This directory contains a script to generate the content of rtc_base/ssl_roots.h, to update the SSL roots shipped by WebRTC follow this instructions:
Download roots.pem from pki.goog or [curl.se][mozilla-cacert]
Launch the script:
$ vpython3 tools_webrtc/sslroots/generate_sslroots.py <the pem file>
Step 2 should have generated an ssl_roots.h file right next to the pem file.
Overwrite rtc_base/ssl_roots.h with the newly generated one.
