node.js哈希字符串？

看看crypto.createHash（algorithm）

var filename = process.argv[2];var crypto = require('crypto');var fs = require('fs');var md5sum = crypto.createHash('md5');var s = fs.ReadStream(filename);s.on('data', function(d) {  md5sum.update(d);});s.on('end', function() {  var d = md5sum.digest('hex');  console.log(d + '  ' + filename);});
