[Duplicity-talk] Question about Using the Encrypt and Sign Keys

[Charles Knowlton]

I have created 2 different GnuPG keys on my VPS Server.  One used for  
signing and one used for encryption.
Both of the keys have a different passphrase.
On my home computer I have unix and I was wondering could I have  
shell a script from my home unix box
run Duplicity on my VPS and create the backups for me using the GnuPG  
Keys that I have on the VPS Server?

Even better is, can I create 2 different GnuPG keys on my home unix  
box and use them to Sign and Encrypt my backups on
my VPS Server using Duplicity without passing my passphrase over the  
net?  Duplicity is installed on the VPS Server.
