  • nodejs与javascript中的aes加密

     
    // var CryptoJS = require("crypto-js");
    // var key = CryptoJS.enc.Utf8.parse("8NONwyJtHesysWpM");
    var crypto = require('crypto');
    var key = new Buffer('7y05R9qwKaIKgIHh4vAw19X1zuknR21Y', 'binary');
    var iv = "";
    var cryto_aes = module.exports = {};
     
    //加密
    cryto_aes.Encrypt = function(data){
     
      iv = iv || "";
      var clearEncoding = 'utf8';
      var cipherEncoding = 'base64';
      var cipherChunks = [];
      var cipher = crypto.createCipheriv('aes-256-ecb', key, iv);
      cipher.setAutoPadding(true);
      cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));
      cipherChunks.push(cipher.final(cipherEncoding));
      return cipherChunks.join('');
    }
    //解密
    cryto_aes.Decrypt = function(data){
     
      if (!data) {
        return "";
      }
      iv = iv || "";
      var clearEncoding = 'utf8';
      var cipherEncoding = 'base64';
      var cipherChunks = [];
      var decipher = crypto.createDecipheriv('aes-256-ecb', key, iv);
      decipher.setAutoPadding(true);
      cipherChunks.push(decipher.update(data, cipherEncoding, clearEncoding));
      cipherChunks.push(decipher.final(clearEncoding));
      return cipherChunks.join('');
     
    }

    参照上述方法时注意 iv 和 key的设置  可能会报Invalid IV length 错  解决方法 就是 设置成我粘贴的代码中的格式。
