android - android 6.0 javax.crypto.BadPaddingException：错误：1e000065：密码函数：OPENSSL_internal：BAD_DECRYPT

Question

此代码在 android 6.0 之前运行良好，但如果加密文件大小小于约 1k 字节，则在 6.0 上会出错。

public static byte[] decode(byte[] decrypteSrcBuffer) throws Exception {
    Key deskey = null;
    DESedeKeySpec spec = new DESedeKeySpec(mKeyBytes);
    SecretKeyFactory keyfactory = SecretKeyFactory.getInstance("desede");
    deskey = keyfactory.generateSecret(spec);
    Cipher cipher = Cipher.getInstance("desede/CBC/PKCS5Padding");
    IvParameterSpec ips = new IvParameterSpec(iv.getBytes());
    cipher.init(Cipher.DECRYPT_MODE, deskey, ips);
    byte[] decryptData = cipher.doFinal(decrypteSrcBuffer);

    return decryptData;
}

错误信息：
