# Issues: https://github.com/acmesh-official/acme.sh/issues/2727
################################################################################
# Usage:
# 1. Set required environment variables (two ways):
# - Create temp admin user automatically
# `export SYNO_UseTempAdmin=1`
# - Or provide your own admin user credential by:
# 1. Set required environment variables:
# - use automatically created temp admin user to authenticate
# 1. disable "enfore 2FA-OTP for admins" via control panel
# 2. `export SYNO_UseTempAdmin=1`
# - or provide your own admin user credential to authenticate
# 1. `export SYNO_Username="adminUser"`
# 2. `export SYNO_Password="adminPassword"`
# 2. Set optional environment variables (shown values are the defaults)
# - `export SYNO_Scheme="http"`
# - `export SYNO_Hostname="localhost"`
# - `export SYNO_Port="5000"`
# - `export SYNO_Create=1` - to allow creating the cert if it doesn't exist
# - `export SYNO_Certificate=""` - to replace a specific cert by its description
# - `export SYNO_DeviceName=""` - required for 2FA-OTP
# - `export SYNO_DeviceID=""` - required for omitting 2FA-OTP (only pro
# users may set)
# - common optional variables
# - `export SYNO_Scheme="http"`
# - `export SYNO_Hostname="localhost"`
# - `export SYNO_Port="5000"`
# - `export SYNO_Create=1` - to allow creating the cert if it doesn't exist
# - `export SYNO_Certificate=""` - to replace a specific cert by its
# description
# - 2FA-OTP optional variables (with your own admin user)
# - `export SYNO_DeviceName=""` - required for 2FA-OTP, script won't require
# interactive input the device name if set.
# - `export SYNO_OTPCode=""` - required for 2FA-OTP, script won't require
# interactive input the code if set.
# - `export SYNO_DeviceID=""` - required for omitting 2FA-OTP (might be
# deprecated, auth with OTP code instead)
# 3. Run command:
# acme.sh --deploy --deploy-hook synology_dsm -d example.com
