One suggested way to install ssh encryption for this addon
Open a terminal in HA using one of the terminal addons, the Code Server (VSCode) addon, or from the front end of HA pi, etc. Note Home Assistant OS and Supervised mode use the folder /ssl to store the encryption files in. This replaces the ~/.ssh folder many Linux distro's use.
At the terminal prompt:
cd ~/ssl
ssh-keygen -f ~/ssl/something-unique-ed25519 -t ed25519
Change something-unique-ed25519
to something else but the letters ed25519 might help you in future troubleshooting.
Answer the questions. It is not recommended to add a passphrase for this application.

At the terminal prompt:
ssh-copy-id -i ~/ssl/something-unique-ed25519 user@host
where something-unique-ed25519
matches the filename you generated above and user@host
matches the username and host where you are remote storing the data.
The name something-unique-ed25519
will also be loaded in the addon configuration in the SSH private key
box. user
will match the username
box. host
will match the remote host
box.

At the terminal prompt:
ssh-keyscan -H 192.168.x.x >> ~/ssl/known_hosts
where the IP address matches the IP address of the remote host you are sending the file to. host
value can also be used here.
