2015-07-02Revert slow non-SSE Salsa20 modification since it did not fix Android/ARM ↵Adam Ierymenko
issue. Also update Salsa20 comments and clean up a bit.
2015-07-01For @glimberg -- a *possible* fix to the alignment headaches on Android/ARM. ↵Adam Ierymenko
If this works we should find a define that can be used to enable it there since it will slow things down on non-x86 other architectures.
2014-09-16Get rid of __align stuff in Salsa20 -- not portable, does not seem to help ↵Adam Ierymenko
much on newer chips.
2014-07-26Salsa20 SSE Windows build fix -- turns out you can't be as loose with SSE ↵Adam Ierymenko
intrinsics in Visual Studio
2014-07-15SSE optimized Salsa20 -- anywhere from 20% to 50% faster than plain C versionAdam Ierymenko
2013-10-18Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet ↵Adam Ierymenko
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.
2013-07-09Several things:Adam Ierymenko
(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.
