Fast and light JavaScript SHA-256 secure hash implementation [closed]

Question

I'm looking for a hash implementation that is;

• secure (practically impossible to invert)
• fast (few ms)
• light (few KB)
• runs in the browser

Ideally a SHA-256 implementation, since it is widely used and therefore widely tested against.

Answer 1

Doing some tests suggests that forge is the fastest SHA-256 JavaScript implementation.

It is 284KB big but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256.
