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：
package LinkpowerLock.AES.CCM;
import java.security.InvalidAlgorithmParameterException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import java.util.Arrays;
import javax.crypto.BadPaddingException;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.spec.GCMParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import LinkpowerLock.AES.ECB.ECBHardTest;
public class AesCcm {
/**

* @param wheterDecrypt 是否执行解密
* @return byte[]
*/
public static byte[] whetherDecrypt(byte[] context,byte[] nonce,byte[] keyBytes,boolean wheterDecrypt) {
Security.addProvider(new BouncyCastleProvider());
//避免出现java.lang.IllegalArgumentException: iv == null
if(nonce == null) {
return null;
}
byte[] bs = null;
//32 mac
GCMParameterSpec parameterSpec = new GCMParameterSpec(32, nonce);
byte[] header = { '1','2','3','4','5','6','7','8','9','a','b','c','d','e' };
try {
Cipher cipher = Cipher.getInstance("AES/CCM/NoPadding");
SecretKeySpec secretKeySpec = new SecretKeySpec(keyBytes, "AES");
if(!wheterDecrypt) {
//加密
cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, parameterSpec);
}else {
//解密
cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, parameterSpec);
}
cipher.updateAAD(header);
bs = cipher.doFinal(context);
} catch (InvalidKeyException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return bs;
} catch (InvalidAlgorithmParameterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalBlockSizeException e) {
// TODO Auto-generated catch block

} catch (BadPaddingException e) {

return bs;
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchPaddingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return bs;
}
public static void main(String[] args) {
byte[] content = {0x01,0x6e,0x04,0x08,0x08,0x06,0x06,0x00,0x00
,0x00,0x00,0x00,0x00,0x00,0x00,0x00};
byte[] key = {0x39,0x50,0x41,0x4e,0x30,0x2e,0x33,0x30,0x36,0x22
,0x2c,0x22,0x56,0x65,0x6e,0x31};
byte[] nonce = {(byte) 0xf1,(byte) 0x8e,0x08,(byte) 0x89,0x1a,0x38,0x5f,0x7f,0x0d,0x5d,0x5a,0x43};
byte[] encryptVal = whetherDecrypt(content,nonce,key,false);
//System.out.println(Arrays.toString(encryptVal));
System.out.println(ECBHardTest.parseByte2HexStr(encryptVal));
}
}
