create-hash

Node style hashes for use in the browser, with native hash functions in node. Api is the same as hashes in node:
var createHash = require('create-hash');
var hash = createHash('sha224');
hash.update('synchronous write');
hash.digest();
hash.write('write to it as a stream');
hash.end();
hash.read();
To get the JavaScript version even in node do require('create-hash/browser');
