    Use sha.js instead of crypto-browserify
    
    This still passes all the tests and makes the library about 14KB
    minified and Gzipped (including all dependencies) rather than about
    200KB minified and Gzipped.  Without this change, the library is
    practically unusable for anyone who doesn’t expect to need a
    significant proportion of the rest of crypto-browserify.
