Adam Ierymenko	f2d372545a	Salsa20 SSE Windows build fix -- turns out you can't be as loose with SSE intrinsics in Visual Studio	12 years ago
Adam Ierymenko	12692c551e	SSE optimized Salsa20 -- anywhere from 20% to 50% faster than plain C version	12 years ago
Adam Ierymenko	8c9b73f67b	Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance.	13 years ago
Adam Ierymenko	ef3e319c64	Several things: ... (1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed. (2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture. (3) Add -fstack-protect to Makefile to bounds check stack variables.	13 years ago
