* Split the assembly implementations of the hash functions into asm_engine.lloyd2008-11-106-39/+125
| | | | | | This still is not an ideal split, since for SHA-1 we have both SSE2 and x86/x86-64 asm. Currently we continue to punt to SSE2 if enabled, otherwise asm, since the SSE2 seems to be the fastest thing going in my tests so far.

* Several changes to HMAC_RNG, many on the basis of the paperlloyd2008-11-101-27/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boaz Barak, Shai Halevi: A model and architecture for pseudo-random generation with applications to /dev/random. ACM Conference on Computer and Communications Security 2005. which I was referred to by Hugo Krawczyk. Changes include: Remove the entropy estimation. This is a major point of Barak and Halevi's paper: the entropy we want to estimate is the condtional entropy of the collected data from the point of view of an unknown attacker. Obviously this cannot be computed! Instead HMAC_RNG simply counts each byte of sampled data as one bit of estimated entropy. Increase the reseed threshold from 2^14 to 2^20 outputs, and change the fast poll during generation from once every 1024 outputs to once every 65536 outputs (though the fast poll might not trigger that often, if output lengths are very large - however this doesn't really matter much, and with the X9.31 wrapper it does kick off exactly every 2^16 outputs). The paper also has some good arguments why it is better to reseed rarely, making sure you have collected a large amount of (hopefully) unguessable state. Remove a second HMAC PRF operation which was only being done to destroy the previous K value. Considering it has a short lifetime, seems excessive (and really hurt performance).

* Remove support for block cipher padding methods in engine. Like S2K,lloyd2008-11-1010-130/+35
| | | | | | | | | | they were not used at all outside of the core library implementations. One change is that now get_bc_pad returns a new object, instead of a pointer to a const shared padding method. This does imply a bit more dynamic memory overhead, but the modes are pretty light (stateless, for the most part), so this doesn't seem like a big deal. So modify ECB and CBC classes to add destructors to delete the padding object.
