# This script pulls the list of Mozilla trusted certificate authorities
|
|
# from the web at the "mozurl" below, parses the file to grab the PEM
|
|
# for each cert, and then generates DER files in a new ./data directory
|
|
# Upload these to a SPIFFS filesystem and use the CertManager to parse
|
|
# and use them for your outgoing SSL connections.
