这里介绍一下两种不同的挂载证书的方法。
chls.pro/ssl无法在浏览器中下载证书是什么原因
解决方法：
法一
1. 挂载系统分区为读写
使用正确的挂载点来挂载系统分区为读写：
su
mount -o remount,rw /dev/uijISjR/.magisk/block/system_root
2. 确认挂载成功
挂载成功后，可以通过以下命令确认系统分区是否已经挂载为读写：
mount | grep system_root
你应该看到类似于以下的输出，表示系统分区已经挂载为读写：
/dev/uijISjR/.magisk/block/system_root on /system type ext4 (rw,relatime,...)
3. 复制文件
挂载成功后，再次尝试复制文件：
cp /storage/emulated/0/HttpCanary/certs/87bc3517.0 /system/etc/security/cacerts/
4. 恢复系统分区为只读（可选）
为了安全起见，可以在操作完成后将系统分区恢复为只读：
mount -o remount,ro /dev/uijISjR/.magisk/block/system_root
示例操作
以下是完整的操作步骤：
-
获取root权限：
su -
挂载系统分区为读写：
mount -o remount,rw /dev/uijISjR/.magisk/block/system_root -
确认挂载成功：
mount | grep system_root -
复制文件：
cp /storage/emulated/0/HttpCanary/certs/87bc3517.0 /system/etc/security/cacerts/ -
恢复系统分区为只读（可选）：
mount -o remount,ro /dev/uijISjR/.magisk/block/system_root
法二

使用命令frida -UF -l hook_encrypt.js -o log.txt
可以搜索到我随机输入的账号值。但是不能直接搜索到key，说明key被加密了。
加密模式是ECB，Key

通过逆向分析堆栈。发现是经过两次
这里有百分号可以判断是url编码。
解码后的数据还是包含百分号。所以还要再进行一次url编码
接码后的key值中出现了等号，只有在base64加密时出现位数不足的情况，会出现等号。
可以发现原始的key值经过base64编码后有经过两次url编码，才输出到请求中。
这也是Frida自吐框架的局限性。要自己去逆向分析。这里账号和密码还是明文，方便定位。实际的情况可能所有信息都被加密了，所以很难定位。
Frida自吐算法的局限性：
- 加密在java层，调用标准加密库，但是在加密前后对数据进行特殊处理(比如base64编码或者url编码等)
- 加密位置在so层，用C/C++写算法
- 或者加密在java层的自写算法
