But how, for example, would you give me the secret key, from the USA to
Germany, without meeting in person?

 
Diffie-Hellman can establish a secret key in public. Then authenticate
over an encrypted channel.

 
I know, but how do you protect the key on your online device against
Pegasus or FinSpy?

 
Why would you bother? You've got the cart before the horse. First secure
your computing device against spyware. /Then/ think about keeping
secrets on it.
 

You can't secure a device, regardless of OS, against Pegasus or FinSpy,
hence the reaon why people need an offline device for proper encryption
and decryption.
