I’m using Kodi with drive add-on and someone asks about using rclone decrypting “on the fly”.

The author asks about documentation encrypting the files to implement it to the add-on.
There is some documentation on rclone.org and the source code is available for the developer. He may be able to retrofit. This is a interesting addon I was unaware of. Thanks for sharing.
