mq加密没问题，解密有问题

[安洋~anyang]

报严重，这个是mq解密出的问题 ，我的ali.rocketmp.first.accessKey 前后都为16 位，求大佬帮解决下，虽然是严重，项目运行没问题，但是看着就想解决

cn.aia.tools.security.AESPasswordManager decryptPassword
严重: Input length must be multiple of 16 when decrypting with padded cipher

Input length must be multiple of 16 when decrypting with padded cipher 他说输入的必须是16的倍数 参考下 https://blog.csdn.net/kzcming/article/details/80019478

对的，输入的就是16位 ，这是在本地用的mq ，是本地的无效吗？ 这个地址看了，谢谢

public void init(byte[] keyBytes) {

        // 如果密钥不足16位，那么就补足. 这个if 中的内容很重要
        int base = 16;
        if (keyBytes.length % base != 0) {
            int groups = keyBytes.length / base + (keyBytes.length % base != 0 ? 1 : 0);
            byte[] temp = new byte[groups * base];
            Arrays.fill(temp, (byte) 0);
            System.arraycopy(keyBytes, 0, temp, 0, keyBytes.length);
            keyBytes = temp;
        }
        // 初始化
        Security.addProvider(new BouncyCastleProvider());
        // 转化成JAVA的密钥格式
        key = new SecretKeySpec(keyBytes, KEY_ALGORITHM);
        try {
            // 初始化cipher
            cipher = Cipher.getInstance(algorithmStr);
        } catch (NoSuchAlgorithmException e) {
