+### 上传 .class 文件到服务器的技巧
+
+使用`mc`命令来编译`jad`的反编译的代码有可能失败。可以在本地修改代码，编译好后再上传到服务器上。有的服务器不允许直接上传文件，可以使用`base64`命令来绕过。
+
+1. 在本地先转换`.class`文件为base64，再保存为result.txt
+
+    ```bash
+    base64 < Test.class > result.txt
+    ```
+
+2. 到服务器上，新建并编辑`result.txt`，复制本地的内容，粘贴再保存
+
+3. 把服务器上的 `result.txt`还原为`.class`
+
+    ```
+    base64 -d < result.txt > Test.class
+    ```
+
+4. 用md5命令计算哈希值，校验是否一致

+### Tips for uploading .class files to the server
+
+The `mc` command may fail. You can modify the code locally, compile it, and upload it to the server. Some servers do not allow direct uploading files, you can use the `base64` command to bypass.
+
+1. Convert the `.class` file to base64 first, then save it as result.txt
+
+    ```bash
+    Base64 < Test.class > result.txt
+    ```
+
+2. Login the server, create and edit `result.txt`, copy the local content, paste and save
+
+3. Restore `result.txt` on the server to `.class`
+
+    ```
+    Base64 -d < result.txt > Test.class
+    ```
+
+4. Use the md5 command to verify that the `.class` files are consistent.
