a8ced184dc Some code cleanup and make sure any type punning is guarded with ZT_NO_TYPE_PUNNING. 2017-04-20 09:33:35 -07:00

7a94f63058 Back out NaCl since the old one with xmm6 salsa2012 does not support multi-block use and the new one is slower. 2017-04-17 17:54:12 -07:00

df48738ac9 Enable use of NaCl for faster X64 Salsa20 implementations. Also include binary for OSX for easy build. Blazingly fast. 2017-04-17 16:43:03 -07:00

43182f8f57 Docs, code cleanup, and protect the extra new fields of HELLO with encryption as a precaution. 2017-02-05 16:19:03 -08:00

0c498556d5 Unroll Salsa20 fully for a little more speed (non-SSE now almost as fast as SSE) 2015-10-09 09:39:27 -07:00

160278c489 Little bit of reorg in Salsa20 which seems to speed things up very slightly. 2015-10-08 17:42:53 -07:00

789046ca57 Speed up Salsa20 just a bit. 2015-09-30 14:35:05 -07:00

a297e4a5bf Add build def ZT_NO_TYPE_PUNNING, which when defined disables type punning code that might cause unaligned access errors on architectures that care (e.g. Android/ARM) 2015-07-08 09:12:51 -07:00

f19c3c51d3 Revert slow non-SSE Salsa20 modification since it did not fix Android/ARM issue. Also update Salsa20 comments and clean up a bit. 2015-07-02 09:00:00 -07:00

7c9949eea3 For @glimberg -- a *possible* fix to the alignment headaches on Android/ARM. 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. 2015-07-01 12:29:23 -07:00

8d2e20ede6 Get rid of __align stuff in Salsa20 -- not portable, does not seem to help much on newer chips. 2014-09-16 08:53:18 -07:00

f2d372545a Salsa20 SSE Windows build fix -- turns out you can't be as loose with SSE intrinsics in Visual Studio 2014-07-26 20:07:38 -07:00

12692c551e SSE optimized Salsa20 -- anywhere from 20% to 50% faster than plain C version 2014-07-15 17:56:09 -07:00

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. 2013-10-18 17:39:48 -04:00

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.
