Decrypt files without rclone?

i have config a remote encryption in gdrive. That works all fine! I want to know if it is possible to decrypt the files without rclone (i encrypted the content and the files names with a password writed by hand, let's say "mypassword").

I can download one of the files and decrypt with other method? I mean without install the rclone, etc.?

Possible? Yes.

Easy? Depends on your skillset.

Rclone is open source so you can see all the code. If you wanted to replicate the decrypt process yourself, that's possible. Just keep the binary somewhere and if rclone exploded off the map, you can still decrypt it but you need the binary to do that.
