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>

Create a Revocation Certificate. This should be done as soon as you make the key pair, not when you need it. source

Other GPG commands

List local keys

gpg -k

Prepare your public key for hard copy exchange

gpg --export -a email@address.com > ~/neupokoev.gpg

Upload your key to the server

gpg --send-keys 9F10192825F0EBA5C05FEA5363D4FD2BF3515F41

So anyone can find it

gpg --search-keys email@address.com

But what they need, is to install it from the server

gpg --recv-keys 9F10192825F0EBA5C05FEA5363D4FD2BF3515F41

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?
