大家都知道AES加密解密又称为对称加密解密，详细的介绍在百度百科以及其他大佬的博客上有很多讲解，这里我就不在重复基本知识了，只做js和java两端加密解密操作对比。(试用范围：WEB开发登陆加密解密操作、APP重要信息上传、APP蓝牙通信等)。
一、java和js使用AES-ECB加密解密对比(最后的js库包含有aes所有的加解密 )
的充方式 PKCS5Padding，有一位大佬已经写了的，就直接分享大佬连接吧，连接。
填充方式 nopadding，参照大佬的思路，我的代码

};有人可能会说，我这边用明文是“1111111111111111”，你是把“1”当作字符，十六进制则是0x31，如果我写的是"31313131313131313131313131313131"，每个31是十六进制数呢？
思路区别：
当我使用的是字符"1"时，加密数据、key等使用如下形式进行格式转换操作 var key = CryptoJS.enc.Utf8.parse(1111111111111111);；
当我使用"31"表示十六进制0x31时，使用以下方式转换：var key = CryptoJS.enc.Hex.parse("31313131313131313131313131313131")；
二、AES-CCM加密解密操作
java部分：
1、我是使用的maven作为java环境的创建，首先需要导入加密的jar文件，pom.xml中需要添加
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.58</version>
</dependency>2、编写java代码：

byte[] header = { '1','2','3','4','5','6','7','8','9','a','b','c','d','e' };
try {

if(!wheterDecrypt) {
//加密
cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, parameterSpec);
}else {

cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, parameterSpec);
}
cipher.updateAAD(header);
bs = cipher.doFinal(context);
