First you need to get the certificate hash

openssl x509 -inform PEM -subject_hash_old -in charles-proxy-ssl-proxying-certificate.pem | head -1>toto

i use windows, store it in a var in a matter to automate the process set /p totoVar=<toto

set totoVar=%totoVar%.0 && DEL toto

cat charles-proxy-ssl-proxying-certificate.pem > %totoVar%

openssl x509 -inform PEM -text -in charles-proxy-ssl-proxying-certificate.pem -out nul >> %totoVar%

adb shell mount -o rw,remount,rw /system

adb push %totoVar% /system/etc/security/cacerts/

adb shell mount -o ro,remount,ro /system

adb reboot

  • did you solved the problem ?
  • The only way to install certificate silently is via Device Policy Manager, and only apps (.apks) can register as DPM, so sadly after long research I reached a dead end.@MohamedELAYADI

  • "adb shell mount -o rw,remount,rw /system" not correct, you should use "adb shell mount -o rw,remount /system"
  • I have to also set the cert's permission to 644 to make it work. Otherwise the cert is not recognized.
  • This needs root access right? To edit /system
  • I got this error. ./ssl_pinning.sh: line 3: !!: command not found head: cert_name=.0: No such file or directory
  • @Gorio you might find this script helpful. You will surely need to update it a bit (I couldn't copy the resulting file to the /system partition of the AVD but was successful with Genymotion).
