Adam Ierymenko 8d2e20ede6 Get rid of __align stuff in Salsa20 -- not portable, does not seem to help much on newer chips. 12 years ago
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
