While it obviously makes no sense to use client-side crypto for verification, there can still be use for things like MD5 and SHA-1 on the client side. I have a script that does SHA-1 hashing for images fetched via XHR, for example (which is used for reverse image searching purposes).

Seeing this, I guess I should do some benchmarking and see whether it gives better speeds than my current implementation (and also look for any other options and test those too).
