's going on?

Thanks.
