java输出不一样

Question

var get = function(a) {
    var b = CryptoJS.MD5('contentWindowHig');
    var c = CryptoJS.enc.Utf8.parse(b);
    var d = CryptoJS.enc.Utf8.parse('contentDocuments');
    var e = CryptoJS.AES.encrypt(a, c, {
        iv: d,
        mode: CryptoJS.mode.CBC
        pad: CryptoJS.pad.ZeroPadding
    });
    return e.toString()
}
}

太简单了。

js转换为Java

// var b = CryptoJS.MD5('contentWindowHig');

String b = org.apache.commons.codec.digest.DigestUtils.md5Hex("contentWindowHig");

// var c = CryptoJS.enc.Utf8.parse(b);

byte[] c = b.getByte("UTF-8");

// var d = CryptoJS.enc.Utf8.parse('contentDocuments');

byte[] d = "contentDocuments".getByte("UTF-8");

  /* var e = CryptoJS.AES.encrypt(a, c, {
      iv: d,
      mode: CryptoJS.mode.CBC
      pad: CryptoJS.pad.ZeroPadding
  }); 
  return e.toString()
  */


Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(c, "AES"), new IvParameterSpec(d));

Base64.getEncoder().encodeToString(cipher.doFinal(a.getBytes("utf-8")));

a是加密str

cryptoJS aes编码数据与java代码不匹配

java输出不一样
