Safari gives incorrect output for an asm.js compiled hashing library (js-scrypt). It's speculated that the issue has to do with low level string formatting / conversion, that isn't being properly implemented in Safari.

On Subrosa.io, users cannot sign into accounts created by non-Safari browsers on Safari, and vice versa.

This isn't an issue with the library, but rather with JavaScriptCore.
