-Previous code is archived in [`windows-archived2`](https://notabug.org/doublesine/navicat-keygen/src/windows-archived2) branch for the reason that Navicat has come to version 16.x.x which I think should be a milestone and I decide to obsolete previous code and rewrite new one.

+
+> You can download [Screen recoding](image/Screen_recording.mp4) for references.
+
+1. Switch to the path you extracted the installation package. Run Navicat, for initialization:
+
+   ```console
+   $ cd ~/navicat121_premium_en_x64
+   $ ./start_navicat
+   ```
+
+   When running for the first time, you will be prompted with the following two windows, click "Cancel" to:

+   ![](image/Screenshot_2019-04-30_12-31-33.png)
+
+   ![](image/Screenshot_2019-04-30_12-31-52.png)
+
+   Until the `Registration` window appears, select `Trial`, close Navicat after loading is complete, and execute `Step 2`:

+
+2. Download the latest release [from here](https://github.com/DoubleLabyrinth/navicat-keygen/releases), and extract:
+
+   > The 64-bit executable file is downloaded here. If you use 32-bit, please download the corresponding version.
+
+   ```console

+   $ unzip navicat-keygen-for-x64.zip
+   ```
+
+3. Download `navicat-pacther.sh` and `navicat-keygen.sh`:
+
+   ```console
+   $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-patcher.sh
+   $ chmod +x navicat-patcher.sh
+   $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-keygen.sh
+   $ chmod +x navicat-keygen.sh
+   ```
+
+4. Use `navicat-patcher.exe` to replace __Navicat Activation Public Key__ that is stored in `navicat.exe` or `libcc.dll`.
+
+   > Please turn off `Navicat` when performing this step.
+
+   ```console
+   $ ./navicat-patcher.sh

+
+5. Then use `navicat-keygen.exe` to generate __snKey__ and __Activation Code__
+
+   ```console
+   $ ./navicat-keygen.sh
+   ```
+
+   You will be asked to select Navicat product, language and input major version number. After that an randomly generated __snKey__ will be given.
+
+   ```
+   Select Navicat product:
+   0. DataModeler
+   1. Premium
+   2. MySQL
+   3. PostgreSQL
+   4. Oracle
+   5. SQLServer
+   6. SQLite
+   7. MariaDB
+   8. MongoDB
+   9. ReportViewer
+
+   (Input index)> 1
+
+   Select product language:
+   0. English
+   1. Simplified Chinese
+   2. Traditional Chinese
+   3. Japanese
+   4. Polish
+   5. Spanish
+   6. French
+   7. German
+   8. Korean
+   9. Russian
+   10. Portuguese
+
+   (Input index)> 1
+
+   (Input major version number, range: 0 ~ 15, default: 12)> 12
+
+   Serial number:
+   NAVO-2ORP-IN5A-GQEE
+
+   Your name: 
+   ```
+
+   You can use this __snKey__ to activate your Navicat preliminarily.
+     
+   Then you will be asked to input `Your name` and `Your organization`. Just set them whatever you want, but not too long.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+     
+   After that, you will be asked to input the request code. Now __DO NOT CLOSE KEYGEN__.
+
+6. __Set up__ a invalid proxy. Find and click `Registration`. Fill `Registration Key` by __snKey__ that the keygen gave and click `Activate`.
+
+7. Online activation will failed and Navicat will ask you do `Manual Activation`, just choose it.
+
+8. Copy your request code and paste it in the keygen. Input empty line to tell the keygen that your input ends.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+
+   Input request code (in Base64), input empty line to end:

+
+   Request Info:
+   {"K":"NAVO2ORPIN5AGQEE", "DI":"R91j6WyMhxHznAKSxxxx", "P":"WIN"}
+
+   Response Info:

+   ```
+
+9. Finally, you will get __Activation Code__ which looks like a Base64 string. Just copy it and paste it in Navicat `Manual Activation` window, then click `Activate`. If nothing wrong, activation should be done successfully. Don't forget to close the proxy that we just set up.

+# Navicat Keygen - 如何使用这个注册机？ (Linux)
+
+* 维护者：zenuo, DoubleLabyrinth
+
+---
+
+> 可下载[录屏文件](image/Screen_recording.mp4)参考
+
+1. 切换到解压安装包的路径，本示例解压到了 `家目录`，运行Navicat，使其初始化环境：
+
+    ```console
+    $ cd ~/navicat121_premium_en_x64
+    $ ./start_navicat
+    ```
+
+    首次启动时，会提示如下两个窗口，点击“Cancel”即可：
+
+    ![](image/Screenshot_2019-04-30_12-31-33.png)
+
+    ![](image/Screenshot_2019-04-30_12-31-52.png)
+
+    直至出现 `Registration` 窗口，选择 `Trial`，待加载完成后关闭Navicat，执行 `步骤2`：
+
+    ![](image/Screenshot_2019-04-30_12-32-43.png)
+
+2. [从这里](https://github.com/DoubleLabyrinth/navicat-keygen/releases)下载最新的release，并且解压：
+
+    > 此处下载的是64位的可执行文件，若您使用32位，请下载对应版本
+
+    ```console
+    $ curl -O -L https://github.com/DoubleLabyrinth/navicat-keygen/releases/latest/download/navicat-keygen-for-x64.zip
+    $ unzip navicat-keygen-for-x64.zip
+    ```
+
+3. 下载 `navicat-pacther.sh` 和 `navicat-keygen.sh`：
+
+    ```console
+    $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-patcher.sh
+    $ chmod +x navicat-patcher.sh
+    $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-keygen.sh
+    $ chmod +x navicat-keygen.sh
+    ```
+
+4. 使用 `navicat-patcher.exe` 替换掉 `navicat.exe` 和 `libcc.dll` 里的Navicat激活公钥。 
+
+   > 执行此步骤时，请将Navicat关闭
+
+   ```console
+   $ ./navicat-patcher.sh
+   ```
+   
+   __Navicat Premium 12.1.22 简体中文版已通过测试__。下面将是一份样例输出：

