It is a meta package and lets you to use
js-sha3 with the same interface on your choice of deployment. It uses
browserify-sha3 to do the mapping for you.
There's no speed loss, it is as thin as it can get (but there is some twiddling in
package.json to select the right package for your environment):
moduleexports = SHA3Hash
const keccak =var hash = // uses 512 bits by defaulthashhashhash // binary outputhash // hex output
NOTE: This library supports the Keccak padding only - and not the final SHA3 padding.
