java AES加解密

public class AesEncryptUtils {

    //加密

        byte[] encrypted = cipher.doFinal(content.getBytes());

php AES加解密

class Aes
{
    private $iv = "";//iv的长度要根据加密方式和模式来定,aes-128-cbc偏移量的是16位
    private $key = '';
    function __construct($key, $iv)
    {
        $this->key = $key;$this->iv = $iv;
    }
    public function encrypt($input){
        return base64_encode(openssl_encrypt($input, 'AES-128-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv));
    }
    public function decrypt($input){
        return openssl_decrypt(base64_decode($input), 'AES-128-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv);
    }
}
$KEY = "qxhzngy266a186ke";//密钥key
$IV  = "1ci5crnda6ojzgtr";//向量iv
$a = new Aes($KEY, $IV);
$encryptStr = $a->encrypt("hello你好");
echo $encryptStr.PHP_EOL;
echo $a->decrypt($encryptStr);

　　

 附 java md5&base64

        String str = Base64Utils.encodeToString("hello world 我".getBytes());
        System.out.println(str);
        System.out.println(new String(Base64Utils.decodeFromString(str)));    


        System.out.println(DigestUtils.md5Hex("localhost中文"));
