I would not trust this as-is. I do not like the `curl | sh` install strategy generally, but especially with something like this it feels sketchy.

Yes you can, you got to run a shell script with root privs when the cli was installed. You might only store ciphertext in your DB but skimming the shell script, it's dumping a mystery binary off your digitalocean spaces bucket and giving it all-user execute privs. There is no way to verify that binary isn't skimming my key.
