-ARM NEON (32-bit) ASM implementation of Salsa20/12
-======
-
-This is from [supercop](http://bench.cr.yp.to/supercop.html) and was originally written by Daniel J. Bernstein. Code is in the public domain like the rest of Salsa20. It's much faster than the naive implementation.
-
-It's included automatically in 32-bit Linux ARM builds. It likely will not work on 64-bit ARM, so it'll need to be ported at least. That will unfortunately keep it out of mobile versions for now since those are all going 64-bit.

-Blazingly fast X64 ASM implementation of Salsa20/12
-======
-
-This is ripped from the [cnacl](https://github.com/cjdelisle/cnacl) source. The actual code is by Danial J. Bernstein and is in the public domain.
-
-This is included on Linux and Mac 64-bit builds and is significantly faster than the SSE intrinsics or C versions. It's used for packet encode/decode only since its use differs a bit from the regular Salsa20 C++ class. Specifically it lacks the ability to be called on multiple blocks, preferring instead to take a key and a single stream to encrypt and that's it.
