hash-wasm

Noted, will add that. Last time I tried https://github.com/Daninet/hash-wasm edit: I focus on browsers, that's wasm but not for browser envs. ---- https://theultdev.github.io/web-sha256-benchmark https://github.com/TheUltDev/web-sha256-benchmark seems it is chrome wasm that is slow. asmjs is about the same speed in chrome and firefox (with asm optimizations still enabled) but wasm is slow as hell in chrome, asm still better. side note: someone mentioned native crypto.subtle, but that doesn't have incremental hashing so can't use it for large files. however I do use it in practice for smaller files.

Still, you can archive significant speed-ups with WebAssembly at some use cases. For example, I have a hash function library (https://github.com/Daninet/hash-wasm) where I was able to archive 14x speedup at SHA-1 and 5x speedup at MD5 compared to the best JS implementations. You can run the benchmarks on your computer here: https://daninet.github.io/hash-wasm-benchmark/