+5. 接下来使用`navicat-keygen.exe`来生成序列号和激活码
+
+   ```console
+   $ ./navicat-keygen.sh
+   ```
+
+   你会被要求选择Navicat产品类别、语言以及输入主版本号。之后会随机生成一个序列号。
+
+   ```
+   Select Navicat product:
+   0. DataModeler
+   1. Premium
+   2. MySQL
+   3. PostgreSQL
+   4. Oracle
+   5. SQLServer
+   6. SQLite

+
+   Serial number:
+   NAVO-2ORP-IN5A-GQEE
+
+   Your name:

+
+   你可以使用这个序列号暂时激活Navicat。
+
+   接下来你会被要求输入`用户名`和`组织名`；请随便填写，但不要太长。
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+ 
+   之后你会被要求填入请求码。注意 __不要关闭命令行__.
+
+6. 配置一个不存在的`代理`。找到`注册`窗口，并填入keygen给你的序列号。然后点击`激活`按钮。
+
+7. 在线激活失败，这时候Navicat会询问你是否`手动激活`，直接选吧。
+
+8. 在`手动激活`窗口你会得到一个请求码，复制它并把它粘贴到keygen里。最后别忘了连按至少两下回车结束输入。
+
+   ```

+3. Then use `navicat-keygen.exe` to generate __snKey__ and __Activation Code__
+
+   ```
+   navicat-keygen.exe <-bin|-text> [-adv] <RSA-2048 PrivateKey(PEM file)>
+   ```
+
+   * `<-bin|-text>`: Must be `-bin` or `-text`. 
+  
+     If `-bin` is specified, `navicat-keygen.exe` will finally generate `license_file`. It is used for Navicat old activation method only.
+
+     If `-text` is specified, `navicat-keygen.exe` will finally generate a Base64-style string which is __Activation Code__. It is used for Navicat new activation method. 
+
+     __This parameter must be specified.__
+
+   * `[-adv]`: Enable advanced mode.
+
+     __This parameter is optional.__ If specified, `navicat-keygen.exe` will ask you input Navicat product ID number, language signature numbers. It is for future use generally.
+
+   * `<RSA-2048 PrivateKey(PEM file)>`: The full path or relative path to a RSA-2048 private key file. 
+     
+     __This parameter must be specified.__
+
+   __Example: (in cmd.exe)__
+
+   ```console
+   navicat-keygen.exe -text .\RegPrivateKey.pem
+   ```
+
+   You will be asked to select Navicat product, language and input major version number. After that an randomly generated __snKey__ will be given.
+
+   ```
+   Select Navicat product:
+   0. DataModeler
+   1. Premium
+   2. MySQL
+   3. PostgreSQL
+   4. Oracle
+   5. SQLServer
+   6. SQLite

+   2. Traditional Chinese
+   3. Japanese
+   4. Polish
+   5. Spanish
+   6. French

+
+   Serial number:
+   NAVO-2ORP-IN5A-GQEE
+
+   Your name: 
+   ```
+
+   You can use this __snKey__ to activate your Navicat preliminarily.
+     
+   Then you will be asked to input `Your name` and `Your organization`. Just set them whatever you want, but not too long.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+     
+   After that, you will be asked to input the request code. Now __DO NOT CLOSE KEYGEN__.
+
+4. __Disconnect your network__ and open Navicat. Find and click `Registration`. Fill `Registration Key` by __snKey__ that the keygen gave and click `Activate`.
+
+5. Generally online activation will failed and Navicat will ask you do `Manual Activation`, just choose it.
+
+6. Copy your request code and paste it in the keygen. Input empty line to tell the keygen that your input ends.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth

+7. Finally, you will get __Activation Code__ which looks like a Base64 string. Just copy it and paste it in Navicat `Manual Activation` window, then click `Activate`. If nothing wrong, activation should be done successfully.

+# Navicat Keygen - 如何使用这个注册机？ (Windows)
+
+1. [从这里](https://github.com/DoubleLabyrinth/navicat-keygen/releases)下载最新的release。
+
+2. 使用`navicat-patcher.exe`替换掉`navicat.exe`和`libcc.dll`里的Navicat激活公钥。 
+
+   ```
+   navicat-patcher.exe [-dry-run] <Navicat Installation Path> [RSA-2048 PEM File Path]
+   ```
+
+   * `[-dry-run]`: 运行patcher但不对Navicat程序做任何修改。
+
+     __这个参数是可选的。__
+
+   * `<Navicat Installation Path>`: Navicat的完整安装路径。 
+     
+     __这个参数必须指定。__
+
+   * `[RSA-2048 PEM File Path]`: RSA-2048私钥文件的完整路径或相对路径。
+     
+     __这个参数是可选的。__ 如果未指定，`navicat-patcher.exe`将会在当前目录生成一个新的RSA-2048私钥文件。
+
+   __例如：(在cmd.exe中)__ 
+
+   ```
+   navicat-patcher.exe "C:\Program Files\PremiumSoft\Navicat Premium 12"
+   ```
+   
+   __Navicat Premium 12.1.22 简体中文版已通过测试__。下面将是一份样例输出：
