Trust different root certificate authorities in Chromium

It doesn't seem possible to change this location.

However, you can set up a new location, create a new database and add certificates $HOMEto it before running Chromium . For example, $HOMEit can be set to--user-data-dir=

It's worth noting that this method starts Chromium from your original home directory and makes some configurations not available for Chromium. At least I noticed that it won't use your desktop theme and downloads will go to the newly created home directory.

To illustrate this, we can grab a script from here that runs Chromium in a temporary directory and modifies it to import the Burp CA certificate before starting Chromium:

#!/bin/bash

BASE_TEMP_DIR=/tmp
CA_CERT=/opt/burp.der
TEMP_DIR=$(mktemp -d $BASE_TEMP_DIR/google-chome.XXXXXXX)

echo "Running Chrome with temp folder in: $TEMP_DIR"
export HOME=$TEMP_DIR
NSSDB=$HOME/.pki/nssdb/
mkdir -p $NSSDB
certutil -N -d sql:${NSSDB} --empty-password
certutil -d sql:${NSSDB} -A -t "C,," -n Burp -i $CA_CERT
google-chrome --user-data-dir=$TEMP_DIR --no-first-run --disable-reading-from-canvas --proxy-server="http://localhost:8080" "$@"

rm -rf $TEMP_DIR
