# Judge0 Configuration File
################################################################################
# Judge0 is a highly configurable which allows you to use it for many
# different use-cases. Please, before deploying Judge0 take a look at this
# configuration file that is divided in several logical sections that will help
# you understand what can you do with Judge0.
#
# This default configuration file is designed to work out of the box for you and
# you can start with it when deploying Judge0 on your server.
#
# If you have any questions please don't hasitate to send an email or open an
# issue on the GitHub page of the project.

################################################################################
# Judge0 Authentication Configuration
################################################################################
# You can protect your API with (AUTHN_HEADER, AUTHN_TOKEN) pair.
# Each request then needs to have this pair either in headers or
# query parameters. For example let AUTHN_HEADER=X-Judge0-Token and
# AUTHN_TOKEN=mySecretToken. Then user should authenticate by sending this
# in headers or query parameters in each request, e.g.:
# https://api.judge0.com/system_info?X-Judge0-Token=mySecretToken

# Specify authentication header name.
# Default: X-Auth-Token
AUTHN_HEADER=

# Specify valid authentication tokens.
# Default: empty - authentication is disabled

################################################################################
# Judge0 Authorization Configuration
################################################################################
# Protected API calls can be issued with (AUTHZ_HEADER, AUTHZ_TOKEN) pair.
# To see exactly which API calls are protected with authorization tokens
# please read the docs at https://api.judge0.com.
# API authorization ensures that only specified users call protected API calls.
# For example let AUTHZ_HEADER=X-Judge0-User and AUTHZ_TOKEN=mySecretToken.
# Then user should authorize be sending this in headers or query parameters in
# each request, e.g.: https://api.judge0.com/system_info?X-Judge0-User=mySecretToken
# Note that if you enabled authentication, then user should also send valid
# authentication token.

# Specify authorization header name.
# Default: X-Auth-User

# Judge0 uses isolate as an sandboxing environment.
# Almost all of the options you see here can be mapped to one of the options

# check for the isolate documentation here:
