Install latest Mozilla trusted CA certificates on Mikrotik RouterOS

Steps

  1. Get latest CA certificates from Mozilla: https://ccadb-public.secure.force.com/mozilla/IncludedCACertificateReportPEMCSV
  2. Extract PEM format certificates from CSV, using this tool I wrote: https://github.com/inntran/RubyPowerTools/blob/master/bin/csv or DIY ./csv IncludedCACertificateWithPEMReport.csv "PEM Info" > moz-cert-$(date +%Y%m%d).crt
  3. Upload/Copy generated bundle certificate file to RouterOS
  4. Import using command /certificate import file-name=moz-cert-20180101.crt, should replace 20180101 with actual filename.
