/*
To generate a version of this file containing data for your root certificate,
run the following command from a Linux or Cygwin bash shell, assuming that a
copy of brssl (or brssl.exe) is in the directory where the EasyRSA shell script
is located.

./brssl ta pki/ca.crt | sed -e '1,/br_x509/ d' -e '/};/,+999 d' >local_ca_descriptor.h

Then copy local_ca_descriptor.h into directory include.

Add this line to user_config_override.h:

#define INCLUDE_LOCAL_CERT

Be sure to generate both files: local_ca_data.h, and local_ca_descriptor.h
