Install User Certificate Via ADB

Question

Is there a way to install CA certificate (.crt file) under the Security -> Trusted Credential -> User tab via ADB? or any other "scriptable" way.

Answer 1

I figured out a way to do this, thus i was able to trust charles proxy certificate. it will be added as trusted SSL root certificate.

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

Answer 2

Thanks to this answer Install User Certificate Via ADB I was able to adapt a script that works on a bash shell:

PEM_FILE_NAME=logger-charles-cert.pem
hash=$(openssl x509 -inform PEM -subject_hash_old -in $PEM_FILE_NAME | head -1)
OUT_FILE_NAME="$hash.0"

cp $PEM_FILE_NAME $OUT_FILE_NAME
openssl x509 -inform PEM -text -in $PEM_FILE_NAME -out /dev/null >> $OUT_FILE_NAME

echo "Saved to $OUT_FILE_NAME"
adb shell mount -o rw,remount,rw /system
adb push $OUT_FILE_NAME /system/etc/security/cacerts/
adb shell mount -o ro,remount,ro /system
adb reboot
