1.生成抓包工具证书

Fiddler

输出cer证书hash

openssl x509 -inform DER -subject_hash_old -in FiddlerRoot.cer

输出的269953fb+.0就是android系统证书使用的文件名例如：269953fb.0

转换fiddler证书为base64的明文格式(pem)

openssl x509 -inform DER -in FiddlerRoot.cer -text > 269953fb.0

编辑`269953fb.0`

把"-----BEGINCERTIFICATE-----"到文件结束这部分移动到文件首部

Charles

导出charles证书

Charles->Help->SSL Proxying->Save Charles Root Certificates... Charles导出的证书已是pem格式，无需转换

计算Charles证书hash

openssl x509 -subject_hash_old -in charles.pem

输出类似3abb2d3f的hash值

导入证书

可以adb root

adb root
adb remount 
adb push charles.pem /system/etc/security/cacerts/3abb2d3f.0

2.问题

shell里重新mount system

mount -o rw,remount /system

如果不成功

mount -o rw,remount /

remount报错或者push没权限

adb root 
adb disable-verity 
adb reboot 重启设备 
adb root 
adb remount

Magisk root方式导入

adb push charles.pem /sdcard/3abb2d3f.0
adb shell
su
mkdir -p /data/adb/modules/catransper/system/etc/security/cacerts
cp /sdcard/25c32d7c.0 /data/adb/modules/system/etc/security/cacerts/
chmod 644 /system/etc/security/cacerts/3abb2d3f.0
reboot

Android安装Root证书
