<h2 id="固件解包"><a href="#固件解包" class="headerlink" title="固件解包"></a>固件解包</h2><p>固件工具mkxqimage完成对固件的解包，在解包前先检查Checksum是否正确，然后利用RSA公钥/usr/share/xiaoqiang/public.pem检查RSA签名，这两个步骤通过后，根据[0x0C]的固件类型，以及[0x10]、[0x14]、[0x18]和[0x1C]的4个偏移量拆分固件。</p>
<h2 id="固件打包"><a href="#固件打包" class="headerlink" title="固件打包"></a>固件打包</h2><p>小米官方在打包固件时用RSA私钥计算出固件的RSA签名，小米路由器下载固件后用RSA公钥来验证RSA签名，有效地防止固件被篡改。</p>
<h2 id="固件格式"><a href="#固件格式" class="headerlink" title="固件格式"></a><a href="http://www.iptvfans.cn/wiki/index.php/%E5%B0%8F%E7%B1%B3%E8%B7%AF%E7%94%B1%E5%99%A8%E5%9B%BA%E4%BB%B6%E5%88%86%E6%9E%90" target="_blank" rel="noopener">固件格式</a></h2><p>路由固件的格式，基本是基于 openwrt 的 trx 这个简单的二进制文件格式<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line">48 44 52 30 63 D4 11 03 FE 3D 1A FD 05 00 02 00</span><br><span class="line">20 00 00 00 20 00 FE 00 00 00 00 00 00 00 00 00</span><br><span class="line">FF 04 00 EA 14 F0 9F E5 14 F0 9F E5 14 F0 9F E5</span><br></pre></td></tr></table></figure></p>
<p>第1～4字节：ASCII字符串“HDR0”，作为固件的标识；<br>第5～8字节：4字节整型数0x0311D464，表示固件的大小：51500132字节；<br>第9~12字节：固件的检查和；<br>第13～14字节：0x0005，表示固件中包含哪些部分；<br>第15～16字节：0x0002，表示固件格式版本号；<br>第17～20字节：0x00000020，表示固件第一部分在整个固件中的偏移量，0.4.85固件的第一部分是brcm4709_nor.bin，也就是Flash中除0xfe0000-0xff0000的board_data外的全镜像；<br>第21～24字节：0x00FE0020，表示固件第二部分在整个固件中的偏移量，0.4.85固件的第二部分是root.ext4.lzma，也就是硬盘中128M固件的压缩包；<br>第33字节开始是固件的正式内容开始。</p>
<h2 id="小米开启ssh工具包"><a href="#小米开启ssh工具包" class="headerlink" title="小米开启ssh工具包"></a>小米开启ssh工具包</h2><p>使用mkxqimage解包<br>（现在会提示秘钥不存在）<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">error fopen public key</span><br><span class="line">Image verify failed, not formal image</span><br></pre></td></tr></table></figure></p>
<p>如果能解包应该可以得到脚本文件upsetting.sh</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">#!/bin/sh</span><br><span class="line">nvram set ssh_en=1</span><br><span class="line">nvram set flag_init_root_pwd=1</span><br><span class="line">nvram commit</span><br></pre></td></tr></table></figure>
<p>执行脚本文件upsetting.sh后，将ssh_en设置为1，同时设置了flag_init_root_pwd项。当正式启动时，/usr/sbin/boot_check脚本检测到flag_init_root_pwd=1时，自动修改root用户密码，具体脚本为：<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line">flg_init_pwd=`nvram get flag_init_root_pwd`</span><br><span class="line">if [ &quot;$flg_init_pwd&quot; = &quot;1&quot; ]; then</span><br><span class="line"> init_pwd=`mkxqimage -I`</span><br><span class="line"> (echo $init_pwd; sleep 1; echo $init_pwd) | passwd root</span><br><span class="line"> nvram unset flag_init_root_pwd</span><br><span class="line"> nvram commit</span><br><span class="line">fi</span><br></pre></td></tr></table></figure></p>
<p>初始密码是mkxqimage -I的结果，实际是根据路由器的序列号计算得到。路由器的序列号印在底盖上，12位数字，如：561000088888</p>
<p>初始密码计算算法为：</p>
<p><code>substr(md5(SN+&quot;A2E371B0-B34B-48A5-8C40-A7133F3B5D88&quot;), 0, 8)</code></p>
<p><strong><em>A2E371B0-B34B-48A5-8C40-A7133F3B5D88</em></strong> 为分析mkxqimage得到的salt</p>
