AWS hacked account

Sorry,
I enabled the rclone.config encryption, but now, of course when I try to use my original scripts for rclone they fail because rclone.config is encrypted.
I read the wiki https://rclone.org/docs/#configuration-encryption but really it is not very clear to me how I can manage rclone to run with the crypted rclone.config file.
The wiki tals about a paswordstore tools which is not available in my asuswrt system (I have a Asus RTAX88U router) nor in entware distribution.
Can you help me to understand how to run the rclone script with encrypte rclone.config file?

This is my current script:

#!/bin/sh
mv /mnt/NAS/linux/rclone_nas.log  /mnt/NAS/linux/log/rclone_nas_$(date +%F).log
/opt/bin/rclone sync -v /mnt/NAS /mnt/NAS2 \
--backup-dir /mnt/SCRATCH/TEMP_BACKUP/NAS/`date -I` \
--log-file /mnt/NAS/linux/rclone_nas.log \
--delete-excluded \
--size-only \
--min-age 30 \
--max-duration 4h \
--bwlimit 5M \
--filter-from /jffs/myscripts/rclone_nas_filter.txt
wait
