Before uploading files to cloud storage

Before uploading your files to any cloud storage for backup purposes, it is a good idea to restrict unsanctioned access to your information.

Download gpg. By the way, I do it on Windows.

gpg --gen-key
gpg --output revocation.crt --gen-revoke <your email>

Note: Who is Mallory?

Encrypt for myself

gpg --encrypt --sign --armor -r <your email> <file or archive>

Decrypt

gpg <file or archive>.asc

Upload to storage

Another tool, rclone that just works on Windows as well as on Linux

rclone copy <file or archive>.asc google-drive:

Or maybe someone already created a cloud storge file manager?
