Description:
This directory contains the root CA certificates chosen to be trusted by
Mozilla's NSS library, reformatted into an array in C source code, to be
used by the default SecurityContext obect in Dart's dart:io library for
secure networking (TLS, SSL).

The certificates are fetched from Mozilla with the command line

curl https://hg.mozilla.org/mozilla-central/raw-file/tip/security/nss/lib/ckfw/builtins/certdata.txt -o certdata.txt

and then a derived file, with the certificates in PEM format, is created by
running the utility at https://github.com/agl/extract-nss-root-certs:

go run convert_mozilla_certdata.go > certdata.pem

Note that this utility produces a warning about one certificate with a negative
serial number.  This is expected.

Comments are stripped from this file, to decrease the size of the string
that will be compiled into the Dart executable:

sed '/^#/d' ./certdata.pem > ./certdata.stripped

The stripped file is converted to a C character array with the xxd utility:

xxd -i certdata.stripped > certdata.cc

And finally the name of the array is changed to root_certificates and the
MPL copyright header is added back to the file, creating root_certificates.cc.
