The emscripten module from C SHA256 code is much faster than the pure ES6 SHA256 code. But the emxcripten module required async initialization and explicit cleanup calls. In this article, Implement SHA256 in WebAssembly directly (with no emscripten).

Note about imprementing major cryptographic Hash functions(SHA256, SHA512, SHA1, MD5, RIPEMD169) with standard C11. Entire codes in gist are:

These hash are similar algorithms. Once writing one of them, writing others would be easy.

For comparing the performance of WebAssembly runtimes with others, I published on-browser programs with the same algorithm as “plain ES6”, “asm.js” and “WebAssembly” without emscripten.
